It doesn't work! If the original brand used is not available, you have two choices: Mixing them is like putting a heavy kid and a light kid on a teeter-totter. (It makes sense doesn't it? They want you to use their sprinklers for replacements, not the other guys! You can't use Chevy parts in a Ford either.) Mixing different brands and models of sprinklers together on the same valve circuit can result in huge amounts of water wasted. While there are exceptions, most manufacturers use different flow rates in their sprinkler heads than their competitors. Most brands and models of sprinklers are not compatible with any other brands or models. Mixing different brands and types of sprinklers together on the same valve circuit is a common mistake made by do-it-yourselfers. If some of the sprinklers are already mis-matched you need to replace them so that all the sprinklers controlled by any single valve are matched. Be sure to replace broken sprinklers with the same brand and model as the other sprinklers on the same valve circuit. Straighten any sprinklers that are leaning. Replace any broken or malfunctioning sprinklers. I typically lean the sprinklers slightly toward the top of the slope on my systems, but most experts do not agree with me on this, so I may well be wrong. ![]() You may need to lean it a little toward the top of the slope to correct the problem. When a full circle sprinkler head is located at the bottom of a slope it is a common problem for it to spray directly into the ground on the downhill side. If the uphill side is spraying almost straight up into the air, you need to lean the sprinkler a bit toward the top of the slope, otherwise the water is just spraying straight up and all falling in the same place, or blowing away. With the sprinkler turned on, look at the spray pattern. ![]() On steep slopes you may want to lean the heads slightly toward the top of the slope. However you need to use comon sense here. On slopes the general standard is to position the sprinkler heads perpendicular (at a right angle) to the slope. If they lean to one side they may create dry spots and also waste lots of water. On a level area this means they would be positioned straight up and down so that they do not lean towards any side. In most situations sprinkler heads need to be installed so that they are perpendicular to the ground to work correctly. Straighten any sprinkler heads that are leaning to the side. Here's a bit of trivia to stick in the back of your brain until needed: if the controller no longer shows the correct time after a power failure the problem is likely that a battery needs to be replaced in it. Depending on the model, you may need to remove some screws or unhook a latch to open the panel and get to it. The battery is often located behind the front panel of the controller. Replace it if it is not fully charged, or if it is more than a couple of years old. ![]() Check the battery in the irrigation controller. Typically it is a standard rectangular shaped 9-volt alkaline battery. Most irrigation controllers have a back-up battery that maintains the time and program during power failures. Look for wet spots that indicate there might be a leaking irrigation pipe. Turn on each valve, one at a time, and carefully inspect your irrigation system. Sprinkler System Tune-up Step 1:Ĭheck for problems. Unfortunately the lack of uniform names makes it confusing. On the controller the valve circuits may be called valve stations. The valves might be manually operated, or they may be automatic valves that are turned on and off by a controller (sometimes called a timer or irrigation clock). Most sprinkler systems have several valve circuits, each controlled by a different valve. ![]() Sometimes the term hydrozone is also used, although this is not a totally correct useage. Rotor-Type Sprinkler Heads with Single Stream.Ī valve circuit or valve zone is a group of sprinklers that are all turned on and off by the same valve.
