4 Things to Look For In an Overheating Pump  

WP Law - Thursday, September 13, 2018
agricultural-irrigation An overheating water pump can shorten the life of the motor and cause damage to surrounding piping. Even a brand new pump can get too hot and suddenly stop working and have to be replaced. 

Save money and hassle. Know the warning signs of an overheating pump. Here's what you need to know:  

1. You Can't Touch It 

If you can touch the pump (not the motor) without feeling any significant heat, then the pump is probably working as it should. But if the pump feels hot to the touch (be careful) or you see steam, then it is running too hot. This applies only to the wet end. Electrical motors will feel hot to the touch even under normal conditions as most run at an ambient temperature of 40 degrees C, which is over 100 degrees F. This will feel hot to the touch. Of course a motor running at a temperature above 40 degrees C can be an indication of a problem with the motor. 

2. The Pump Sounds like Rocks Are in It 

If your pump is making a noise that sounds like rock are tumbling inside, then the pump is probably cavitating. Cavitation can occur if the suction lift is too high, the suction line is partially blocked or the temperature of the liquid being pumped is high. Cavitation can cause serious damage to the impeller of the pump. 

3. It's Losing Prime 

The internal components of a pump depend on the fluid flowing past them to keep them cool. If the pump loses prime, then the water inside of the pump casing can get extremely hot (due to the friction of the impeller) and eventually turn to steam. When this happens, the high temperature can damage seals, the impeller, and even plastic piping connected to the pump. The most likely culprits to cause a pump to lose prime are a small air leak in to suction line or a leaking shaft seal. 

4. Look for Clogs 

A clog in the suction line or strainer may be restricting the flow of water and can cause cavitation or loss of prime. Either of these conditions can cause the pump end to overheat. 

5. The Motor is Drawing too Much Current 

The motor name plate includes some important information. Two pieces of vital information are the motor service factor (SF) and the full load amps (FLA). Amperes or amps is the unit of measure of electrical current and is an indication of how hard an electrical motor is working. At a given voltage, the higher the amps the more work a motor is doing. The FLA listed on the motor name plate is the amount of current that that particular motor should draw when it is under full load. The FLA can be exceeded by the amount of the service factor, but anything higher is considered excessive and can be an indication of a motor or pump problem. Several factors can cause a pump to draw too much current. Among those are the pump is operating at the far right hand of the pump curve; a mechanical issue such as bad bearings; a bad winding in the motor; or the pump is wired to the incorrect voltage. 

Don't Ignore an Overheating Pump Ignoring it could cost you. If you don't know why it's overheating, call an expert. We can help.

3 Signs You Are Losing Money Due to a Hidden Irrigation Leak

WP Law - Monday, September 10, 2018
agricultural-irrigation We use irrigation systems today to keep our lawns, gardens, and other grassy areas looking good without the hassle of having to water it every day. Sometimes though, there may be issues with your irrigation system that you may not even be aware of, due to most of the system’s components being hidden underground. Here are some indications that you may have a hidden irrigation leak that is costing you money: 

Signs Your Irrigation System is Leaking

  1. Your Lawn is Dying – Seeing dry, brown spots of grass is a certain indication that it is not getting enough water. There may be a loss of water to those areas due to reduced water pressure in your irrigation system. Getting too much water due to a leak is also an issue, which can kill root tissue.  
  2. Soggy Patches – Leaks in your irrigation systems can leave soggy wet spots on your lawn. If you see areas that are consistently wet and/or feel soft and muddy when you walk on it, this typically indicates a problem with the irrigation system. 
  3. Higher Water Bills – Often, the first sign of an irrigation system leak is a water bill that is higher than usual. Look at your water meter and if it is constantly turning, and all other leak sources such as washing machines, toilet, and sinks are working properly, this is a good indication your irrigation system is the problem. 

The experienced team at W. P. Law, Inc. is ready to help with your irrigation project no matter the size.

3 Ways To Troubleshoot Sprinkler Head Issues

WP Law - Thursday, August 23, 2018

If you have an irrigation system installed on your property, you know how critical it is to have it working properly. When sprinkler head issues arise, they need to be taken care of as soon as possible to prevent water waste, crop damage and more. Here are three ways to troubleshoot sprinkler head issues.

1. Uneven Spray

Watch your sprinkler head when it’s in action. Is the spray consistent, or does it sputter, or produce an uneven spray? If it’s the latter, the problem might be as simple as a clogged sprinkler head. Lawn cuttings, dust and dirt can get kicked up while you’re mowing, or during heavy rainfall. It lands on your sprinkler head and clogs the holes where the water comes out. You can remove the nozzle and clean any debris that may have accumulated.

2. Yellow grass

If you have yellow grass in an area around a sprinkler head, you probably have a leak. Overwatering almost always leads to yellowing. To check, walk around the area and see if the ground feels spongy. You can also watch the area while the sprinkler system is running and see if you notice water bubbling to the surface. If you notice either of these problems chances are you have a leak and you will need to dig down to the pipe to locate and repair it.

