I have a leak in my fiberglass spa. The spa is separate from the pool, but shares the same equipment- pool does not appear to be leaking.
I suspect a pressure side leak due to greater loss when the pump is running. All plumbing lines not under concrete decking have been dug up- no leaks.
When I drained the spa I found one of the jet’s plastic gasket askew, see pic. Can I remove the jet ‘covers’ some how- the part the arrow is pointing to? On the other side the jets are set back further and on the grey ‘ring’ I can see threads, so I’m thinking these may unscrew. They are not moving easily though, and are 24 yrs old so I have been hesitant to force the issue not knowing how they might have been put together originally. There is a gasket of some type between the spa shell and the white outer ring/covering.
I would like to
1) obviously fix the gasket (how wonderful if that fixed my leak!) and
2) if I can get to threaded plumbing I could seal off the spa and confirm the leak is in the filter plumbing because
3) there are lots of little holes on the floor and seat that air comes out of- I suppose it’s possible I’m loosing water through these.
Thanks in advance!
