Water Park Pumps

Water Park Pumps

    Recently I went to a water park here in SC to examine the pumps that run the lazy river water feature as well as the pumps that operate the water slides and various other water features throughout the water park.  The primary focus was on the lazy river water pumps.  These particular pumps circulate water throughout the park creating that river effect for people to enjoy floating around the water park.  Lazy river pumps are generally just centrifugal pumps that recirculate water in the man made channel and boost water pressure to make that churning effect of being on a river.  


These pumps operate with virtually no elevation difference and the only back pressure on the pump is generated by the discharge openings in the channel.  When installing these pumps always remember to install a throttling valve on the discharge side of these pumps.  Never install a throttling valve on the suction side of a pump as this just creates cavitation problems and will eventually destroy the impeller and the bearings in the pump.  This is a common mistake a lot of people make so don’t let this happen to you. 


Installing a throttling valve on the discharge side of your lazy river water pump will allow you to control the flow to keep the pump from overworking itself.  This throttling effect actually causes the pump motor to run at a lower amperage thus increasing motor life and saving energy.  It also keeps the pump from having suction cavitation issues from moving too much water.  A third and final advantage to installing a throttling valve on your lazy river water pump is it increases the velocity of the water exiting your piping which increases the flow through the channel thus making the lazy river more effective.

NDS EZ-Flow Drain Pipe

  W.P. Law Inc. is now stocking a drainage product that will make French drains a piece of cake. EZ-Flow drain pipe will not only save you time, money, and equipment cost, it will increase your profit on drainage jobs.  With EZ-Flow drains ease of installation, minimal equipment need, and not needing gravel delivered to the work site, it will allow contractors that have not engaged in offering French drains to now do so.

EZ-Flow drain pipe will be a welcome product to the contractors doing crawlspace drainage. No more carrying gravel under the house in 5 gallon buckets, just carry the pipe and its self contained aggregate with you and place in the trench. Working in those tight spots will no longer be as challenging or time consuming. Stop by your local W.P. Law branch and take a look at your new money maker.

Remote Control for Your Irrigation System


You have a T.V. remote, a stereo remote, ceiling fan remote, garage remote, car remote and maybe some of you even have remotes for your spouse and kids…so why not an irrigation system remote?

Today’s technologies are ever evolving and attempting to make our lives easier in this fast- paced rat race we constantly try to survive in. Irrigation systems are not what they were ten years ago, even five years ago!  Irrigation has become more automated and is advancing just as computers, cell phones, and televisions have in recent years.

Manufacturers now have hand held remotes (ie. Rain Bird LIMR  and Weathermatic SLRC-KIT-HUB) that can be used to retrofit to their controllers so that with relative ease and reasonable cost you can sit on your porch and turn on your irrigation system. You can advance through the zones and programs to check the system and locate valves for troubleshooting.  If you are out of town frequently, there are systems that can be monitored and controlled using a computer that has internet access, a phone line, ethernet and in some cases a smart phone (ie. Tucor: RKS ,RKD, and TWC or Rain Bird IQ ).

These systems will allow you to change schedules, programs, run diagnostic test, set-up safeties to guard against leaks, log data, and contact you if there is a problem. There are also controllers that are called “smart irrigation controllers” that know what the weather is in terms of temperature, rain, humidity, and wind. As well as, they know what type of grass, soil, and sprinkler heads are in your yard. These “smart controllers” decide how long your system needs to run in order to apply the correct amount of water for your grass and plants’ needs. (ie. Weathermatic Smartline, Rain Bird  ESP-SMT, and Tucor)

Your property is very valuable to you monetarily and aesthetically. Keeping it up can be very rewarding, but also take-up a considerable amount of your precious time. Upgrading your irrigation system with some type of remote system can make your life easier and even your yard greener.

If you would like more information on ways to remote your irrigation system, please visit our website at www.wplawinc.com or call one of our local offices.
