Part 1: • Instant Hot Water Line...
Here is an update to another video I posted on this subject. If you do the mod, then you need to also do this one. At first, the hot water recirculation was working well. Then, I noticed it was not really coming out as warm as it used to. After I modded the brass valve with a plastic swing, I theorized it would be floating too high for a trickle of water at a spicket to close it. With the slow flow that comes out of the bathroom faucets, I suspected it was not enough to suck the swing valve closed and I was getting flow from the bottom of the hot water tank. Cold water enters at the base of the tank though a down pipe so when pressure is released by turning the hot water on, The cold water from the base of the tank back flows in the hot water lines through the recirculation pipe. One additional modification and now it works flawlessly. It now does exactly as it should: Floats open for conventional flow and and closes with the slightest trickle of water at the faucet.
