A few more hints and tips, please? (pretty please, with a cherry on top?)
My 740 is apparently leaking out the flush vent. I have found pool water seeping out of the end of the flush/drain tube (across the yard) when the valve is not set to flush, and when I run the pumps to filter the pool this leakage increases and the pool water level falls fast.
I have found the data sheet at http://www.hayward-pool.com/pdf/manuals ... P740DE.pdf
Is there another website that explains the re-build process? Or can someone tell me which part of "the guts" I need to order?
My valve is some 15 yrs old, and probably should be replaced completely, but since I am presently unemployed I would prefer to fix this myself and save a few $$$$
Can anybody point me toward a bit more info on how to service this valve? Thanks ahead of time for your help!
