This winter I want to upgrade to a pressure water system. I have ordered these faucets which actually look very nice for the head and the galley.

http://www.amazon.com/Ambassador-Marine-Trinidad-Collection-Folding/dp/B009LU7GXE/ref=sr_1_2?ie=UTF8&qid=1417863347&sr=8-2&keywords=Marine+Faucet

I am also considering adding a shower by the after ladder as we love to swim and that would be a nice upgrade. What is the best route to get the water line from either the head or the galley to the aft area?

Thanks

How are you pressurizing your tank? Is the C250 tank, hose, and fittings certified to handle the pressure?

You might want to instead consider an on-demand system, so you're just pumping out of the tank instead of pressurizing everything. But I don't think the faucets you've ordered are compatible with that type of system.

FWIW, for showering off I use a solar shower suspended by halyard.

I don't any indication he's planning to pressurize his tank, nor a reason that faucet isn't compatible with an on-demand pump. All it takes is something that turns on and off, and hoses that can stay pressurized.

Yes, I meant on demand system, pressure sensing.

I am not sure how a "pressure sensing" system works. My faucet has two wires that go to a pump. When you open the valve it supplies power to a pump that pushes the water. There's no "sensing" involved other than an electrical switch. There's no pressure in the tank, just a pump that turns on based on a switch in the faucet.

So what is a pressure sensing system? What pressure does it sense? Is the entire tank kept under pressure?

From my experience with pressure water pumps there is a sensor in the pump that maintains a preset pressure between the pump and the faucet. When the faucet is opened pressure drops in the water line between the pump and the faucet signaling the pump to start and attempt to maintain the pressure in the line. Some pumps, old PAR for example, have a pressure switch located on the outside of the pump. Others have a pressure sensing switch internal. I believe most modern pumps have an internal switch. The wiring for these type pumps goes to the DC panel and not the faucet.
The water tank is not pressurized, the pump pulls the water from the tank much as a bilge pump pulls water from the bilge.

Thanks for the explanation. That's different from my boat, which definitely has an electrical switch in the faucet. But your description sounds like how most others work. I hadn't realized that, but now I do. I had mistakenly thought that the tanks were kept under pressure.

Phil: that is a nice faucet, good find.

We have faucets that look like RO system faucets: Push for temp on, pull for staying power. They connect directly to our system, which has 1/4" OD Nylon lines downstream of the pump.

Sean or anyone else how do you route the water supply line from the front of the boat to aft for the shower. Also what the best route for the power line to the pump.

Hey Mac , I , T`d off under the gally sink drilled a hole from the cabinet to the bilge , then from the bilge straight back too under the stairs access then port to follow the bilge pump out line to the stern area ,then up to where you want it . i did a small hole first to check for clearance then used a hole saw and file to make larger and smooth ..under the cabinet there is less room .. under the stairs theres plenty of room for a 1 1/2 inch hole on my WK its a 2002
its pretty easy ...drill sideways not down :)

Hi Mac , you couldnt see the holes but on my hull 640 there was room for a 1 1/4 inch hole under the sink , and room for the same size hole under the stairs ..
I used a 1/8 drill bit to check the placement .
mirror and a flash light in the bilge

Hey Paul its a Simrad , it steers pretty good until it gets too lumpy out , i have had it now 6 or 7 years ..the belt broke a couple years ago i replaced it myself for $16

I replaced and ran all new water lines today, everything went really well, boy the old lines were shot. So another question. I want to mount the pump motor on the starboard side next the fresh water tank. I believe that will work fine, however I need to run power from switch plate down to the pump. this not so easy, I can't get the wire between the switch plate and lower cabinet under the sink where I can forward the wire in the storage area to the pump.
What am I missing, i can route the wire in the joint between the top and bottom from switch plate to the bow and back down or through the bilge.

I had the same issue when getting power from the distribution panel down to below the galley countertop.

I ended up drilling a hole in the aft side of the galley bulkhead and running a power line shrouded in wire wrap.

From there I ran it beneath the plate holders to a sub distribution block that I mounted on the forward face of the tab that is the aft bulkhead of the galley cupboard.
That distribution block provides power for our pressure wash pump (below the galley cupboard floor), Stereo, USB outlet and 12v Outlet.

I don't recommend putting the pressure wash panel under the galley cupboard floor.

Someone mounted theirs on the front face of the water tank, very nicely done. Basically they put a piece of ply strapped to the tank and the pump mounted on the ply.

I'm about to install a replacement speed transducer for my Raymarine ST40 BiData system. That's in the bottom of the V-Berth. I'm probably going to take the opportunity to remount the Pressure wash pump at the same time.

Paul, thanks, this is a real bummer. I guess I can tie wrap the the wire to the chrome bar that contains the gas line for the stove. So close but no way to get there.

Phil,
If you remove the cup holders from the back of the Galley Counter top, you might be able to fish a stout electrical wire from under the counter top, behind the cabin lower and upper liners to get to the distribution panel. (it beats trying to do it from inside the galley cupboard.)

You would need to consider chaffing of the wire, may not be a problem.
