Been toying around with this idea for 2 years. Finally decided to do it and was almost forced to do to a broken hand pump, which was worthless anyway. 2 replacements later and still no bueno. So last week I order a cheap seaflo pump from Ebay. 1.2 gpm, enough for me. I ordered the switch as well, which I've now lost.... Been poking around at faucets for 2 weeks and finally bought a bar/laundry sink faucet tonight and a bunch of extra hardware. The center spout is up fairly high and it easily removable for transport. I bought 12 feet of high pressure hose and got to work at 9PM tonight. Used a spade bit to drill my two holes: Tightened it down and installed the connectors. Cold for on board, and hot for city water. I figured humans are programmed to grab the cold water first. I had to chip out a little wood to make the sink nuts work properly. Soft installed the pump (it's not bolted down yet) and installed the hoses. and rigged up a power wire to the battery. Pumped right up and we had water!! Initially I was going to only hard wire it to the battery but then remembered the main switch would kill all power and thus solve my fear of accidentally bumping the switch.... I really don't want to run a power wire all the way back there. I'll have to see what I'm going to do. I've been wanting to add usb/12v power port back in that area anyway, maybe this is the time to do it. GRRR. At least I ahve working water, I may actually use my water for the first time. It's always just been so slow it was pointless. This sink is nice as it's got a hose end on it so should I ever upgrade the pump I can run a hose to it and wash hair or feet. Anyway thought I'd share my progress so far. I'll update this as I finish wiring, find my switch and bolt the pump down.
