Three Great Sprinkler Systems for Your Money

WP Law - Wednesday, July 05, 2017
Air Filter

There is no such thing as one sprinkler system that fits every application. In addition to soil type and the amount of water required, you have to consider details like pressure and flow requirements, application rate, and spacing. The good news is, you have economical, effective options for practically any situation. Here are three solid options:

Spray Head: This system does precisely what the name implies. It sprays water in a fixed pattern. It does not rotate or change directions. Spray heads are typically used in small irregular shaped areas. Although spray heads are used to cover small areas, the have high application rates and are run for short periods of time. Spray heads should ever be run with other types sprinkler heads.

Rotor: These sprinklers are often installed at ground level and rotate a stream of water over a medium to large coverage area. Unlike a spray head, you can water a more expansive area with fewer sprinkler heads. They are also quiet when operating.

Impact: You'll know an impact sprinkler as much by its sound as by sight because of the rhythmic impact the sprinkler arm makes as it hits the water stream. This sprinkler has a coverage area similar to rotors. Because of their design, that simulates natural rainfall) impacts have a higher uniformity than other types of sprinklers.

Beyond these basic sprinkler types, you still need to consider details like nozzle size, pressure and space. That's where the professionals at WP Law can help. Please contact us any time for professional advice on the right sprinkler system for you.

Understanding Water Pump Terminology

Marketing W. P. Law, Inc. - Wednesday, June 21, 2017

When it comes to pumps, it's best, to begin with learning the terminology so you can accurately talk with an industry representative about your needs when you're ready to make a purchase. Additionally, knowing the lingo will provide you with the knowledge you'll need going forward to maintain that system and to help diagnose any potential problems.

Here is a list of the most commonly used pump terminology.

Air Bound. Occurs when the centrifugal pump body fills with air and the pump loses prime and a vacuum can't be formed. When trying to re-prime the pump there must be a way for the trapped air to escape and allow fluid to fill the pump casing.

Cavitation. This happens when vapor bubbles implode. Cavitation can cause catastrophic pump failure if allowed to continue over a period of time. Cavitation usually occurs in applications where there is a high suction lift.

Friction Loss. This is the term used to refer to any reductions in pressure that are caused by turbulence such as when water flows through the hoses, pipes, fittings, and elbows.

Net Positive Suction Head (NPSH). Is the head (pressure) that allows water to flow into the suction opening of the pump. The NPSH-Available is a function of where and how the pump is installed (suction lift, suction friction losses, water temperature, elevation relative to sea level, etc). The NPSH-Required is a function of the pump manufacturer's design of the pump itself. The NPSHA must always be greater than the NPSHR for the pump to function properly.

Performance Curves. A performance curve charts the total dynamic head (TDH) or pressure as it relates to flow rate.

Static. A term used for acting by weight and not by motion. This is the opposite of dynamic.

Strain Relief Protector. This is the support that keeps any given electrical cord used in a submersible pump from being pulled out of place accidentally.

Thermal Overload Sensors. These sensors are built-in to most small horsepower (3HP or less) single phase pump motors. These sensors will shut the pump down if the operating temperature gets too high.

Volute. The volute is also called the pump casing. The volute is where the impeller rotates and pressure is developed.

Water Hammer. When a sudden stoppage in the flow of water from the pump occurs, the water hammer is the energy that's transmitted due to that stoppage.

The Bottom Line

This is just a brief overview of pump terminology. We encourage you to take a few minutes to learn as much pump terminology as you can. Going forward, this will help you make more informed decisions about your equipment and how it all works.

5 Ways to Maximize the Efficiency of Your Irrigation System  

Marketing W. P. Law, Inc. - Wednesday, June 14, 2017
Duo Pro dual-contained piping system

If you have an irrigation system, or if you're thinking about installing one, you should also think about the best ways to make it more efficient. This will help conserve water and help save money on your water bill as well.

Here are five ways that will help maximize the efficiency of your irrigation system.

