Does Turning Off The Well Hurt The Water Heater?
I am currently in the process of switching out my water tank (from the well) because there is a tear in the side. For the next two days I plan on switching off the pump in the well so it won’t be stress the tear, and only turning it on when i need water. Will this hurt the water heater?
When I turn on the well from the breaker I normally hear weird noises from heater. Probably from heating up more water?

It can. The water heater must always have water in it while on. Opening a valve anywhere in the home can drain the water level to an unacceptably low level. Each time you turn off your well pump turn the water heater off also.

if you have a two burner water heater, if any water is used the upper heaters will be exposed, pull fuses temporarily
happened to me at the cottage, the weird noise I was hearing was the electric current surging thru from the upper burner, I eventually disconnected the upper one permantely
or could be like you said the water heating up

There can be several factors that can occur . if in doubt turn it off no harm no ohh s^!t . If for some reason you get a siphon draining the system it could cost you more time and money in unnecessary or preventable repairs, turn off the water valve at the heater too.

if you don’t let the water heater drop below the elements and leave the power on to it,it will blow the elements so if your gonna do this either trip the breaker to water heater or make sure it stays above that line,be better to kill the power

As long as there is water in the heater no. You might try turning the heater to pilot if it’s a gas heater. Electric I would turn both off at the same time,

Its fine as long as you shut off power to the water heater as well, don’t leave it on when you have the well shut off or you could burn out the elements.

If you turn off your well no water will be going into your heater so stands to reason none can be coming out.it will be fine if you turn it off or leave it on.

Turn your water heater off when you turn the pump off.

WOW, what a variety of answers, most of them wrong. Let’s start from the top, Roger has a fairly good answer, but you really don’t even need to turn off the electric or gas to the heater. Turning off and removing the water resevoir tank will in no way damage any part of the water heater, unless you leave a pipe loose that’s lower than the heater itself and the water siphons out on the floor. The only way water comes out of a water heater is when new water is pushed in through the cold side, no pumping, no water going in OR OUT. Perry, there are NO thermostats in water heaters to turn them off to avoid damage. The ONLY thermostats are for regulation of temps. There is a hi-limit fuse in gas water heaters that shuts the gas off completely if the thermostat/valve goes haywire and lets it get way too hot, but once it blows, it’s done. It doesn’t reset. The valve/ thermostat has to be replaced completely. Think, there are no such things as two burner water heaters, there are however, two element electric water heaters, with non-simultaneous upper thermostats, in which case, if you disconnected the upper element you wouldn’t get any hot water at all. William B and Ford guy, you’re both wrong, nothing will damage the heater unless he intentionally drains it from the bottom. Starr, best answer so far, and last but not least, Harry O, you’re also wrong. The only spigot in the house you could turn on that could possibly drain water out of the heater is the drain spigot on the bottom of the heater. Nothing above that will cause any difference in the volume of water in the tank.

Most water heaters have a built in thermostat that will turn them off before any damage.
