Customer Questions & Answers

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.

How to install?

Asked by: AG
Attach your supply and irrigation line to the valve using ¾” Schedule 40 PVC Male Adapters (for example, The Home Depot SKU number 188-131). The connection between the adapters and the supply lines should be made using the appropriate PVC cement. Once connected to your supply and irrigation line, use grease caps (waterproof wire nuts) to connect one of the solenoid wires to your white wire (neutral) and the other to one of the colored wires. The white and colored wires should run back to your controller with the colored wires being connected to the watering zones and white being connected to the common, or “C”, post.

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
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!

Do you carry a 1'inch ANTI SIPHON VALVE, or is 3/4 a standard size.

Asked by: jim
Yes, we make 1” anti-siphon valves. We offer our Lawn Genie model L7010 or our Toro model #53764. Both products are professional-quality Jar Top valves with Flow Control for precise adjustment.

Rated 5 out of 5 by from needed needed for repair of the sprinkler system in my yard to replace the broken.

Rated 4 out of 5 by from This valve is good, old green one bad This valve is replacing the older Green Lawn Genie valve that broke off just above the input line boss. Wasted 2000 CF of water. Valve in protected area, no sun and never froze. Recommend changing all old green valves. A second one broke but not as bad. The plastic cracked allowing the valve to turn on.

Rated 3 out of 5 by from Replaced an old one Bought these to replace old ones already installed. The flow control is the weak point on these units. When it breaks we buy new unit, take the flow control out and swap it, and throw away the rest.

Rated 5 out of 5 by from Just what the doctor ordered Though these valves may be considered as 'new and improved' or 'updated' the valve body design is the same as my 20 year old valves. With that said the replacement process and procedure was simple and easy. I replaced 4 20 year old valves within 2 hours. I would rate the price and quality of these valves between very good to excellant. In fact I would suggest if you need only the solenoid, the valve body or just the internal parts your better off buying this complete assembly in lieu of individual replacement parts. Thus the parts that are left over will become your spare parts supply when needed.

Rated 5 out of 5 by from 3/4 in. 150 psi Anti-Siphon Valve with Flow Control I have 20yr old lawn genie values - this is a direct replacement. Some of the new valves the inlet and outlets are ~ 3/8 of inch further apart - this valve works with out redoing the present plumbing.

Rated 4 out of 5 by from Mid-range jar top valve Residential grade/quality valve. Jar-top feature makes it easy and fast to take apart and re-assemble. Bushing between the solenoid and top-bonnet is nice feature to be able to open manually without getting wet. But need to cover in winter for freeze protection cuz if gets down below 26-28 degrees F, valve can get microscopic freeze cracks between the support ribs on the top-bonnet, which will leak slightly and cause water to pool and algae to grow on top and will continuously drip water off of the top.

Rated 5 out of 5 by from Good replacement I was looking for a replacement of an older Rain Jet valve and this fit the bill. It is a better product that the one replaced.
