I took out the mixer valve and tore it apart as far as I could into pieces and boiled it in vinegar/water solution for 30 minutes. Did not see much stuff come out and after reinstalling, did not improve the hot water flow.
I next decided to just hook up directly the bypass water line to the hot water line going to the faucets to bypass the mixer valve and the hot water tank completely. This definitely showed improvement to the faucets.
So I decided to eliminate the mixer valve completely and re-build the plumbing connections behind the tank similar to the way a Dometic hot water tank would be. I realize I will need to be careful because of the water temperature or change out the thermostat to an adjustable one since I removed the mixer valve.
Hope this clears up any confusion.
XT Models heat water in tank to 160*F +/-
W/O mixing valve that extremely hot (scalding temp) is available at the faucets
Unspecting/forgetting to properly temp water with cold can result in 3rd degree burns
WHY expose you/yours/guests to that chance??
Change out the T-stat
Optional Adjustable T-stat (replaces the t-stat...same location)
Just need to change the PIN connector on the BROWN wire to a Small Spade connector
Easy-peasy and NO Scalding events
