MAIN WATER HEATERS. REDDY HEATER PART.
Main Water Heaters
- a principal pipe in a system that distributes water or gas or electricity or that collects sewage
- Denoting the center of a network, from which other parts branch out
- any very large body of (salt) water
- chief(a): most important element; "the chief aim of living"; "the main doors were of solid glass"; "the principal rivers of America"; "the principal example"; "policemen were primary targets"; "the master bedroom"; "a master switch"
- Chief in size or importance
Cheap tubing cutter works good
$7 tubing cutter is all you need. Did you remember to shut the main
water off first? In this case, the existing valve at the heater
was bad, so a smart cookie remembers to shut the main
water off too. Remember to open some valves in your sinks to relieve the pressure in the system. I like to leave the valves open until the very end of the job, during which another step (refilling the new tank) requires you have them open. You may nonetheless get a blast of water anyway due to residual pressure and gravity. Make sure you aren't wearing your nice leather coat when you do this, lol. Also DO NOT do this step unless the power is off.This cutter is cheap enough that you may need a pair of channel locks to turn the knob about 1/16th of a turn per "spin" of the cutter. I like to ream the inside diameter of the pipes out, as there will be a sharp ridge caused by the cutter's blade. The ridge shouldn't hurt anything, but it can cause turbulence and noise with moving water, so I like to use the end of something sharp, like tin snip blades or sidecutter blades or even just a channel lock's jaw, to ream the ridge from the inside of the pipe.
Finished the plumbing finally!
I used Viega ?" FostaPex (the gray lines), into individual ball valves on Viega's 8– and 12–position manifolds. The 12–position manifold is for the cold fixtures, and the 8–position manifold is for the hot fixtures in the home. The manifolds are connected to the main
1" water line (cold only, at the bottom-right) and ?" water heater lines (above) with Viega ProPress crimp-style press copper fittings. There is no solder at all in this picture. The blue box is a 60 ampere tankless water heater, Model 145, from S.E.T.S. Systems in Miami.
The tankless water heater is only supposed to be a point-of-use or supplementary heater, but it requires 60 amps, and provides a 50° degree temperature increase at 2.0 GPM. Since our incoming water is about 65°, I have plenty of hot water.
