Small Leak on Valve Fitting

[keenebean]

I have a very old (20+) years Garden Leisure spa. It's circular and only seats four people at the most. I recently replaced the GFCI plug receptacle successfully, but upon filing, there is a small leak from the pipe connection just before the valve. The water drips off the bottom of the valve, but is in fact coming from the pipe connection to it. See photos. I'm not sure what valve this is, as we no longer have the manual and information online is impossible to find, but it appears to be a gate valve. There's only one pump. Is there an easy way to patch this leak without replacing the valve? If I do have to replace the valve, can it be replaced with only PVC pipe and forget about the valve? Thanks for your help.

Often gate, or slice, valves will leak from the top where the metal shaft enters the pvc. Use a paper towel to verify that is not the case. If it leaks from there it must be replaced.

If the fitting in question is glued you could try epoxy putty. Just remember that surface prep is key to success with epoxy, and it is not a permanent fix.

If it is a threaded fitting, you can get a new o-ring.

Or you can try a fix-a-leak additive, which will make a big mess, might not work, and will leak again in a week or a year.

If it is accessible and there is a few inches of pipe on either side I would just replace it. That is a permanent fix and won't cost $50.
