Situation as described in the question. We have a peer & beam foundation. I already went under the house to check for a possible leak. The bathtub pipes are impossible to get close to, but from about 6-8 feet away I couldn't see any signs of a leak, nor could I hear any water drip or squirt or anything. The hot water pressure on the bathroom sink, which is downstream from the tub, has always been weak but seems normal.
- Any ideas on what is likely to cause the lack of hot water for the bathtub?
- Should I keep running the hot water trickle, in the bathtub and the bathroom sink? Or should I rather shut off the main and try to drain all pipes?
Unfortunately, I can't access the 5 or so feet of pipes where the problem has to originate from.
Thanks for y'all's advice, Hannes
