Welcome to our forum.
And to say don't buy a well insulated tub next time so you won't have this trouble is ridiculous. So buy a non foamed in tub and spend twice as much on power to run it and have it last for 10 years less. Yep good plan.
I read it as sarcasm... and find it a bit amusing
Appreciate all the replies. Here's where I'm at so far. I have discovered even more leaks, around 10 in total mostly the same kind of leak I initially described, including a nail that was driven through a section of flex pipe! The things you find when you rip something apart! There is a massive amount of foam to get through and I have to figure out how to put all the wood skirting I've cut back together. Its a huge pain but its gotta be done. Can't deal with leaks in the middle of winter with subfreezing temperatures almost everyday for 5 months. My plan is to seal around every join I can access with a special PVC sealer/epoxy I got from a plumbing store made to fix leaks and even seal the ones that aren't leaking that I've exposed to preventatively stop any future leaks. My tub doesn't have a ton of jets so I'm probably addressing almost half of the joining sections, so I'm hoping that will work. I am running out of time as winter is approaching here in Canada so I need to act fast and need to go with the repair that is the most effective but at the same time the least time consuming. As much as I would like to completely overhaul the plumbing, as I know that would be the proper fix, there just isn't enough time and its not worth it for an old tub either I feel.Once I'm done with that I need to figure out how to replace the foam I've torn out. I want to use the same type that was in there which was a closed cell spray foam but its expensive. Any ideas/recommendations how to replace foam you've torn out?
And what if there's a disagreement over how a repair is done? If one pro through experience, feels plastaid is a hit or miss bandaid, how should they respond to someone suggesting it? Should someone spend 20 minutes of their time (which they're NOT getting paid for, BTW), typing out a FULL explanation about their knowledge, experience and why they think it's a mickey moused repair?Personally, I think it's a mickey mouse repair, that may or may not work, on a spa that was made during a time when PVC glue was known to be bad, where even now, more and more leaks are being discovered. Would I use plastaid? Sure, if it was going in an area that could be constantly monitored. In an area that's going to be refoamed, sealed in and and hidden? NO WAY IN HE%%! There are some people that firmly believe, if you're going to do it at all, do it right.
