Finding the perfect kind of pipe is important in ensuring a long-term plumbing and chemical management solution that will allow you to rest assured your pipes are built to last. There are two very popular kinds of pipe that are used for many projects: PVC and CPVC pipe. Understanding the difference between these pipes is vital, find out now!

PVC and CPVC

PVC pipe is a widely recognized modern alternative to metal piping. It’s known as a low-cost solution with the strength, versatility, durability, and easy installation process to back its popularity. PVC is made of polyvinyl chloride, a widely used thermoplastic material that can be molded into different shapes.

CPVC is best described as a ‘cousin’ to PVC pipe. They share many common traits, such as basic material composition, but they shouldn’t be used interchangeably. CPVC is able to withstand a much wider range of temperatures than PVC pipe. This attribute means that many building codes require the use of CPVC instead of PVC.

Different Composition

PVC pipe is made of polyvinyl chloride which is unsafe when handling any temperatures above 140 degrees Fahrenheit. PVC is able to resist certain chemicals better than its cousin, which can affect your decision to install one versus the other. PVC is commonly used for unheated water such as for vent and drainage systems, cold water systems, and recreational use.

CPVC is altered by a free radical chlorination reaction that increases the chlorine content of the pipe. CPVC is able to safely handle higher temperatures than PVC, up to 200 degrees Fahrenheit. CPVC is more suited for higher temperature water, and certain kinds of chemicals.

Cost Effective Solutions

PVC pipe is the cheaper, more common choice for many builders and companies. The material it is composed of and the wide range of uses it offers can sway many buyers towards the cost-efficient choice.

CPVC is more expensive than PVC pipe but can be used in more builds. It can handle higher temperatures and more chemicals. Compared to other kinds of pipe, CPVC is still a viable and smart choice for a pipe system.

The Benefits of Dual-Contained Piping Systems

WP Law - Monday, March 06, 2017
Duo Pro dual-contained piping system

There are several options to choose from when considering piping systems in commercial buildings and industrial processing plants. One of those options is called a dual-contained piping system. For those who might be unaware, a dual-contained piping system is used to move fluids that are either highly corrosive or potentially extremely harmful to the environment. This piping system has several benefits that everyone should keep in mind.

Dual-Contained Piping Systems Provide Safety Benefits

A dual-contained piping system piping system is essentially a pipe within a pipe. The primary purpose of this type of system is to provide a "back-up" piping system in the event that the primary piping system was to develop a leak. Most dual containment piping systems utilize what is known as a leak detector.  Leak detectors are sensors that are placed in the space that exists between the inner and outer pipes.  These sensors detect if fluid exists between the two pipes thus indicating a leak.  Leak detectors then notify maintenance personnel that a leak exists and the general location of the leak.  Maintenance personnel can then schedule a repair. Because the leak is contained within the external pipe, employees and the environment are protected from exposure to potentially dangerous chemicals.

A Dual-Contained Piping System Can Lower Costs

Companies that use highly corrosive or caustic chemical as a part of their manufacturing process can benefit greatly from the use of dual contained piping systems. By preventing exposure to the chemicals and the resulting lost time injuries, companies can potentially reduce their workman's compensation costs.

Whether you rely on a sump pump to keep your basement free of water, or a well pump to ensure your home's water supply is always on tap, you're likely interested in keeping your pump running smoothly for as long as possible. Pumps, like any other mechanical device that operates on a steady basis, do wear out and fail.  However, there are a few preventative measures and some warning signs that will let you know if trouble is on the horizon.

Monitor Pump Performance

Pay attention to the performance of your plumbing fixture performance in your home.  If the water pressure in your shower doesn’t seem as strong as it once was, or it seems to take longer for the bathtub to fill.  All of these issues could be symptomatic of reduced pump performance.  Of course there could be other reasons for these problems including a small leak, but taking time to check your pump is also a good idea

Keep Up With Maintenance

The best diagnostic tools you have are your eyes and your ears.  Listen to your pump operate.  If you hear mechanical noises that you have not heard previously, this could be an indicator of possible pump trouble.  Loud noise could be indicative of bearings failing, or even cavitation.  Also look for leaks around pump shafts and casings.  These leaks could be a sign of seal failure which if left unattended could cause motor and bearing failure.

