Hayward s200 leaking bulkhead union

[Kcbpool]

We have a leak from the o ring on the outside of the filter at the bulkhead union of the water return (I believe - the bottom pipe). Is it possible to replace this o-ring without opening the filter? Any assistance/instruction is appreciated.

Can you take a picture of where you are talking about? I have an S244. Not sure how different it is, but there's no o-ring right at the valve fitting. It it just a union added along the plumbing close to it? If so, you can replace the o-ring in those easy enough.

Hi, welcome to TFP!

If it's leaking from the spacer area, have a look at this thread: Replacing Side Mount O-Ring Spacer

And a link to the filter diagram in case you don't have it....

Personally, I'd open the filter and move the sand away from the pipes entering the filter. Then take it apart - clean inside and outside mating surfaces extra good and replace the o-rings, etc. After that, you may want to consider - Deep Cleaning a Sand Filter - since you already have the filter open.

Thanks for the assistance. According to the diagram, I believe it is part 23, on the bottom, that needs replaced. Not sure if that is the same as the spacer.

And thanks for the info on deep cleaning the sand.

Part 23 is the o-ring. Your filter doesn't pear to use a spacer.

Your filter is slightly different than the one in my first link above. I just provided that link to give you an idea of what might need to be done. The important part is to clean the mating surfaces well. One grain of sand could cause it to leak. That's why the recommendation to open the filter and moving the sand away from the piping.
