Food Cart Project Part XXVIII: Plumbing Begins.

Having picked up the sinks and first round of supplies last weekend, I was able to jump into the plumbing side of things over the last few days. The first step was to install the water pump to the wall:

Next was to run the cold line from the fresh water tank to the pump:

And then to continue it from the pump to the T-connections which will lead to the cold faucets on the ware and hand sinks:

Here's how all of that looks from underneath, with the sinks and their counter back in place (if you look closely at the fresh water tank, you can see the "cage" I built for it out of 2x4s, which I then painted white; this is to help the tank keep its shape when full):

You might have noticed that there isn't any copper anywhere to be seen. I used what's known as "pex," which stands for cross-linked polyethylene. It's pretty much standard nowadays in mobile, as well as residential, plumbing applications. The connections basically screw on to the pex, and create a seal (other connection types include using copper compression rings, and expanding the tubing with a plastic "shape memory" collar that shrinks back to its original size).

After all of that was in place, I installed the door for the water:

Here's what that looks like from inside the cart:

The large hole will be connected to the fresh water tank's inlet with about 1-1/2" esophageal tubing, while the smaller hole will be connected to the tank's air vent with 1/2" tubing (the door itself, of course, not being air-tight). A piece of plywood, painted white and with a couple of holes cut out for the tubing, will finish it up nicely, and I'll get some of the insulation packed back in there.

Before I can go any further, of course, I'll need the tankless water heater and the gray water tank. Those are on order and should arrive sometime this week. So, by the end of next weekend, I should have some more plumbing in place for you to check out...
