Valve Tech / Re: Leakage
« on: April 10, 2013, 10:35:23 AM »
I have had a CSV 150 on my house/heat pump system for 3 years and it just started leaking a rapid drip at the flange. I snugged the screws but they were already tight-the valve continued to leak so I bought a new CSV 150. When I installed the new one it immediately had a slow leak in the same place so I again tried snugging the screws and that might have slowed it a little but it still leaks. The valve is installed horizontal and has black plastic pipe on a 90deg on the inlet and outlet and the alignment is good so there is no excessive force stressing the flange. Pump shut off is about 55PSI and I have a large expansion tank.
I disassembled the original valve and I did not find anything wrong-the rubber (seal at the flange) looks in good shape and is resilient.
This unit is in the basement and I don't want to have empty a bucket every few days-leaks about 2 cups per day. Are these valves prone to leakage? Any brain storms??
