Hot water not flowing to the bathtub
Hi everyone,
I have been scratching my head for most of the day.
Yesterday I installed a kitchen sink on the third floor of my apartment building/town house. Prior to doing any work I shut off the water to the entire house as there was no way to shut off the 3rd floor water supply only.
Today I learned that hot water is not coming to the 1st floor bathtub. The basement, 1st floor, and 2nd floor are all on one big boiler, or better to say two boilers where one's hot water exit pipe feeds the other's entrance pipe.
All of the hot waters, basement sink, 1sr floor kitchen and bathroom sink, and all of the second floor get hot water except the 1st floor bath tub/shower...
I have repeatedly checked all the supply lines and valves to find no reason why the water is not coming to the 1st floor bathtub/shower. It has its own supply line, every faucet/water source in the house is being fed separately from the basement where the water heaters are.
Any suggestions, ideas or guideline on how to proceed from here? I am stuck and do not know what to do.
I am only guessing one of the valves might not be opening up but I am not sure why would that be occurring and how would I do diagnostics for that?
Thanks. :confused:
