I have not posted on this forum in quite a while, but I know you guys can help me out. My pool is 16 years old now and I have been having to replace a few things over the past few years due to age. My backwash valve, I believe, is contributing to D.E. getting into the pool. It is one of the push-pull types. Specifically, a Purex-Triton or Pentair 263064. It looks like this:DSCN2785 (480x640).jpg
The top of the valve where the screws are installed to retain the top plate is cracked, the handle is broke, and I have never liked the way it works. It is always next to impossible to rotate the handle and get it pulled up into the backwash position. Hence the broken T-handle. I've lubed, re-lubed and re-lubed and that is no help to this valve. It is just very stiff to operate. The cracks at the top are not going away either. I believe the cracks are letting air in when the pump is not operating and letting the water from the filter slowly drain back to the pool. I have had a problem with D.E. getting back to the pool for a couple of years now. So... I'm in the market for a new backwash valve and I want one that operates better than this one.
I'm thinking about this one: A Jandy 8034J DEL Series 2-in-1 Neverlube Multiport Backwash Valve with Pre-Plumbed Union Kit
Anyone have experience with this valve? Do you think I would have any trouble installing it? They have what they call a "versa coupling" in order to adjust the inlet/outlet port spacing.