Metal fabrication is an important part of designing numerous structures across a wide variety of industries. With this in mind, people need to make sure that they are receiving quality metal fabrication for the cost that they are investing. What are some of the most important factors to consider?

Who is Performing the Metal Fabrication?

The experience of the shop furnishing the metal fabrication is important. Make sure to ask about the industries that the metal fabrication business has served. Different industries have different requirements and people need to ensure that the needs of their business line up with the capabilities of the metal fabrication provider. For example, many people are in need of pump and filter piping fabrication. Choosing a company that has experience in piping and irrigation metalwork is key to a durable, reliable system.

How Durable is the Metal Fabrication?

Nobody wants to make repairs to a product or system before they have to. This means that the durability of the metal fabrication is important. Investigate the various options for metal fabrication and make sure that the proper metal is chosen for the job. Durability is important for both longevity and the budget. Many people invest in transition fittings and zee pipes that are subjected to large forces and a lot of wear and tear. Be sure to invest in materials that won't break prematurely.

What Kind of Maintenance is Required?

Maintenance is one of the many ongoing costs industries must face. Different metal fabrication jobs will have different maintenance needs. While this maintenance is important for ensuring the longevity of the project, it could also represent a large cost that the business should consider. Sprinkler stands, hydrants, and other aspects of irrigation systems require proper care just like any other piece of equipment. Invest in quality materials that will last with minimal routine maintenance.

Signs Your Building Needs Its Existing Piping Upgraded

WP Law - Friday, January 06, 2017
Building Pipes

When people invest in a building for either residential or commercial purposes, they must think about the quality of the utilities. Utilities have important implications for both the safety and budget of a building’s upkeep. When it comes to plumbing, people should keep their eyes open for a few signs that indicate that the piping needs to be upgraded.

What have the water bills done recently?

One of the most common signs that the piping of a building needs to be upgraded is a dramatic increase in the water bill. As piping grows older and degrades, leaks start to develop. This means that water is leaking from the pipes without being used. This will be reflected as a rise in the utility bills.

Has the water changed in appearance?

Aging pipes have trouble retaining their surfacing. Older pipes were made with different materials that may start to flake off in the water as it degrades. This could discolor the water and has important implications for the safety of people using it. Keep an eye on the appearance of your water because it could signal a time for an upgrade in the pipe quality.

How is the water pressure?

Water pressure is another easy way to determine the quality of your building’s piping. If the water pressure is very weak, you could be looking at a leaking pipe and ultimately, a failing system. A leaky pipe means that some of the water coming to your faucets, showers, or toilets is being lost along the way, which can lead to bigger health risks such as mold or mildew.

When did the pipes go in?

Depending on the age of the building, the piping may have degraded over time. While modern pipes use PVC material, older buildings might have used copper, brass, iron, or galvanized steel. All of these have different lifespans and a good way to understand more about your building’s utilities is to contact a professional for more information.

Anyone with questions should contact WP Law with any questions or concerns regarding building quality and management.

The Best Uses for Dual Containment Piping Systems

WP Law - Thursday, August 04, 2016
Pipes stacked up

Dual containment piping systems offer an extra layer of protection in the transport of hazardous materials. These systems include a secondary pipe enclosed around the main piping system for added protection against breakage and leaking.

The EPA now mandates the use of dual containment piping systems for many types of materials transport. The goal is to avoid leaking of waste or hazardous substances into the environment while they are being transported.

Dual containment piping systems are made of high quality materials to ensure safety and long-lasting viability. High-density polyethylene plastic, polyvinyl chloride, polypropylene, and stainless steel are some of the most common materials used.

The Top Scenarios Where Dual Containment Piping Systems Should Be Used Include:

Wastewater treatment pipes- A dual containment piping system should be used where a waste water pipe come near a drinking water catchment area.

