Changing an element us not difficult. Turn the power off. Turn the water to the water heater off. Drain the tank. Some models require a special wrench some a crescent wrench will work. Unscrew the conductors that attach to the element. Unscrew the element. If it comes with an O ring a very light coating of vegetable oil on the O ring will help it seal. If it ...

Pilot light thermocouple or valve controller. Cheapest one to try first is the pilot light thermocouple. All the box stores and most hardware stores have them.

You should test the output of the thermocouple with a multi-meter to confirm that the replacement is working as expected. An 8-year old heater would have an "auto-reset" thermal cut-off switch built into the pilot assembly, to protect the burner compartment from overheating, these can go bad. Was that replaced when the thermocouple was replaced? For modern ...

You could use either an on-demand water heater or a standard one if you want to keep 20-40 gallons of water hot on hand. The big thing is they will not run as hot as a boiler. However, running pex tubing in concrete doesn't require the water to be as hot as perimeter or radiator hot water heat as long as you leave it on long enough to heat the concrete up to ...

Water heaters only need to be raised (per code) if they are using an ignitable fuel source (gas, propane, etc). And even then, the code is that the ignition mechanism is what needs to be raised. If your water heater is electric or a heat pump, no need to raise it per code. But if you WANT to raise it then you certainly can, though building something is ...

As @Tester101 points out, IRC P2801.6 sets the minimum when you're installing an ignition-type heater in a garage. In other situations, here are two things I consider when installing stands for "classic" tank-style water heaters: We have hard water in our area, so it is nice to drain the crud out of the tank once a year. Having the water heater off the ...

re: "Can I just make one with 2x4 and plywood that's only 4" tall, basically just enough to be able to drain water off the drain tray? Or does the code require it be higher?" I imagine you 'can' do that, but I wouldn't recommend that you do that. I recommend you do the following: 1. Contact the Building & Code Enforcement office in your location to ...

Regardless of code, I like to get them off the floor just in case the basement floods. My preferred (and easily available anywhere) solution is a few solid concrete blocks; one under each foot. You can stack them if you want, too. This is an easy way to increase the height in 4" increments. I don't suggest using lumber. If your floor is the least bit ...

Check the manufacturer's installation instructions for the heater. As far as I'm aware, a gas appliance only has to be raised off the floor if there's a possibility of flammable vapors being near it (e.g. in a garage). IRC P2801.6 Water heaters installed in garages. Water heaters having an ignition source shall be elevated such that the source of ...

Q1: Should there be an (emergency) power switch next to an electric water heater? Doesn't have to be, but we always have a disconnect switch by water heaters for any commercial building. Q2: If A1 is no, is it okay to have one anyway? Yes, it's fine as long as it's wired right and such. Q3: If A2 is yes, what kind of power switch should I use? ...

As per [this link][1], I need a double pole power switch [1]: http://waterheatertimer.org/Install30As2.html this link

If you want a "switch" near your water heater, you should probably use a "SPA disconnect panel", rated for the circuit amperage or higher. There is no need for fusing, circuit-breakers or GFCI in the disconnect so it can be pretty cheap. An example would be Home Depot link

Our water tank/heater was fitted in 1968 and the previous owner didn't even switch it off once in the past 27 years. Still get piping hot water even after 6 people showering so I'm loathe to replace it with an undoubtedly inferior modern equivalent. The tank is in a drained basement so no biggie if it does leak and on that basis I'll not replace it until ...

The piezo spark has no real current just high voltage so there is no chance it can damage the material around it. If the one you found will fit and the spark is in the gas flow you should be golden.