Take care of this as soon as possible, because even one leaking sprinkler head can drive up your water bills.

3. Dead Grass

If you have an area of dried or brown grass, then that area is not receiving adequate water. Typically this means that a sprinkler head is not rotating or a zone valve is not opening. Simply watch the system while it is operating and see if you have a head that is not rotating. If that is the case, then simply replace it. If you have an area where several sprinklers are not popping up and working, then you most likely have an issue with a valve or a programming error on your controller.

These are three easy ways to troubleshoot common sprinkler head issues. For more assistance with your sprinkler system, contact us today.

What a Soil Test Can Reveal About Your Lawn

WP Law - Thursday, August 09, 2018

The quality of your soil is crucial for a healthy lawn and landscape. Here's what a soil test can tell you:


Most soil has at least some clay, silt, and sand in it. A soil composition test can tell you how much of each is present in your soil, relative to the amount of soil. If your soil has too much of one or more of these ingredients, it can affect how your soil drains and in turn your plant’s health.

Nutrient Content

For optimal growth, your soil should have a number of nutrients, including but not limited to:

  • Nitrogen
  • Potassium
  • Phosphorous
  • Magnesium
  • Calcium
  • Iron
  • Copper
  • Zinc

Each type of plant or grass requires different levels of certain nutrients. A soil test can tell you what nutrients are present in your soil and in what amounts, so you can add or reduce as necessary depending on what you plan to plant in the area.


A soil test can also tell you if there are any contaminants in your soil, such as mercury, cadmium, lead, arsenic, and barium. If your lawn or plants have been doing poorly despite your best efforts, a soil test can let you know if contaminants are the culprit.

Good growth requires good soil, and the first step to getting good soil is to know what's in it. Contact W.P. Law, Inc. for more information on getting a soil test that gives you the information you need to get started.

Ultimate Guide to Getting the Most Gallons per Minute out of your Well  

WP Law - Thursday, July 26, 2018

In most states, including South Carolina, building codes require that your well deliver at least three gallons per minute (GPM) or more. However, the minimum is not necessarily the optimum amount of water for your family and its multiple needs. A qualified well driller can help you determine the best location for your well and can give you an idea of the expected capacity based on his experience of drilling other wells in your area.

1. Check for clogged or leaking pipes.

One of the first things to check on your well system is to make sure there are no broken or leaking pipes within the well. A broken well pipe can possibly cause your well pump to overheat and damage the motor.

2. Use a well yield increase method.

There are a number of methods that are used to fracture the rock within a well to help increase yield. A commercial product, such as AquaFreed, can help increase the well's yield as can the use of materials like frozen CO2.

3. Install a water holding tank.

Using a cistern along with your well allows you to store water on days when the well is flowing smoothly and have it on hand for those days when the well is dryer.

Three Common Mistakes People Make When Watering Their Lawn  

WP Law - Thursday, July 05, 2018

A lot of money and effort goes into keeping your lawn looking healthy. Poor watering habits often have the opposite effect on your grass. Make sure you’re not indulging in any of these bad watering techniques

Watering When It’s Hot

Don’t make the mistake of watering during the day while the sun’s beaming down. Water evaporates quickly and never makes it to the grass roots, leaving your grass still thirsting for refreshment.

Try watering early in the morning while it’s cool to give water a chance to sink down into the soil.

Using Too Much Water

Many people respond to brown spots in their grass with more water. You could end up depriving your roots of oxygen by oversaturating them and they will suffocate and die. Limit your watering days and do regular checks to your irrigation system to keep it functioning properly.

Watering at Night

The best time to water is early in the morning. This allows the blades of the grass to dry during the day. Watering at night allows the grass to stay damp for long periods of time thus causing your lawn to be vulnerable to disease and insects.

4 Reasons We Love Residential Sprinkler Timers

WP Law - Thursday, June 28, 2018

Sprinkler water timers are an efficient way to manage and keep your home’s irrigation needs in check. They can save you a lot of time, effort, and money in watering your lawn, helping you kill several birds with one stone.

Here are a few reasons why we love sprinkler water timers:

They take the guesswork out

Sprinkler water timers help you take the guesswork out of your lawn irrigation and maintenance. They let you establish a watering schedule that ensures your lawn is irrigated regularly. Even when you are not around, water sprinkler timers ensure your lawn is consistently watered at the set intervals.

They guarantee saturation

Lawn watering is never about making the grass wet. Too little water or too much water for your lawn is unhealthy. Therefore, lawn watering should be about saturating the soil and getting water to the grass' roots to nourish it. Water timers help you achieve this by ensuring the lawn is watered at the appropriate time and at the right place, guaranteeing perfect saturation at all times.

They offer customizability

With season changes, or even with day-to-day weather changes, it’s vital to change your watering schedule to fit each weather pattern. Water sprinkler timers help you customize your watering schedule to adapt to each season or weather change, all year round.