Hazardous waste landfills- Drainage from landfills for hazardous materials should be kept out of the environment via dual containment piping systems.

Remediation sites- The removal of contaminants or pollution from the soil, groundwater, sediment, or surface water is made safer through the use of dual containment piping.

Fuel storage and transport- Tank farms and fuel storage systems must conduct business in accordance with area safety regulations, and a dual containment system can be crucial.

Processing plants- Runoff or drainage from product or food processing plants must be disposed of safely, and dual containment piping offers an added layer of security.

Chemicals and acids- Dual containment piping systems should also be used in the transport of toxic chemicals and corrosive acids.

Toxic gas transport- Gases used in semiconductor manufacture or other processes should be transported with a dual containment system.

Dual containment piping systems are extensively tested during manufacture to ensure quality and viability. However, including a leak detection system within the dual containment piping can assist with becoming aware if a carrier pipe has become compromised.

Considerations such as pressurization of the lines, underground installations, the concentration of the material, space constraints, UV ray exposure, thermal expansion and contraction, environmental factors, and possible chemical combinations should all be considered when selecting a dual containment piping system.

If your company or government agency requires a dual containment piping system, contact W. P. Law, Inc. to learn about your best options.

How Can I Maximize The Efficiency Of My Pump?

WP Law - Thursday, June 02, 2016
Pump

If your pump runs inefficiently, it wastes energy, and you needlessly pay costly energy bills. Luckily, there are ways to make your pump run more efficiently. Are you doing these five things?

1. Using the Correct Size of Pump

Pumps come in a range of sizes, and you need to pick the size that best matches your needs. If your pump is too large, it will waste energy every time it runs, compared to using a smaller more efficient pump. In contrast, if the pump is too small, it will run constantly and waste energy.

2. Replacing Old Inefficient Pumps With Efficient Ones

Pumps come with different levels of efficiency built into them, and if you are using an older pump, it may not be as efficient as a new pump. Ideally, you want to replace old, inefficient pumps with new pumps that advertise premium efficiency.

3. Keeping Your Pump Clean

Occasionally debris and marine life can become stuck in the impeller vanes and reduce pump efficiency. To prevent all of these risks, periodically inspect the pump’s intake strainer to make sure it has not been damaged. If it is attached to a filter or a screen, change or clean those elements on a regular basis to avoid buildup of minerals or debris.

4. Maintaining Your Pump

Like most machinery, pumps require periodic maintenance if they are to perform reliably. Depending on what type of pumping equipment have will determine what maintenance needs to be performed. You should make sure that bearings are properly greased and belts are tensioned correctly as needed. If there are oil reservoirs on your pump, make sure that they are full and that the oil is clean. Some pumps require periodic adjustment of the impellers and packing glands. Impellers should also be checked for blockages, from time-to-time.

5. Adjusting and Maintaining Auxiliary Elements

In addition to ensuring your pump is as efficient as possible, you also have to keep an eye on the elements that work alongside of your pump. For example, if you have a pump as part of your irrigation system, you need to make sure that your sprinklers are releasing water correctly. If there are not, it could cause your pump to work overtime and waste energy.

Advantages of Using Multi-Port Valve Blocks

WP Law - Thursday, April 07, 2016
Multi-port valve block

Multi-port or 3-way ball valves are found in a variety of fluid handling applications in wide range of industries. Multi-port valves are found in chemical and plating operations, the food and beverage industry, and in waste water treatment facilities just to name a few. These valves can be used in draining, cleaning, feeding, and distribution applications. The benefits of these products include a greatly simplified distribution system and reduced risk of leaks.

Applications and configurations

Multi-port ball valves are typically used in industrial fluid distribution applications. They can be used to mix two different fluids or to divert the flow of fluid from one direction to another. Other applications include use as sampling valves and drainage valves. The ball design in a multi-port ball valve usually has one of two common configurations, the “L” port or the “T” port. Some manufacturers such as Hayward Flow Control have as many as four ball configurations.

