Water Heater Installation

So, your water heater has decided to retire and left you hanging. While this is a major drag, you can easily remedy the situation. If you want to opt for the professionals to install, that’s a great plan. However, this is something that you can DIY if you really want to. Loyalty Plumbing LLC wants to make sure you have all the tricks to do it right, so check out these expert tips for successful DIY water heater installation!

  • Know Your Heater: Step one is a no-brainer but get some background knowledge on the heater you have/the one you want to install. Learn the pros and cons of different model/types, understand what is needed to install it, etc. The biggest thing is to know the size and model of the heater you plan to install. This will depend on a few factors like family size, water usage, and such.
  • Get Your Tools: This is a job that requires a lot of tools and supplies. You’ll need a variety of wrenches and screwdrivers, pipe cutters, tape measure, safety goggles, Teflon tape, flexible hoses, pipe fittings, plumber’s putty, and much more…including the new heater itself. Remember that your safety gear is just as important as the rest of your tools, so choose wisely.
  • Shut it Down: Now that you’ve got the supplies, it’s time to turn off the utilities and allow the unit to cool, then drain the old tank. Once drained, disconnect everything and move the old heater out of the way.

  • Prep for the New: Once the area is empty, clean it up and make sure it’s ready for the install. Get the new unit into position, then get everything connected properly. This is where that Teflon tape comes in handy by ensuring a tight connection. If you’re installing an electric water heater, make sure you test the voltage to ensure the power supply is off before you try to connect that.
  • Fill ‘er Up: Once everything is connected and thoroughly checked, it’s time to fill up the new tank and test it out. Before filling the tank, let a hot water faucet run to get the air out (it’s ready when it’s a steady stream of water). Let the tank fill up completely once that’s done, then check again for any leaks. Make sure you follow the manufacturer specs for getting the utilities turned back on, then you should be all set!
