Not if the water heater is electric
Gas water heater has an orifice for main burner and for pilot light, if not electronic ignition.
No. The Main is source of water for that as well.
No.
you could buy a new one ? or call a mechanic ?
Water is coming down from upstairs or it is back pressure from the water heater. If it is the water heater, it can come out of either side of the faucet.
Example is ,an electrical heater connected to a main switch and the heater is placed in a bucket filled with water.
Central heating systems usually heat on a different system from the hot water heater, unless the main heater is a combination furnace/hot water heater. If this is the case, it could be because the outflow of hot water is greater than the ability of the furnace to heat the water.
Electric hot water heater is used to heat cold water for use in winters. Electric hot water heaters heat water faster than the ones which consume fire in order to heat water.
No, with the main shut off, no water can be taken from the heater so it will just sit there.
To replace the TPV on a water heater a plumber will have to buy a new one. After switching off power from the mains and closing the main tap, the plumber can then replace the new TPV .
Reason for question: Plumber left valve open and flooded house The hot water (heater) tank is fed from a 'header tank'; normally in the loft space but can be combined with the main heater tank (fortic). The header is filled from the water main. Unless the header is drained or its outlet is closed off, it will drain down through the open valve of the hot water (heater) tank.
As long as the water doesn't drain out of the heater somehow, no. What kind of car are we working on...
