Let’s face it, most hot tub and spa leaks are quite obvious once you take the spa side panel off and take a look… (here we’re talking about most portable hot tubs that are outside, not in your bathroom). But slow leaks can be a real pain. Anyway, standard leaks are really easy –
The usual culprits are going to be:
- Pump Seals deteriorated due to old age, or bad water chemistry.
- Pump and heater union gaskets getting old and deteriorated.
- Heater leaks.
- Everything else.
The top three are easy and quick to fix. However, when faced with a really slow hot tub leak, let’s say one that drains down about an inch or two a day with no power applied, the problem can be quite perplexing.
There is one thing you need to have when trying to find a slow leak… patience. Then add in persistence.
The above shows a leak test performed on a roto-molded spa with limited access to the back side. No leaks were detected.
But the below photo exposes the slow spa leak culprit. There are actually two jets in this photo. The first is a Waterway mini-jet that is easily seen at the top. The second is a cluster jet enveloped in blue food dye that’s about 7 inches below it.
What happens is this… and you really have to look CLOSE and be PATIENT when you squeeze the dye into the water. The dye will be drawn into the leaking orifice. It’s akin to finding a virus or trojan on your computer. Only this is analog, not digital.
This spa was fixed quickly after 2 service calls, and we didn’t even have to cut a hole into the outside of the roto-molded plastic spa shell. The failure was in the jet retainer ring.. It was cracked.
If you’ve got a leak problem that just won’t go away, and you don’t know what to do then give us a call.
