    How does electric sprinkler valve work?

    My entire response to rayh 78 did not appear in the post. Water pressure is required to open and close a valve. Electricity is just the automated way. Turning off the electricity will NOT open the valves. Note- Valves under water pressure will stay shut and (not to confuse things here) valves...

    How does electric sprinkler valve work?

    To rayh 78, Do you leave your water turned on? If you turn your water off, how do you know if the valve is open or closed??

    How does electric sprinkler valve work?

    First answer - How does the water get into the upper chamber in the first place? The solenoid stops the flow from the lower chamber lowering the pressure, the manual bleed releases water from the upper chamber thereby lowering the pressure.

    Want to add zones, but NO MASTER VALVE CONTROL BOX

    You have many unknowns here. Was the system installed commercially? Where on your property are you planning on adding zones in relation to where your existing zones are? Do you have enough pressure with adaquate GPM to irrigate to an extended area? How many of the smaller valve boxes did you...

    New install

    Extend the irrigation line past the last head. At that point install a valve box to accomodate a garden hose connection attached to the irrigation line. Using adapters, connect your air compressor at that point. Keep your air pressure at around 50-60 PSI for 4-6 minutes. This is only an idea. I...

    Is having more rotors and spray heads always a GOOD thing?

    You must have extensive landscaping in your front yard with such a high number of misting (fixed spray) heads. More often, most irrigation is done with rotating spray heads. Do stay away from the small rotors (20 to 25 ft radius) as they do seem to fail at a higher rate than the the large...

    Correct Pump to draw water from lake

    Have someone calculate the TDH (Total Dynamic Head) for your location. This is a combination of GPM, vertical lift, distance, pipe material, and pipe diameter. Talk with your local irrigation professional. He should be able to calculate the TDH and make a pump recomendation. It very possibly...

    New Sprinklers small problem

    The Rainbird 42SA comes pre-nozzeled with 3 GPM. You did not say how many heads you have on each zone. With 12 GPM at the source (where the water exits the structure), you should have no more than 4 heads on a zone if the pressure is adaquate. What is happening possibly is that the last head is...

    Zone Valve Trouble

    Did you get any dirt in the valves in the rebuilding process? Are all the solenoids screwed in tightly into the valves? Are all the manual bleeders shut? Disconnect the controller from the power source when you shut it down (eliminating an electrical, controller problem). It is a rare problem...

    Lake Pump doesn't suck water

    Help the pump out. After you have primed it also fill the lake suction hose also. If worse comes to worse, your check valve by your lake screen may be stuck shut.

    Turning on in ground sprinkler system for spring

    Did you try turning the water back on after zone 2 shut down? Sometimes the valves will just stick the first time...if you are lucky. Try cleaning the valve first (paying closes attention to be sure that the tube or passage way between the lower chamber and the upper chamber is open) and if...

    Watts anti-syphon valve needs replacing - with what?

    The Watts PVB may not be as old as you think. The do weather. The model you have in my opinion is one of the better ones made. Slightly more expensive than the Febco or Wilkins, but in the long run, better. The repair kit for the upper part (includes the poppet float, the bonnet o-ring and the...

    RainBird zone will not turn off!

    Rainbird, Toro, Irritrol, Hunter - all have similar problems. Other posters have addressed the obvious problem - the diaphram. Another possibility is an obstrution (sand, dirt, ect.) in the small passage between the lower chamber of the valve and the upper chamber. An obstruction would operate...
