It’s raining today and there’s not much I can do on the van without constantly walking back and forth to the shop and getting wet. I took this opportunity to redo the plumbing in the kitchen that I ripped out when I installed the gas lines for my stove and water heater.
I only made one cut in the line when I took it out, as the other two connections were serviceable connections that hooked into the water heater. I had to change the direction of the pipes leaving the water heater because my gas line is in the way now, but other than that, I didn’t have to do much else and was able to reuse the plumbing lines I ripped out before.
Then I added the insulation. Again, most of it I just reused from the stuff I took out before; only had to make a few adjustments.
One of the reasons I’m kinda glad I had to redo the plumbing was that I was able to add in a pressure relief valve. While watching videos on tankless water heater installs, one of them pointed out that it was required by code. In case the pressure in the water line builds up too much, the valve will open to relieve some of that pressure by draining some of the water out. Without the valve, if the pressure gets too high, it could burst the pipes (causing hot water to spray everywhere). Now, even though I’m building this in a van and my water pump is not supposed to surpass 50 psi, meaning I don’t think the water heater will ever manage to go above or beyond 100 psi, I figure it’s better to be safe than sorry. The white pipe going down will go through the van floor and drain any water directly on the ground.
It’s supposed to rain for the next few days. I don’t think I wanna go that long without getting any work done, so I’ll probably rig up some sort of crazy tarp contraption to work through the rain.
