Water Lines in CD25 - Anyone Replaced?

Pat Anderson

i would like to replace the two water lines that used to be hot and cold leaving the water heater all the way around to the faucets on the sink with a single new water line, cold only of course, that would then tee to each side of the faucet. Actually, I removed the water heater and ran the hose from the water pump to a tee that has both the former hot and cold lines attached. The last place where these hoses are visible is under the inside step down from the door. They don't reappear until they emerge from behind the head. My reason for wanting to do this is because there is a leak or leaks somewhere such that if the water pump is left on for any length of time, the cabin floor fills up with water - NOT good!

Anybody have any idea how to do this?

Thanks!

Pat, when I removed the water heater, and put in the on demand heater under the sink, I replaced the cold water line, it runs under the head floor, in my 25 it was forward of the shower drain (which goes to the sump box under the port side having locker.

I just attached the new hose to the old hose, under the step, and then pulled the old house out--no connections under the head--the only connection was under the step, and then near the sink. I would put your T near the sink, where you can get to it easily.

I pretty much did the same as Bob did, when I pulled out my old 6 gal RV water tank, and replaced it with a 2 gal under the sink. My water tank is in the cockpit bilge, and the lines run along the port side of the bilge, then come in thru the "closet" floor on that port aft side of the cabin. Then they run under the door step, under the head, and through the bulkhead to under the sink. I only replaced part of the hoses, and maintained hot and cold lines under the sink. Most the hose I removed was the hot water hose at the old 6 gal tank. If you are removing all hot water, I would think you could just pull the old hot water hose after it's disconnected from the heater tank. Finally, are you sure the water is coming from a hose leak, and not from under the bulkhead between the cabin and bilge? I was getting water from the bilge leaking into the cabin, and at first concerned it was a hose leak. Also, if it was a leak from your water hose, you would hear the pump kick on and off? Colby

Pat, I can tell you one thing.....but then it's pretty obvious, I guess.

When I did all the work on my water system in the galley a couple of years ago (installing homegrown recirculating hot water), I confirmed that all the hot and cold water used at the sink and in the shower come from just one 1/2" hose for each that leads into the under-sink area of the gallery. All tees etc were after that, and easily accessible under the sink.

I suspect that the only tees before the under-sink area are easily accessed in the area where the hot water heater normally is.
