Can anyone help me with this problem?
We have a spa bath in a first floor bathroom of our 2 year old home. For the first 18 months (and about 8 uses) there were no plumbing problems.
Then, after the spa was used one night, bucket loads of water started dripping through a light fitting in the ground floor ceiling soon after the spa began draining. A plumber was called immediately. After drilling a series of 5" holes into the plaster ceiling, he was unable to find the source of the leak - although it was obvious there had been a big one. After filling the spa and emptying it twice he was unable to dublicate the problem. In the six months since, we have used the spa another 6 or 8 times hoping to repeat the problem ... but to no avail. Dry as a bone!!!
We want to have the ceiling repaired but until we work out what went wrong we cannot proceed with surity. Any ideas what the hell happened and what we can do to be sure that it won't recurr???
