Orbit sprinkler pressure
Comments (0)Hi, I installed 4 sprinklers for a small area 7' x 25' of lawn with an Orbit sprinkler. The sprinklers are rated at 5,68 LPM/1,7 -- 1.50 GPM @25 psi (12'). These ended up over spraying the area I want so I purchased some Orbit dual-spray sprinklers so they could hopefully cover the immediate spots of concern. After install, these dual spray sprinklers did not fully extend upon turning on the system. It seems like there was not enough pressure to get these sprinklers working. These are rated at 2,84 LPM (a 1,72 bar) and 0.75 GPM @ 25 psi (different than the first set I had installed). Why is it that the second set could not work with my water pressure? I assume the spring rate is different. I could not find dual-spray male Orbit sprinkler nozzles for my first set of sprinklers.... What are my options? Thanks in advance....See MoreHow to get 1/4' sprinkler heads to work.
Comments (2)Hi Aulani, One more thing in addition to the above post is to make sure the number of sprinkler heads do not exceed the output of your water source. Each head uses a portion of the flow and pressure up to their rated amount. the ones closest to the source get their allotted amount, but the end of the line may only be getting a portion of the flow and pressure and don't operate efficiently or at all. If all heads are not working it is a source problem, if only ones close to the source get more water; then you need to limit the number of heads in that area and add more zones.

Comments (3)Hi Craniac, Could be all the above. 9 gpm doesn't tell the whole story but is a start. You need to find out the pressure of the system. There are inexpensive pressure meters ($10 at HD) that screw on to your house connection point. This will be the system pressure of your house after your house pressure regulator in the garage. Your irrigation system can be connected before or after your house pressure regulator. I would guess with 16 heads your connected before the regulator and have street pressure which should be 60 to 80 psi. The house regulator limits this to 40-60 psi for appliances and faucet o-rings safety. Easiest is checking the heads for clogging. Unscrew irrig. head and look inside and clean. Let us know the system pressure and then we can help you more. You may have a faulty valve, clogged filter etc. Tell us about more details of your system. Thanks.

Comments (2)If you were a little more specific.. What brand and part# is the head you are putting on? Did you just dig around it and unscrew it, or did you extend the supply tubing? Did you check to make sure that you did not cut the tubing while digging? Are the other heads the same as what you are installing? When you say that you removed it and there was no pressure, are you saying the hose end (with no head attached) had no pressure? ---------------------------------- Suggestion ------------ If the new head was attached and the head had no pressure... and if it is a commercial head... there should be a ring that holds the bottom and top section together, Unscrew the ring and pull out the inside piece. Turn it upside down. You should see a filter screen. Using a pair of pliers, you can grab one of the filter's "Wings" and pull it out. Clean it and reinstall. If the problem persists, and you have a good flow from the line, take the head back and get a new one. Tom...See MoreMrHIrrigation
