push pull valve

[rotenka]

I have leaking Pentair push pull valve and just purchased an O'ring kit for it. How do you get it apart to replace the small O'ring at the top?

Thanks in advance for help.

The top under the handle unscrews. It may take some force to get it to move.

Got it. I already had the cap unscrewed and the stem out I needed to get the small O'ring off and replace it. You have to bang the roll pin in the handle out with hammer and punch to get to it.

Glad you got it figured out. Sorry I didn't realize the specific one you were asking about.

I have a similar issue. Pentair Nautilus FNS DE filter with a push pull valve has a leak--kind of a dribble leak coming from the top. I bought the replacement O-rings and got it back into place. Still leaking! I'm guessing that I installed that really little O-ring incorrectly. The bottom 3 are easy to replace, but I didn't even see a top O-ring (hence the leak) so I had to guess where it went. See the pictures. Once I replaced the bottom 3 O-rings and put the push pull valve back into place, I unscrewed the top 2 screws and took off the handle part. I had to wrap the O-ring around all the things until it ended up sitting between the handle and the flat surface. Is this the correct place? The water is seeping through that area still. BTW--I did use the lube on all the O-rings.

Please let me know if anyone can help guide me -- it's the first time I've ever changed any O-rings and thought I did a good job.

No if you drive out the roll pin and slide the shaft out you will see a groove in the top cap where the little O-ring goes.