They save money

Water timers help you save money by regulating the amount of water used watering a lawn. Without water timers, your sprinklers don’t know when to stop, and if you are not around, they can flood the lawn.

Consider installing sprinkler water timers on your lawn today and enjoy all the above benefits. Contact the professionals at WP Law Inc. for more on timers!

3 Signs Your Irrigation System Has a Leak  

WP Law - Thursday, June 21, 2018

When you irrigation system is functioning properly, you can look forward to a lush, green and healthy property. But if the irrigation system develops a leak, all your efforts will go to ruin unless you quickly mitigate the problems. Here are three signs your irrigation has a leak.

1. Soggy Spots

If you’re walking around your property and notice that one area feels soggy or boggy underfoot, you may have detected a leak in your irrigation system.First, eliminate the possibility that the sogginess is simply a result of surface water accumulation due to a recess in the land topography. If not, investigate the irrigation system near that location to determine the exact source of the leak.

2. Unusually High Water Bills

Carefully monitor your water meter and bills so that you have a baseline for your property's normal water usage in each season. A prolonged increase in water bills could mean that the water company has raised their rates, so it’s important to review your water meter readings in tandem with the water bills. If you notice a spike in the water bill along with unusually high meter readings, you may have a leak in your irrigation system.

3. Plants are Unhealthy Looking

Your irrigation system should ensure that all parts of your property are receiving adequate hydration. If you begin to notice that certain areas of your property are looking unhealthy, this is a sign that you may have an irrigation system leak. Telltale signs of an irrigation leak include yellow patches in one area, which indicates over watering, and dry, brown patches in another, which indicates that the leak is limiting water accessibility in that area due to reduced water pressure.

An irrigation leak that is left untended can wreak havoc with your property and profits. At the first sign of an irrigation leak, contact WP Law. We can help to determine the exact source of the leak, and implement solutions to take care of it.

How Powerful Does My Sprinkler Pump Need to Be? Learn now

WP Law - Thursday, June 14, 2018

Are you looking to keep your grass green and your garden growing all summer long without wasting resources? At W.P. Law Inc. we have the solution to your problem. Sprinkler pumps are the solution. They are designed such that they save you money while at the same time conserving resources. Sprinkler pumps provide a steady flow of water while providing enough pressure to push water out of the sprinkler head.

Several factors will affect the water pump used. They include;

How high are you pumping the water?

Before purchasing a pump, we advise our clients to measure the amount of lift required from the surface of the water source to the pump. It is much easier for the pump to push water out than it is for it to pull water up. Therefore, the higher you have to pump the water, the more powerful pump you need.

How far are you pumping the water?

The distance the water has to travel before it reaches the sprinkler heads will also affect your pump choice. The longer the distance between the pump and the sprinklers the more the friction, and the more powerful the pump should be to maintain optimum flow and pressure.

How wide is the area the sprinklers have to cover?

To figure out which pump you should purchase you should consider the area the sprinklers have to cover. First, you have to calculate the gallons per minute (GPM) for each sprinkler and then add them up. The sprinklers' GMP and PSI (Pounds Per Square Inch) will affect the sprinkler pump required.

The terminology used regarding pumps can be confusing to most people. If you need help figuring out which pump you need, consider contacting W.P. Law Inc. for expert advice.

A Beginners Guide to Irrigation Filters  

WP Law - Thursday, May 17, 2018

Every irrigation system needs some type of filter to keep sand and debris from clogging the system or causing serious damage. The type of filter that you use will depend on your specific system needs. An irrigation filter can require a bit of routine maintenance, but it is an inexpensive form of insurance that will keep your irrigation system running year after year. Here's a beginner's guide to some of the different types of irrigation filters.

Screen Filters

Screen filters are usually the most cost effective filter and also the most common. They're really good at keeping sand out of a system. However, if your water contains a lot of organic debris, you'll want to go with an automated self-cleaning screen filter.

Spin Clean Filters

A spin clean filter is a unique type of irrigation filter that stays clean while it's in operation. These filters move debris, especially sand, across a screen and into a basin where it can be collected and drained. As long as your water pressure remains consistent, the filter will clean itself, reducing the amount of maintenance needed for the system.

Media Filters

If you've ever seen a swimming pool filter, chances are it was a media filter. These filters use a type of media (usually sand) to stop debris. The water is forced through the media and when any debris hits the media, it stops because it can't fit between the spaces. Sand comes in in different size ratings, so you will want to choose a sand that is appropriate for the type of debris you want filtered out.

Disc Filters

A disc filter uses a container filled with a stack of round discs. When water is forced through the filter, the discs catch any organic debris or sand and trap them. Disc filters are highly effective, but they have to be flushed or manually cleaned.

If you're not sure what type of irrigation filter you need for your situation, contact us at WP Law. We're happy to answer any questions you might have about irrigation filters.
