If you have a well pump, then choosing sprinklers is not quite as straightforward as it otherwise would be. If you choose the wrong sprinklers, it will put unnecessary wear and tear on your pump, which can then burn it up. On the other hand, as long as you know what to look for, you should be able to choose sprinklers and design a sprinkler system that will work with your pump.
Sprinklers are designed to run at a certain pressure. Picture putting your thumb on a hose. If you have a trickle of water coming through the hose, not much will happen when you put your thumb over the hose. On the other hand, if you have a full head of water coming down the hose, putting your thumb over the hose will create a jet of water. In order to make sure that you have the right pressure for your sprinklers, you will have to find out what pressure the sprinklers are designed for, then check your pressure tank. The pressure tank works like the storage tank on an air compressor. If you are not getting enough pressure from your outside spigots, then you should crank up the pressure on the pressure tank. Just make sure that you don't go over the pressure that your tank is designed to hold.
Gallons per Minute
The second thing you need to check is how many gallons of water your system generates per minute. To check your flow rate, simply get a stopwatch and a five-gallon bucket. Turn on your faucet and have a friend operate the stopwatch to see how many times you can fill the bucket up in a minute. Remember to pause the stopwatch whenever you have to empty the bucket to make sure that you get an accurate reading. Once you know the flow rate your system generates, you can start choosing heads. Each head will use a given number of gallons of water per minute, so knowing your flow rate will help you figure out how many heads you can put on each zone.
When you design your system, you want your pressure tank to drain to the point where your pump kicks on to refill the tank. The pressure in the tank should then climb and hold steady with the pump running until your sprinklers shut off. It is better for your pump to run for an hour or more as your system churns through each zone than to for it to turn on and off constantly. If you doubt your abilities to design a good sprinkler system for your well pump, consult a sprinkler technician and your pump installer to make sure you get a system that will operate like it should.

Hi, I'm Carey Johnson. Mold can be more dangerous than you might realize. I learned that when my little girl started having asthma and allergy attacks inside the house. I couldn’t figure out what was causing it. We changed the filter in the air conditioner frequently, and we kept the house very clean. We couldn’t, however, figure out where the allergens were coming from. Finally, we discovered the mold that was growing on the floor of the attic – right above my daughter’s room! No wonder she was having breathing problems! Once we found it, we went right to work learning how to get rid of it for good. We ended up reconstructing the attic, and I learned that I enjoyed learning about construction.
