Here's the situation that's got me so puzzled...
The construction is a barn-to-house conversion that my grandfather remodeled about 25-30 years ago (slab on grade). And I'm not saying he "cuts corners," but at the same time he will look for the most "economical" way of doing things every time. Pipes are copper and PVC (that we can see).
Anyway, about 2 weeks ago we noticed the carpet in the bathroom wet (thought it was left over from a shower) but within two days we were ripping up the carpet/padding and shop-vac-ing about 10+ gallons of water a day. The water comes up through a whole in the concrete where the plumbing enters for the bathtub. Believed that it was coming from a problem below the slab. Finally got a plumber out by day 3 (Friday) who took one look at it and said they'd have to send a higher-up out...who didn't get back until day 6 (Monday).
The boss looked at it, first recommended we abandon the main line under the slab and run a new line from before the house, and through the attic. After discussion, we decided that they would come back with a jackhammer once we had demoed the tub and cabinets and find the problem under the slab.
Two days later, after more than a week of flooding and having done NOTHING, the water inexplicably stopped coming through the slab. Anyone have an idea about what could cause this, liklihood that it will return, what the...?????
