It May Be A Good Idea To Turn It Off As Long As It Remains Near Full It Would Be OK. Just Incase Turn It Off. That Way The Top Element Will Not Be In Open Air( Not Covered With Water ). Which Will Cause It To Burn Out. Also When Water Is Turned Back On. Turn On The Hotwater & Let It Run To Remove Any Air That Might Be Trapped In Tank. Then Turn It Back On.
Not normally - without the water flowing from the meter, water cannot be consumed within the home, so the level inside the water heater will remain as it was before the water meter was turned off. It is common sense to remove power or shut off the gas to the water heater when another utility is shut down.
it could be from the hot water heater if it's not turned off. hot water expands pushing out more water when cool the heater can suck in air to fill the voide.
Yes, shut off water to entire residence if residence totally dependent on electric, including heat. If residence heated by hot water or steam heating system, water needs to be ON to boiler for heating system. Anything else that has water going to it can be turned off if it has a separate valve for it. Electric water heater should have power turned off and gas water heater should have gas turned off. Outside hydrant hoses should be disconnected.
There should be a shutoff at the wall where the water line enters the house. There may be one before the water heater or there will be one at the water meter.
Not unless the water line is cut on the cities side of the meter. Even that is doubtful because the meter should be one way and not allow house water to get back to the main line.
Standard meter will suffice, need to know pressure from meter to house. Size pipe appropriately for gas pressure coming into house X distance to water heater. Gas company or plumber should be able to help with this calculation.
It is probably right next to the water heater. There should be a shutoff at the floor, if not then at the meter is the most likely shutoff.
No.
Water heaters should be turned off, with the gas or electric to them turned off as well, when replacing any hot water lines. This would also be a good time to drain the tank and remove any built up water scale. This makes your heater more efficient.
Yes, as the day goes by and the heater and as well as the light are turned on they make the water "disappear".
Because the water heater is turned up too high.
Only if the hot water breaker is turned off.
