Reducing Pressure

Kris_3 Member Posts: 24
We just successfully purged, but the pressure is higher than we started with...21 and we're concerned it could go higher...how do we reduce the pressure, we do not seem to have a pressure reducer valve by the fill...do we let some water out? Which valve? Thanks!

    Drain a little water out of the lowest drain valve you can find. It should not take much. Go slowly and watch the pressure drop.

    I saw in your other post that you though of lifting the relief valve. Messy and not as controllable. It may also allow some sediment onto the seat so may drip afterwards. Not absolute, just take note. Drain valves can be gradually opened.

    If the fill valve adds water while you do this, it may be set to high and thinks it has to maintain the 21 lbs. That can be set by a screw adjustment on top of it, if that is the case. Some need to be turned counter-clockwise. Turn it until any perceived (heard) water flow stops.
