Multiport valve hiss

[drdrool]

had air leak in jandy valve, new seals fixed it. I prime great now, but I loose prime slowly when pump is off.

I listened carefully and hear a hiss coming from the top of the multiport valve (pentair 2' DE). I am going to replace the spider gasket. Anything else I should replace while I am in there that may be causing the leak?

Thank you in advance. All here have been great in answering questions and I have never once needed the pool store to come do work! (besides the closing and re-plaster reno)

Is any water leaking out of the multiport valve around the bolts or center below the handle when the pump is running? If so, numbers 20 and 23 in the following link may also need replacing.

If not, replacing the spider gasket only may solve the issue. Be sure to clean and lube the valve top o-ring (#20) before re-assembly.

I'll check on any leaks tonight. Thanks for the input.
