Hayward SP0410X502S Micro-Clear Slide Valve Assembly with 2-Inch Pipe Review

This is a copy & paste of my review of the replacement piston handle assembly that you will no doubt need eventually for this poor pool valve. See the original review here: [...]

Review:
I finally got fed up with my multiport valve having frequent need of replacing the spider gasket. So, I decided to switch to the simpler push-pull valve approach. I reasoned that I only really needed two functions - filter and backwash - and that a simple set of O-rings were more likely to last than the spider gaskets I had been dealing with. Well, all seemed good initially. But after a couple of months of use when I went out on a routine backwash mission, I was dismayed to find that when I returned the valve to the filter position, it started leaking water out the top where the piston slides through the cap. After a little investigation, I found that there is a tiny O-ring inside that cap that seals the water from coming out through that point. Unfortunately, it was so hard to disassemble the thing to find this in the first place and the prospect of properly seating a replacement O-ring looked so poor that I opted to buy a replacement piston assembly instead. I felt at the time it was my fault as the water quality had been very poor for a while and had contributed to early corroding of the steel piston tube.

However, I had (and have continued to have) my water in great shape when I replaced with the new part. Again, though, after about a month of use I went out to backwash the pool and the same thing has happened again! I have not needed to backwash much since I replaced this part as the water has been that stable and the filter pressure had not built up. I have not disassembled this newest piston, but I am confident it is the same issue. I am very disappointed in the fragility of that top O-ring and have to wonder how anybody has any success using this push-pull valve over any kind of significant time.

I will have to return to using a multi-port value. Although those have also been troublesome, they have at least lasted much longer than this valve before giving me trouble.