1. Use Irrigation Controllers

Irrigation controllers allow you to control your watering by day and time. Most automatic irrigation systems are divided into zones. The irrigation control turns on each zone at a specified day and time and allows it to run for a set period of time. Automated irrigation systems use much less water than manually controlled irrigation systems.

2. Install a Smart Irrigation Controller

A smart irrigation controller will adjust the water supply based on your particular landscaping need while taking into account how much rain you've had. Smart controllers also allow you to take into account the type of plant material that you are watering as well as your soil type. These can be installed new or retrofitted.

3. Purchase a Rain Sensor.

A rain sensor will automatically turn off your irrigation system while it's raining.

4. Use High-Efficiency Sprinkler Heads

Replace your old sprinkler heads with new high-efficiency nozzles. This will minimize wind drift and ensure that the water is applied evenly across your landscaping.

5. Water at the Right Time and at the Right Intervals

It's best to water your landscaping in the early morning to help avoid mildew and evaporation. Additionally, watering in a way that supplies your plants with water when they can best use it is key. It's better to water your landscaping deeply less frequently rather than more often with shorter watering times. This encourages deep root growth which will provide you with a healthier landscape.

The Bottom Line

Maximizing the efficiency of your irrigation system doesn't have to be hard or time-consuming. But you do need to learn about what to look for and how to make the necessary corrections when problems are discovered if you want your system to function efficiently and effectively at all times.
W.P. Law Incorporated was founded in 1970 and has a stellar reputation in the industry. We offer top quality products and economical solutions for all our customers' needs.

Why Pump Maintenance and Care is So Important

Marketing W. P. Law, Inc. - Wednesday, June 07, 2017
Duo Pro dual-contained piping system

It would be nice if we could simply install our pumps then let them do their thing, without us having to continually monitor and maintain them. But unfortunately, that's not how things work. That means it's your responsibility to implement a maintenance and monitoring schedule for all your equipment, especially your pumps if you want them to give you the best, most efficient performance possible. Not to mention lengthen their life expectancy. 

Why You Should Monitor and Maintain Your Pumps

In an industrial plant, all processes are fluid. That means formulations change and the different production rates will vary. But their supporting pumps, unfortunately, don't change with them. Therefore, you are going to need an extremely vigorous maintenance and monitoring program if you want to maintain your pumps reliability and efficiency. This will allow you to make any adjustments necessary to keep your pumps in peak operating condition at all times.

The Four Basic Facets of a Pump Maintenance Program

There are four basic facets of a pump maintenance program and they are as follows:

1. The pump's performance monitoring and system analysis.
2. The pump's vibration monitoring.
3. The pump's bearing temperature.
4. The pump's visual inspections.

Each of these maintenance items are indicators on their own. But collectively, they provide you with the big picture of the actual condition of your pump.

The Six Basic Facets of a Pump Monitoring Program

There are six components you should be monitoring if you want to understand how your pump is performing. And they are:

  • Suction Lift (vacuum)
  • Discharge pressure
  • Flow
  • Pump speed
  • Pump power

The Bottom Line

It's crucial to the performance, effectiveness and life expectancy of your equipment to implement a pump maintenance and monitoring schedule. Not to mention reducing the chances of having to pay for extensive repairs. Take some time to learn the industry best practices for maintaining and monitoring your pump equipment. Any time you spend doing this will pay you back in time and expense going forward.
If you would like more information about setting up a monitoring and maintenance schedule for your pumps, or any of your other fluid handling systems, please Contact Us today. W.P. Law Incorporated has been an industry leader since 1970. We look forward to showing you just how powerful an effective pump monitoring and maintenance program can be.

My Water Pressure Fluctuates, What’s Going On?

WP Law - Thursday, May 18, 2017
Duo Pro dual-contained piping system

When your water pressure is fluctuating, a number of problems can be going on. Water pressure issues are most common in homes with a private well system, but can occur anywhere. If your water pressure is strong one minute and weak the next, it could be one of the following problems.

