    Bob, all of the ones I've used have been 24 volt.

    You're right. I checked mine and they are 24 V, which makes it easier to find relays.

    Thanks Bob for the info, the current timer I have is a cheapy rainbird, 4 zone timer, however, I will need to replace this with at least a six zone timer (with a motor circuit). Can you recommend a timer with motor circuit?

    I have an Irritrol SD-6 for $93.50. It has the motor circuit.

    O.K., If I install a sprinkler system using a well pump in a water storage tank I will need to do the following:
    1) Balance the pumps flow output to the individual zones (ie: 10gpm pump output to 8-10gpm out flow in the zones sprinklers)
    2) Wire the pump to the controllers pump start switch.
    3) Install a pressure relief valve in the system in case the zone valve does not open.
    4) Place the Well pump into a sleeve in order to create water flow over the motor for cooling.
    5) Properly design the system with correct piping sizes and valves, etc., etc.

    My question is, where do I find a pressure relief valve and at what pressure should I have it open at if my system pressure will be 55psi? I found irrigation pressure relief valves at www.fresnovalves.com but they seem larger than what I will need for my yard with my 3/4 HP (220V) pump (approx. 10gpm pump but not really sure yet).

    Also, where do I find a pump sleeve? Do they make these for this specific use or do you just Mickey Mouse a sleeve out of 6" or 8" pvc? Thanks for any help. Joe

    I have PRV's for $6.97 each. They are 1/2". You can get the 3/4" for a little more. The pump sleeve is a short piece of 4" PVC pipe.

    Sounds like you have a pretty good handle on what your doing. Let us know how it goes.
