Water Heater Piping Installation
I have a new normal, 19-gallon electric water heater. Installing a simple question …?
Is it enough to simply install (just) input cold water in pipes High, (just) out of hot water pipes above, the discharge line pressure relief valve, and put a drain pan under the heater? Or am I missing something? (I already know the wiring part.)
I did the installation and repair of these things for 35 years, and the only thing I can see that everyone left is a stop valve on the hot side and the cold. If you intend to live here for a great length of time, chances are you'll end up replacing the unit at a time in the future and as long as you have outside, it's much easier to install the valves now that you wish to subsequently. Plant valves on both sides allows you to completely close the water without stopping the whole house, and you do not wind with a bucket load of water on the floor of the line wants to drain when you remove the heating pipes. Also, I highly recommend ball valves. They are a direct passage valve with a stainless steel ball, set in a Teflon cage, never leak, wear out, open and close easily.
