PF-50 Sand filters--help please

[GoGi]

Where do you purchase O-rings from? I have PF-50 and just redid the back yard (replaced concrete deck with pavers; drained, chipped and now waiting to replaster the pool) and I want to clean out the sand filter before refilling the pool. The PF-50 still works but I had been seeing a gush of cloudy water the first few seconds when it runs so I suspect my sand could be due for a change. I have owned the house/pool since 2012 but I am pretty sure the sand has never been changed for at least 15years.

Also, any suggestions of whether to go back with regular filter sand or use one of the sand-alternatives (aqualoon or zeosand)?

Sand very seldom needs to be replaced. It DOES need to be "deep cleaned" every once in a while. Here is a video for that: Deep Cleaning a Sand Filter We have had some people try out the zeosand and a couple the aqualoon and most of them said they would be changing back to sand as the other stuff just does not last as long and causes some problems in that it gunks up.

For the o-ring I would try Swimming Pool Supplies - Pool Parts - INYOPools.com They are my go to for finding hard to find parts and such.

Thanks!
When I opened the filter, the seal was in very good condition and I was able to re-use it. Just re-conditioned it with some silicon plumbing lube and it went back in just fine.

I also found that my filter had glass media rather than sand. Pool builder looked at it and said just a deep clean and I don't need to replace it. Since I wanted to see how the laterals were anyway, I emptied media out into a huge bucket and was able to give it a good wash as well. Lateral were very healthy as well.

Pool plaster was complete 3 days ago and still going through the low pH curing stages so I dare not turn on my equipment for now.
