Hot tub Leaks

Hello, We have an acrylic hot tub that sits inside a wooden siding. Underneath is a lot of foam insulation. We have a leak that is bad enough that we are no longer using the hot tub.

We thought about turning the hot tub on the side, removing or scraping off the insulation, and try to find the leak. Is this how we find it?

We used some type of caulking on a crack from the upper side, and that did not work. The motor and all electrical is about one year old. The shell is old though. So what do we do? Suggestions on how to find the leak? How do we repair the leak? We would even hire someone to repair it, but don't know who does that type of work.

Thank you for any help.

So you do know where the leak is on the top side of the tub?

I've worked on leakers up here in NJ but most were caused by leaving water in the unit or in the pipes with unit shut off in winter and then pipes split. You're in Texas, I doubt freezing pipes would be your issue. You need to determine what area it's coming from. Like insided the motor access area or near one of the side nozzles. You're right.....with the foam it's not easy.

so I read to put food dye in the water - just a small amount of water. Do not turn on the jacuzzi at all. then see where the dye goes through this foam. Still we have to turn the jacuzzi on it's side, and I guess that is normal.

Also, one of the jets needs to be replaced and I removed it to find the replacement online. Would that cause a leak?

I don't think it is related. We used the hot tub without any problems until it was "gently moved". It was unlevel and my husband tried to level it. After that it started leaking bad - like six inches per week or more. Always low on water -

You removed the insert or the entire housing ? If you removed the entire housing I'm quite sure that would cause a leak.

I removed only the insert and not the entire housing. Still read what I just posted about using the hot tub after I removed the insert - it didn't leak then.

well I guess I need to replace that jet first to see how much that is causing the problem. Still my husband thought it was a crack in the bottom or somewhere in the tub, because he tried using some type of caulk on it. I think the hot tub is worth saving since all the guts are new inside. Is there someone to call to fix this? or ideas on finding the leak? I can order the jet replacement. The inner part is still there. It was a large back jet on one of the seats fairly high up.

If you have a visual crack that would need to be addressed first. I've never had to fix a cracked tub but I'd guess it would need to be repaired from the bottom with some type of fiberglass tape and resin. As far as who to call to fix it - you pay the air fare to and from NJ and I'll come and fix it for you. Seriously you'll probably have to locate a local hot tube company that advertises repair service.


On edit......maybe when the hubby moved the tub it got racked, and twisted one of the water fittings causing a leak.

Yes I think this is the problem. Thank for offerring to service it. You might get an all expense paid trip from your Insurance company with Hurricane Sandy - we are in Austin, Texas. No hurricanes, no bad weather, sunshine and high of 70 degrees every day.

To find out where the leak is, let the water level go down until it stops. That is the height of the leak. If it fully drains, then it's underneath. It could still be a fitting, but the lowest one above the water line.

We have the very same type of hot tub ( a Beachcomber), and after it started leaking a couple of years ago, we found a product called Fix-A-Leak which circulates through your hot tub's system and plugs holes of up to 1/8" (if memory serves). It took a couple of applications, but it stopped the leak completely and it's been leak-free ever since.

I'd be concerned about that 'fixing' something that isn't a leak....

I understand your concern, but this product is specifically for use in pools and saunas, and although one should never assume anything, I feel comfortable in my assumption that it would be engineered not to damage any of the unit's other components. And since they say proof is in the pudding, my pudding's been leak-free for a couple of years now, and that's including some pretty harsh eastern Canadian winters.
