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 ...

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 ...

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 ...

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 ...

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 ...

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? ...
