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.
