![]() Secondly, some parts of the yard may not drain as well as the others, and they’ll need less water. For one, an area of your yard in direct sunlight will need more water than a shaded area. Your lawns watering needs are not uniform. Fortunately, adjusting sprinkler heads is not a complicated task. One solution is to adjust your sprinkler heads to ensure even sprinkler spray. So what can you do to make sure the grass gets the right amount of water to thrive? But simply turning on the sprinkler system won’t help if the grass is not getting adequate water coverage or if all the water is spraying on the sidewalk. High moisture or high salt climates will accelerate this process resulting in shorter service life.A beautiful lawn is one of the most outstanding features of a garden. Since the relay is a magnetically activated switch, its contact points start to oxidize, making it ineffective at pulling together the high voltage contacts. A usually quiet pump starts buzzing while in operation: When the pump starts buzzing, it means the relay is on the fritz, and it needs to be replaced. Contact a contractor in your area to diagnose the problem and to fix it for you.ħ. ![]() If your controller’s transformer is too small to pull the relay contacts in, you need a bigger transformer to stop the problem. To stop the chattering, change the wire size to 14 gauge for runs over 15 feet. There is a chattering noise after you install the pump: The pump start relay may be too far away from the controller, and the wire size between the controller and the relay’s coil is too small. To investigate further causes and solutions, go to our FAQ page and look under “Indexing Valves.”Ħ. ![]() For instance, our 4,000 series require 10 gallons per minute (GPM) to operate and our 6,000 series requires 15 GPM. 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. You’ll need to contact a contractor to diagnose, locate and repair the suction leak.ĥ. If you have a pump fed system, there may be suction leaks on the pump intake line causing the pump to surge or not keep a steady flow of water for the disc of the valve to depress and stay in one zone.To fix this problem, move the indexing valve closer to the water source, so that the electric control valve or pump is closer to the indexing valve to pressurize the supply line. If the pump is located more than a few feet from the water source, the inside valve disc pops up and down, skipping zones as the supply line fills with purging air. ![]() Install a check valve on any outlet that has zone piping higher than the valve.
