Possible leak in built in hot tub (Next to pool on lanai)
 

Our hot tub has been losing a couple of inches of water every few days.

The tub is built in meaning no access to the exterior of the tub itself.

All outside equipment, filter, pumps, etc have been checked. New o rings installed on filter and pumps. No visible water anywhere around outside equipment.

I am guessing (hoping?) it is one of the tub jets.

Looking for input from any who have had a similar experience. Original installer, T&D Pool Construction coming to check it out next week (original installation 2006...all equipment maintained/replaced by T&D from day one).

Hoping to not have to start breaking up cement!!!!

Didn’t they cut square out and dig hole, line it and drop hot tub in? I would think they could have 6 to 8 men lift it out or Jack it out?

If jack hammers is ever in the equation it becomes a large planter!!!

Jack meaning some type of portable hoist.

You could try placing saran wrap (or similar) over the jets, the one that is leaking should cause the saran wrap to be sucked into the jet, the other should float away. As for repairing, I have no idea if there is no access to the outside plumbing, maybe you could have that jet plugged.

Jets
 

I can tell you from experience I am 99% sure it is a loose jet. Buy one of these for $6 and tighten your jets.
