CHANGE PUSH/PULL TO MULTIPORT BACKWASH VALVE

[gbski]

Can I replace a multiport backflush where I have a push/pull on the same filter? I have a 36 SF grid DE filter with the push/pull valve which is currently all jambed up. Would like the vacuum to waste feature possibly.

Thanks!

You should be able to do that. What filter (make, model) do you have?

Mfr is Andrew's Advantage. Probably circa 1994 when pool built. Not sure if there is a model # - dark in there... Thanks

Tried to take out the piston to replace O-rings. Could not get the dang this out no matter. So I'm back to looking at replacing the whole backflush valve and the MPV again... The filter model # wore off the tag. The push-pull valve label is a Pentair 26-1165. Can I put a Pentair 26-1055 MPV in as a replacement. I have the 7.5" center and 2" pipe connections.

Thanks,
Gbski

Any MPV should fit if it's 2" ports and 7.5 on center. (mine is a Pentair MS 203 and has those dimensions)

You will surely have to re-plumb the intake (from the pump) and output (to the returns) plumbing.....I don't think you can match those up switching from a push-pull to an MPV