Multi-port valves can be equipped with a variety of features:

  • Electric or pneumatic actuation
  • Position indicators
  • Lockout/tag out capability
  • Multiple ball configurations
  • Multiple material of construction options

These are just some of the many advantages of multi-port valves. Contact us today for more information.

4 signs your lift station may need professional attention

WP Law - Thursday, March 17, 2016
Inspecting a Lift Station

In nearly all cases, lift stations work properly when regularly maintained by an experienced professional. Even when maintained, problems can arise, and if not dealt with properly and soon enough they can lead to significant and even long term problems. It is always best to contact a professional team for repairs, but some situations definitely warrant a call sooner rather than later. If you are having sewer related problems, it's best to call in the pros.

1. High Level Alarm

The most obvious sign that there is a problem with your lift station is the high level alarm sounding. High water level alarms produce an audible and visual (flashing light) signal that the water level in the sump is rising. This is usually an indication that the pump is not working at all or that it is not pumping at a high enough rate to keep up with the amount of water coming into the sump. If this happens, you may have a lack of power going to the tank. Check the breakers to determine the power is on. If this does not work, you may need to replace the flat switch for the pump.

2. You Have a Strong Odor

If you have a sewer odor, this is generally coming from the basement or from your sump outdoors and may warrant a call to a professional to determine the underlying problem. Odors from the bathroom should also be taken care of by a professional. Keep in mind these odors can signal problems with drains being blocked.

3. Sewer and Water Backups

Another common reason to call a professional is happens when there is a sewage or water backup. This typically occurs due to a blockage but can also be caused by a pump failure.

4. Drainage Is Slow

In most situations, drains provide an indication there is a problem. Over time, they slow down. This may not be noticeable at first, but it becomes noticeable as the problem worsens. You can troubleshoot here, but it is best to have a professional out instead.

You Need Immediate Help

Troubleshooting doesn't always work and takes time. For faster results, call a team of professionals instead especially if your system is complex.

Pump Repair Is Necessary

Pump repair and fabrication is often necessary when pump stations fail or become inefficient. Older systems are more commonly in need of a repair sooner. Do not put off such repairs. Instead, call the professionals out to help you immediately to get your pumps working the best they can. At W.P. Law, we can help you immediately.

Choosing valves for corrosive environments

WP Law - Thursday, March 03, 2016
Inside of a W.P. Law Location

Selecting the right type of valve for any project isn't always as easy as it may seem. There are a variety of factors that must be taken into consideration to ensure that the valve will provide years of uninterrupted service. Not only does the fluid passing through the valve need to be considered, but the environment in which the valve will be operating is equally important. Valves may operate in a variety of environments depending upon the application. Valves that operate in agricultural and construction environments typically only have to worry about the elements. However, some industrial valve application must operate in highly corrosive environments. These corrosive environments can limit some of the options for a valve’s components making the selection process difficult. So how do you make the correct valve selection? Here are some things to consider.

What Makes The Environment Corrosive?

The environment and the type of corrosion resistance required will vary from one project to the next. Is the corrosive environment caused by salt spray near the ocean, chlorine fumes in a commercial pool pump room, or acidic gases in a plating operation? These are just some of the examples of corrosive environments that valve must operate in. Know what is creating the corrosive environment is the first step in finding the proper valve. Many people immediately look at stainless steel as a solution. However, in many cases there are thermoplastic valves that are better suited and much more cost effective.

Functionality Matters

Aside from corrosive resistance, it is also important to consider the overall durability required of the valve. Impact resistance, fatigue strength, and UV resistance are all factors to consider as well. Metal valves may be better suited for applications where there is a high risk of physical damage.

Factors to Keep In Mind

When selecting valves for any application, consider the following:

  • What is the fluid flowing through the valve?
  • Is the valve in a corrosive environment?
  • What is the risk of physical damage?
  • What are my options? Metal vs. plastic.
  • Other factors that make the application unique.

Overall, each situation requires careful consideration of the application in which the valve will need to perform. To get the help you need in selecting the right product, contact W.P. Law, Inc.
