Loose Bleeder Screw?

    I had a zone today that would not come up but everything tested good from the clock.

    When I found the valve, the bleeder screw was leaking. I tightened the bleeder screw and everything went to work. I turned the zone on and off about six times from the clock and all seems OK.

    Does a loose bleeder screw keep the valve from opening from the clock?
    Sorry for this "rookie question."


  2. I wouldn't think so. What type of valve?

    Irritrol with flow control.

    Black plastic Phillips-head bleeder screw. Valve approximately 10 years old.

    Usually it's the other way around. The valve will not close while water pressure is being released from the top of the diafram. The bleed screw and the solenoid both do this.

    It may be about time for a new diaphragm assembly, if it's of the R204 type. Sometimes, the metering nut only partially cracks, and you get intermittent performance on the way to complete failure. If all the zone valves are the same make and model, you might consider replacing all the diaphragm assemblies in one service call.

    I agree with "Inspired" if the bleeder is not closed the valve will remain open on irritrol valves.

    That's what I always thought...
