Questions & Answers

please identify each adjustment item and give concise adjustment procedure for model L7010 lawn genie valve.

lawn genie operation guide in the box does not identify the adjustment components on the body of the anti-siphon valve, (model L7010). therefore adjustment procedure is unknown without location and name of each adjustment item. the instructions relates to a white flow control screw screw knob-(there is no white screw knob on this L7010!!!!) WHICH IS THE BLACK MANUAL BLEED SCREW???? THE ENCLOSED ADJUSTMENT INSTRUCTIONS ARE TOO VAGUE FOR ME TO MASTER!!!!
Asked by: rankin
October 10, 2016 We apologize for the confusion you’ve encountered with the instruction manual for the L7010 valve. We will certainly look into getting the instructions updated so it is less confusing. Steps 5 and 6 in the instruction manual are “optional” if you desire to adjust the flow. The valve is already set from the factory for maximum flow. In regards to the white plastic screw, it is not actually something that is visible on the valve straight out of the box as it has a black cap, or knob, that protects it from vandals. This black cap is the one with the three slits on top. It is not necessary to remove that cap/knob, however, to adjust the screw as you can actually make that adjustment using a flathead screwdriver using the slots on the cap. Turning this screw, or knob, will adjust the amount of desired water flow. Turn the flow control screw clockwise to decrease the flow or counterclockwise to increase the flow. Please note: the flow control screw requires approximately seven turns to adjust from maximum to minimum flow. The manual bleed screw knob (external bleed) is the black screw with the plus sign on top. Turning it counterclockwise will allow water to flow through the valve while you determine the amount of desired water flow needed. You can then adjust the amount of flow control while the valve is open by turning the white flow control screw, or the black cap/knob if you didn’t remove the cap. Once the desired amount of flow is set, you can then tighten the manual bleed screw to close the valve. The bleed plug handle (internal bleed) is used to turn the valve on manually. So essentially, you can turn the valve on manually using the manual bleed screw or the bleed plug handle. One is external, so water will be spraying out, and the other is internal, so water is staying inside and flowing through the valve. You just need to be sure you don’t unscrew the external manual bleed screw all the way or water will be spraying all over. To open the valve, move the bleed handle counterclockwise to the stop. The valve will open as discharge water is routed internally downstream. To close the valve, move the handle clockwise until resistance is felt. Do not overtighten!

How do I install a PVC check valve ?

Asked by: Vms
If you are installing a check valve, you will want to follow the manufacturer’s suggested installation procedures. It would be best to check your local codes to make sure a check valve, or a pressure vacuum breaker, is required in your municipality when installing anti-siphon valves.

Does one need to cut the pVC pipe to replace it or can one just unscrew it?

Too much backflow at the end of the cycle.

Asked by: riad
The standard boiler plate answer for backflow was stated above. Here it assumes that your sprinker sysem is on relatively flat ground. Unfortunatly there are yards that have slopes and hills higher than the primary water source. This means using the rule where the valve must be higher than the sprinkler head cannot be implemented. There is a inexpensive solution to back flow on sprinkler heads that rise above the valve. That is install a PVC Check Valve, They can be purchased for 3/4 and 1 inch PVC pipe for around $8. They prevent water from flowing downhill into the Anti-siphon valve.

3/4 in. 150 psi Anti-Siphon Valve with Flow Control is rated 4.2 out of 5 by 43.

This looks like the exact same valve I used back then. I'm sure the model number and some of the construction is different, but it is an exact replacement size wise. My only concern with these valves and many of the others on the market is the fact you have to glue them in place. It would be nice if they had some kind of union joint built in. The delivery is the only other complaint. It takes 10 days or so to get them. The price seemed reasonable though.

Rated 5 out of 5 by from Previous one worked for 18 yrs. Only time will tell how long it lasts but the new one seem identical to the old. It was hald the price than the irritrol valves at my old house...and in some cases these lasted much longer being plastic rather than metal irritrols.

Used all screw on fittings to put it together , added the filter and a 20 psi pressure regulator. Had everything done, up and running in less than a hour. Hope to get at least 5 years out of it.

Rated 4 out of 5 by from Convenient Convenient. these valves are convenient when needing to repair as you just buy another valve and spin-off the main functioning parts of the valve and spin them on to the old valve never having to remove the old valve
