Frozen Hot Water

[18CrewDually]

Yep. I can't figure out the schematics of it but there is a hot and cold right under the water control panel, and another hot and cold about 4 feet back in the proximity of the water heater.

The 2 in the back have valves or caps? They might be the fresh tank overflow.

They do have caps. There is pressurized water behind each one. The tank drain is next to the back ones. I'm thinking the front set has something to do with the nautilus system.

Oh ok. I was just throwing it out there.

Not sure if I should have low point drain envy...Probably not, as my unit hasn't had any freeze ups

I did make one mod to my hot water supply. My kitchen sink is right next to the HWH, yet it took a long time for hot water to make its way to it. The water line exiting the HWH went towards the front of the coach and another line fed the sink. I capped off that line, and put a tee in the line exiting the HWH to feed the sink. Hot water now appears at that sink after 1/4 cup runs.
This reduces wasted water and makes DW happy.

I have the exact same scenario on ours. I found the lines via a removable panel under the sink. In the spring I'm putting in a T and getting rid of the sink vinyl hoses. I already eliminated the water heater heater vinyl hoses. I figured easier to do it now before a leak ever occurs.
If only we waited for the 2025s instead of our 2024 to come out, they all now are metal fittings and no leaker vinyl hose.

My vinyl hoses were already gone DW wanted a better faucet for the kitchen sink first thing. Since she does the dishes, she gets what she wants.The vinyl hoses wer elminated during that project.
I was shocked at just how much water a better faucet saves.

Just had the same issue in West Texas this morning, both hot and cold not working. Heated the hot and cold low point valves under the control pane and got ice out of the valves/pipes and all water working again!
Thanks to all here for the info!