Your Water Filter is Clogged

If your water pressure goes low, your first step is to check the water filter for your home. When the filter gets clogged, you won't have the water pressure you are used to. If the clog is only partial, you may notice your water pressure going up and down.

Sediment is Stuck in Your Faucet

Sediment buildup is another common problem in most homes that will lead to water pressure fluctuations. Sediment builds up over time, and gets stuck in the aerator screens on the end of the faucet. You can try to take the aerator screen off of the end of your faucet to see if any sediment comes out. The screen comes off by screwing it off. Run the water for a minute with the aerator off to see if this fixes the problem.

When Your Water is Hard or Has High Iron Content

If your home has hard water or there is a high iron percentage in your water, this can cause clogging in the lines that provide water to your faucets, rust to develop, or buildup from the hard water.

If you aren't sure why your water pressure is fluctuating, be sure to contact us, and we'll find the answers to your problems.

Soil: How Does it Help Determine the Sprinkler I Use

WP Law - Thursday, May 11, 2017
Duo Pro dual-contained piping system

When people are thinking about adding a sprinkler system to their lawn to help with irrigation, they often think about the cost of the system and the size of their lawn before moving forward; however, it is important for people to think about the soil type as well. The type of soil plays an important role in the sprinkler system and should be considered along with the other factors before deciding on a sprinkler system.

The Intake Rate of the Soil

One of the factors that people need to consider with their soil is its intake rate. The intake rate is the term given to the rate at which the soil absorbs the water. Soil that has a high intake rate soaks up water faster than soil with a low intake rate. If the soil has a high intake rate, the sprinkler system can apply water at a higher rate; however, if the soil has a low intake rate, the soil cannot absorb as much water as quickly and the sprinkler system run times would need to be adjusted so that runoff is reduced.

The Water Retention of the Soil

The water retention of the soil is the term used to describe how well the soil holds on to the water. Soil with a high retention rate holds on to water and does not need to be watered as often. People need to consider the water retention of the soil before deciding on a sprinkler system because it determines the frequency of the water treatments.

Reach out to your local irrigation experts to discover the perfect system for your lawn. We'll discuss every factor that should be considered when selecting an irrigation system, along with your individual needs. Contact WP Law, Inc today and let's get started on creating a healthier lawn for you!

3 Signs You’re Ready To Upgrade Your Well Pump

Whether you use your well for intensive irrigation, industrial piping, or simple residential fountains, a consistent and affordable water supply is essential. If your well relies on outdated pumping technology, however, none of these devices will work to their full potential. To know whether it's time to upgrade your pump, look out for:

1. Electrical Excess

Obsolete pumps use more energy to move the same amount of water as modern ones. If you notice an unusually high electric bill, your well may be to blame. Replacing the pump with modern model will improve efficiency, paying for itself through lower electrical bills.

2. Sisyphean Service

In addition to wasting energy, obsolete pumps break more often and require more extensive service to fix. If you are constantly spending money and time on your well, consider cutting your loses and replacing it. Newer models can work for up to twenty years before needing repairs, thus reducing your long-term maintenance costs.

3. Pressure Problems

Traditional pumps struggle to deliver water at the same pressure throughout the system, especially if you use multiple water sources at once. Modern pumps, however, can do this without skipping a beat. If you find that pressure varies during the day or with more intensive water use, you could use a pump upgrade.

Should I Water My Lawn In The Winter?

WP Law - Friday, January 27, 2017

Summer months for homeowners are typically spent outside, tending to a healthy and well-maintained lawn. However, when the first frost hits in the south, many homeowners are left wondering what they should do for their lawns in order to ensure their grass comes back in the spring just as lush as it was when it went into dormancy in the fall.

Why Lawns Need Less Water in the Winter

During the winter months, the growth rate of many types of grasses found in South Carolina slow considerably. When paired with the changing temperatures, it is easy to see why lawns would need less water to survive. Lower temperatures tell your lawn to go into a dormant winter state in order to survive the cold frost and occasional snow. Regulating how much water your lawn receives during the winter can ensure you never over-water or neglect your dormant grass. A good way to maintain your lawn without having to constantly monitor how much you’re watering is to install an irrigation system. An irrigation system can help you regulate watering times and amounts.

