Rainstat Irrigation Repair in Waco | Sprinkler Repair, Backflow, Drainage and Smart Controllers

Sprinkler Repair

Business is Good–But It’s Not All Our Fault

We try to do the best we can. But, as far as I know, no one else in the area does what we do. We don’t install sprinkler systems (normally). We don’t mow grass. We don’t do landscaping. We don’t spray weeds.

Installing a sprinkler system is pretty simple after you do it a couple hundred times. Everything is under the installer’s control. S/he plans the system, digs the trenches, connects the pipes, plumbs the heads, runs the wires and connects them to the controller mounted in the garage. Before s/he covers everything up, the workers compare what they see on the ground to the plan.

Put another way, if you have workers that understand how to put all the pieces together and how to run a trencher, then the most important piece in the puzzle is the sprinkler Plan. If the Plan is engineered correctly and the workers did what they were supposed to do, voila!, it’s done. —>>>

Please, now, consider repair. Everything’s been running fine for years until . . .Zone three quits working. (If you are picturing what I have in my mind, the skill difference between someone who installs a sprinkler system and someone who repairs one, is evident and huge.) There is nothing visual to indicate 1. that zone three has quit working or 2. that this yard even has a sprinkler system!

Who are you going to call? Here’s your choices: 1. The landscaper/irrigator/mower/jack-of-all-trades person who charges by the hour, or, 2. the one who does sprinkler repair only and guarantees his price and gets your okay before he ever starts the job?

If you chose the sprinkler repair specialist with the guaranteed up-front price, may I respectfully submit Rainstat Irrigation as your provider?


We are looking for a hero

Someone who realizes our footprint on this planet needs to be soft with a eye toward the future. We can look at nearby cities like San Angelo, Austin and San Antonio to see that our “right” to water is tempered by its availability. And its availability is definitely NOT a given. We want to help you use all the water you need, and not a drop more. We do this through ensuring your automatic sprinkling system is working efficiently and waters only when the plants need it–and for only the amounts needed.

So, who are we?  Rainstat Irrigation is a sprinkler system repair and upgrade company in Waco, Texas.  If you have a landscape or lawn irrigation system, you can consider us a resource to repair broken heads, malfunctioning irrigation controllers, wiring problems, backflow devices that don’t work or water that needs drainage.  Too, we are central Texas’ most experienced smart controller experts.  Your weather-based controller saves you trouble and money on your water bill by watering only enough–all year long.



You know you need drainage help when water is where it’s not supposed to be.


The most obvious need is when heavy rains bring water into the house or garage. Drainage needs also show up when rain washes dirty water into your pool or rain forms a stagnant pond.

Although we are not foundation experts, we have seen our heavy clay soils reek havoc to foundations that have a fluctuating moisture content. Keeping puddles of water away from your foundation may help.


We will use gravity instead of pumps because gravity never quits. Pumps have their place, but often our heaviest rains are accompanied by electricity-interrupting conditions–which, of course, makes the solution no solution at all. Proper drainage is accomplished by placing one or several catch-basins where water accumulates. These catch-basins are connected to an underground piping system that carries the water down to a lower discharge point.


What we’re trying to accomplish is a landscape that accepts all the water it can, and then discharges any excess to the city’s waste-water treatment system. In rural areas, we are simply trying to find an on-purpose place for the water to go.



We cut our teeth in this business as landscapers, so maintaining an excellent, scar-free landscape is our primary goal. A normal installation will involve cutting the turf off the top of the trench, opening the trench, leveling it to an acceptable grade, installing the pipe and basins, backfilling the trench and re-installing the original sod. We try to make it look like we were never there.


Every drain job we have ever done has been very different. That’s okay because we will come out to your property with a transit and other measuring devices and give you an up-front price. Free. We call it a Promise because we don’t want people to confuse what we do with an estimate. Our Promise price will be your invoice price.



Every lawn sprinkler system or drip sprinkler system must have a device that prevents the water it carries from re-entering the public water supply. That device is called a backflow device.

We are licensed to install, test, repair and upgrade your backflow device. If you are in Waco, the code changed significantly in 2009. Essentially, the city of Waco restated that, yes, the same type of backflow device you probably already have is okay. It’s called a DCA or double-check assembly. It’s a big piece of bronze that’s buried in the ground.

But here’s something that has changed. Now, if your sprinkler system doesn’t have a way of turning it off without having to turn off all your water, you must put in a valve for that purpose. It’s called an isolation valve and it’s probably a good idea. Hopefully, you already have one.

The other requirement is placing a “wy” filter upstream of your backflow device. The intent is to protect your backflow device against contamination and failure.

So when do you have to do this? Any time your sprinkler system undergoes a “major” repair. Major Repair is defined by the state as anytime your mainline is exposed to the atmosphere. Huh?

Your backflow device is ON the mainline of your sprinkler system. So, obviously, if you have to repair your backflow device, you’ve opened your main to the atmosphere. So, you have to bring it up to code before you can put your system back into service. That also happens if you have a mainline break or if you have to repair or replace a valve.

A Letter From the City

You may have gotten a friendly letter from the city stating that you have so long to get your backflow device tested and certified. They’re just doing their job in protecting the water we drink. If you get that letter and would like for us to certify your backflow device, please give us a call. It’s painless and we take care of all the paperwork with the government.

Rainwater Harvesting

Frankly, we’re new at this.

We have had a rainwater catchment system at our house for several years and a lot of the people in our community have it as well. So why are we just coming on the scene with such an obvious need to conserve water?

Because . . . If you intend to use rainwater to water your landscape, you’d better have a big, big house (lots of roof area) and a tiny yard. Don’t get me wrong, we think we NEED water catchment. It’s better water, it’s free and it’s like a savings account–you store it up for when you need it. Just have realistic goals for how your intend to use it. The water purveyor has a major mishap and you’re without water for several days. Here’s an article on what happened in Kemp, Texas.

A StoryA few years ago we were asked to install an irrigation system at a rich guy’s place. The foreman for the land said we had unlimited water. Even though the wells and catchment system weren’t all that strong, they had a custom, 10,000 gallon tank built so the yard could have all the water it needed. We designed the system for this 7 acre complex and figured out a way to portion out his water supply so we could water everything. But, unlimited? Not hardly!I calculated that, if we turned on all the system’s zones at one time (we wouldn’t/couldn’t), we would drain his tank in just over 3 minutes.
