Only Hot or Cold, Not Both in Bathtub
I have a tankless water heater. The water in my shower/tub, when turned on, only delievers cold water. To get hot water, I need to turn on the bathroom faucet hot water, then turn on the bathtub water. Hot water will now come from the bathtub, but only hot water--not mix of hot/cold. I do not have to keep the sink faucet running once I have initiated this hot process in the tub. I can not get both hot and cold in the bathtub. Also, the bath faucet did work at one time.
Called the plumber who called the tankless company. There was no hot water reading at the the themostate for the tankless when the tub water was turned on. The company said the problem was at the faucet. The plumber ordered a replacement kit for the American Standard faucet.
Still not working the way it should. Note, that all other faucets work fine in the house. The plumber said there appears to be enough water pressure to get the tankless fired up; but I still have same problem.
Any advise or insight? Thanks!
Stumped here, and not getting too far with my plumber. Two visits already and still not fixed.
