A few posts back I described how I installed an inexpensive diaphragm put in the van. I did it quickly, was keen to try it out on a trip. The other day I relocated it to what I think is a better spot.
I removed the in tank pump, the bilge pump type unit I was using as a stock replacement, and pulled the electrical wires out through the hr grommet at top of tank. I sealed the grommet wi a 1/4-20 stainless bolt and nut.
You notice that the little wall that separates the cupboard from the wiring has been removed. I, like many other owners, removed that wall early on to gain a little bit more cupboard room. To protect the wiring from shifting cupboard contents, I screwed on a bit of the cheap carpet I’m using as cupboard bottom liner.
The pumps is a bit quieter back here. Still louder than the in tank pump, but considering the increase in flow and pressure, the additional noise is really acceptable. And for goodness sakes, just how long are you going to have the faucet turned on? 🙂
There is one, or maybe two, more things I’d like to add the the install. First one I will certainly will do, and that is add a relay back up front under the sink. You see, the eurovan faucet wiring is pretty skinny stuff. It’s not a long run from where it connects to existing wiring, but I’d rather that the switch is not handling the full 2.5 A of pump draw.
The second improvement that I probably won’t get around to but would be neat, is a little pressure tank accumulator. It’s what’s used in other RV and marine installs. Not sure if I really need it and if I am willing to devote space to it, I’ll see.
