YouTube Video Index – A list of all of my videos:https://poolmandave.blogspot.com/2014/03/swimming-pool-tips-reviews-how-to-video.html
In this video I show you how to fix a leaking or stiff push/pull backwash valve commonly found on most D.E. and some Sand filters. The hardest part is removing the piston as the o-rings tend to expand with age and lock the piston in the valve – making it difficult to pull it out on occasion.
I usually will order the complete backwash kit in case I need the other o-rings for the handle part. Plus it is sometimes cheaper just to buy the complete kit:
Hayward Filter Slide Valve 2″ SP410X Rebuild Kit
Pentair PacFab 2″ PVC Slide Valve O-ring Kit
Zodiac R0442100 Rebuild Kit Replacement for Zodiac JandyBackwash Valve
