Why do 2 sprinkler zones come on at once?
5. Water is coming out of multiple zones at the same time: For the valves to stay open in one zone, while shutting outlets in other zones, there needs to be a minimum amount of water pushed through the valve.
How many sprinkler zones can I run at once?
Yes, it is often possible to run two valves at once. However there are several problems that can occur. You must have a sufficient water supply for both valves to run at once. If the performance of the sprinklers suffers and you start seeing dry spots in the landscape, you obviously don’t have enough water.
Why are all my sprinklers running at the same time?
A. This is a common problem when restarting after your sprinkler system has been winterized, or after the system has been turned off for an extended period of time. It also often occurs with brand new solenoid valves that have just been installed.
Are sprinkler zones connected?
It is connected to a set of valves that regulate the flow of water into a specific “zone” in your sprinkler system. The valves are tied directly into your water system and act like faucets that turn off and on when told to by the controller.
Should solenoid be on or off?
Avoid over-turning the solenoid in either direction, as this can cause damage to the components or cause pressurised water to escape the solenoid. When you hear water rush through the device, it’s easy to tell that the valve has opened successfully.
Does each sprinkler zone have its own valve?
An irrigation system is typically divided into several zones, each of which feeds sprinkler heads in a different area of the lawn or garden, and each zone is controlled by a valve that receives signals from a centrally located controller. Often the valves are located inside one or more in-ground valve boxes.
How many sprinklers per zone do I need?
Calculating Zones Each zone should include plants with the same watering needs, or an area of the lawn. Then, add up the necessary flow rate in GPM of all the sprinkler heads, divided by the GPM of your water supply. The resulting number will equal how many zones you need.
Why are two of my sprinkler zones not working?
A lawn sprinkler system is usually divided into two or more zones that water independently of each other. Each zone consists of several sprinkler heads controlled by a valve that is electrically activated. If a single zone is not working, the problem is usually an electrical issue or a defective controller or solenoid.
Does each irrigation zone need its own valve?
Why are multiple sprinklers running at the same time?
The sand got into the diaphragms in the valves and blocked the little pin holes that allow the valves to close. That, combined with lowering the water pressure slightly, would not allow the valves to close. Thus, multiple stations would be running at the same time.
What to do when irrigation zone comes on at same time?
Check to see if there is water leaking from anywhere on the top of the valve while the system is running. Hand tighten. First, unhook the wires from 4 of the zones. Turn on the other zone, if they still all come on, it’s the valves.
How many zones does a sprinkler system have?
The wiring for the control box has 7 zones plus a common wire and a master valve wire. I’ve checked the pressure at the well booster pump; it was at 63psi, and I lowered it back down to 50-52psi, which is normal city water pressure, I’m told.
Can a sprinkler system work if the ground is weak?
If the ground is weak or broken the zones will not work. The solenoids must receive power to open so need both a good positive and negative/common. All of the grounds/negatives are often tied together to one wire and if it’s broken you’ll find that none of the zones work.
