Work has been slow for the past few months, but I caught up with all the other threads that Iíve neglected and it gave me a boost of enthusiasm. For the past couple days Iíve been working on the fresh water plumbing and shower drain. When I used a hole saw to cut the hole for the drain pipe, I had to be careful to not hit one of the lateral i-beams that are spaced about ten inches apart.
I screwed into the floor to find the underlying i-beams and thought I had found the ones on either side of where I wanted to put the drain hole. After cutting through the 2x4 bottom plate of the shower wall, I thought, ďLet me check again ... just in case.Ē Sure enough, there was another i-beam under the floor. Apparently, there are two beams
right next to each other here. Since I hadnít yet cut through the flooring, I could simply move forward a few inches and cut. This does add a complication: Iíll have to adjust the location of the gray water tank under the floor. Not a big deal, but itís an annoyance.
Something for you to envy: My floor construction. The disk (1) is the plastic (maybe fiberglass ... whatever it is, itís very tough) sheet that covers the entire underside of my bus. It protects the layer of foam insulation from road debris and dirt. The insulation (2) is sprayed in between the i-beams that support the floor. Itís between 1Ĺ and 2 inches thick. The floor itself (3) is a layer of ĺĒ marine-grade plywood topped with ľĒ plywood.
Hereís a shot showing the i-beam under the floor. Close call.
Once the drain plumbing is mounted through this hole, Iíll foam around it to keep out the elements and hold everything in place.
I needed to at least test the fresh water plumbing for leaks before I finish the shower, so I connected the garden hose and applied pressure. Immediately found one connection that I failed to cement and it sprayed a bit of water before I shut off the pressure. Fixed that and then found two small leaks elsewhere, including the NPT fitting at the inlet connection. Fixed all of this and re-applied water pressure. Good to go. Wired the water pump and it works, too. Until I get the rest of the plumbing installed, Iím only able to recirculate the water in the tanks, but at least I know everything works. Now I can finish the shower and once thatís done, the side walls will support a lot of other stuff including the wardrobe over the water tank platform.
Oh, and I installed a third LED ceiling light. Lots of light in there now.
