Home Depot!

Sometimes, in the very rare case, one can find perfectly reasonable, and sometimes ideal, applications for "non-marine" materials. You know, the stuff that does not include the "marine premium" in the price point?

Here, the freshwater tank fill plumbing is one of those cases. The fills for the three freshwater tanks have been plumbed with household PVC pipe and fittings (Schedule 40) including three ball valves to isolate each of the tanks. Much cheaper and easier to fit/install than what one might otherwise use (flexible hose, stainless hose clamps, brass/nylon hose barbs, bronze ball valves, etc). All this PVC for less than $20 at your local Home Depot!

For you international readers, Home Depot is an American retail building material supply chain of stores. Sometimes referred to as the BORG (Big Orange Retail Giant).

As for the plumbing, a hose from the deckfill will feed a valve assembly that will direct the fresh water to any one of, or all three tanks. Before the valves, a tee with an auxilary port is fitted to provide inputs from other sources (like a water maker). Tools required: chop saw, tape measure, PVC cement.

At this time, only the valve assembly is permanently glued. The pipe and fittings feeding the tanks are dry fitted until they absolutely need to be glued (in case I change my mind, ya know).

Actually, I lied. There are some "marine" fittings in that plumbing. Three PVC 90-degree street elbow fittings from Sealand (purchased from our marine supplier). These have shorter flanges and a tighter "turn" than standard fittings to help keep things more compact in smaller spaces. $2 each, including the "marine premium".

The observant reader will notice that, in the first picture, one of the plumbing lines runs OVER the floor supports.  When the floors go in there will be a small step there, extending the floor from the main salon into the forward salon by about ten inches, concealing the pipe (and perhaps other utility). This is by design (really!).