Should You Water Your Lawn in the Winter?

The answer to this question relies heavily on the current conditions. In South Carolina, the temperatures can vary from day to day. On colder days, you may not need to water your lawn. However, on days when the temperatures rise and you have not gotten rain in some time, you should consider it. Do not be alarmed by the color of your lawn changing to brown, however. This just means the grass has gone dormant. It is not dead and should continue growing in the spring. Your watering schedule should take into account the temperature and the recent rain amount, not the look of the grass.

Why is a backflow preventer necessary in my piping system?

WP Law - Thursday, October 06, 2016
sprinkler system

When talking to an irrigation specialist, you will hear a lot of jargon. One of those is backflow, which goes along with backflow preventer valves. Your installer will no doubt tell you how important it is to prevent backflow.

What is backflow?

Backflow is when water (or another fluid) flows through a piping system in the wrong direction. It is most often caused by a sudden drop in water pressure, which can happen any time you are attached to a municipal system – like if the fire service opens a hydrant a few streets over.

Why is backflow from your irrigation or piping system bad?

Any kind of backflow is bad. If, for example, you have a lawn irrigation system in your yard, the water used for irrigation will sit in underground pipes for days before the system turns on. Contaminants such as fertilizer, lawn care chemicals and even pet waste can be drawn back into the system if backflow occurs. Backflow can transmit this contaminated water back into the municipal piping system or even your home’s piping system. In industrial systems, backflow can also cause cross contamination with the municipal system or even contamination among other fluids used within the industrial process.

How do you prevent it?

Other than avoiding sudden water pressure drops, which are not always avoidable, backflow is prevented by a backflow preventer or valve. There are a variety of types, depending on the application and risk of backflow contamination. The type of backflow prevention device required is usually dictated by local and state codes. Your local water purveyor usually has a list of approved backflow prevention devices available on their website. A backflow preventer contains check valves that only allow flow in one direction. If a sudden drop in pressure occurs upstream of the backflow preventer, the check valves will close and block the flow of water back "upstream" into the system.

Preventing backflow is a key aspect of proper design of an irrigation or piping system. Contact a professional such as W.P. Law, Inc. to help you prevent potentially contaminated water ending up in your kitchen faucet, or worse.

Pre-Winter Pond Care Checklist

WP Law - Thursday, September 29, 2016
Pond with Koi fish

It's not too early to start thinking about getting your pond or outdoor water feature ready for fall and winter. Pre-winter maintenance is easy and vital to the health of your pond. Failing to take these steps may create the need for expensive repairs or modifications in the spring. Here are the steps you should take to prepare your pond for fall and winter.


• Keep leaves from falling into your pond with netting. The netting will prevent leaves and other debris from entering the pond, making for very easy cleanup in the spring.• Change out up to half of the water. This step will remove contaminants and create better water condition to get through the winter. It's best to do this when the temperature of the pond water is roughly the same as the water source. Just make certain the temperature is above 60°F to prevent stress to aquatic life.
• Add a conditioning agent with bacterial additives. Make sure the agent is formulated to work during colder temperatures.
• Clean organic matter from the bottom of the pond.

Water Pumps

• Clean pond pump filters thoroughly.
• If the water temperature gets below 45°F, turn the pump(s) off and remove the filter media and main pump. This will keep freezing temperatures from damaging the pump.
• Drain the pump according to the manufacturer's instructions.
Plants • Winter non-hardy plants indoors or in a greenhouse.• If you have hardy water lilies, clip off any pads and buds and place the lily in the deepest part of your pond where the tuber will not freeze.


• When the water temperature gets lower than 70°F, you'll mix wheat germ food with your koi's regular feed. The wheat germ formula helps digestion.• When temperatures get below 60°F, feed wheat germ food exclusively.
• If the water reaches 40°F, don't feed koi at all.

If you have any questions relating to winterizing your pond, contact the experts at W.P. Law today!
