Leak in fresh water lines

[mtn_wife_530]

I have a 94 Coronado class A and it has a leak in a fresh water line somewhere between the kitchen and bathroom, possibility right above the tank drain. Can anyone tell me how to access that area?

It's a leak in the fresh water line, no doubt. It's the area between the kitchen and bathroom. The access under the stove is where the converter is. It's dry at the access under the kitchen sink and bathroom sink. Stands to reason, the leak is in that line at a point that's ran to to the exterior, near the toilet but there's no access.

It's not water from you A/C run off or morning dew or other moisture running down the coach?
If you go away for the day, disconnect from city water and turn off the water pumps do you see the same puddle when you return? Your post may have said that you can see a drip but I was not clear on that, sorry.
If you can see that, can you give us an idea of what is directly above the leak on the inside of the coach?

Try to get as many photos as possible of the general area. There are too many floor plans to just know.

I just don't know how to get to it.

No,it makes a puddle outside, I knew it was a leak.I let it drip onto a papertowel,it's clear and has no odor. I can see that it above the tank drain and feel that it's between the body and the interior wall.

Are you seeing water on the floor or under the coach? Are you assuming that because the water pump runs sometime you have a leak? The pump could have some grit in the diaphragm causing it to loose pressure at which time it will run for a couple of seconds.

If there is a leak in a piece of pipe, it would probably easier to run a new pipe and connect with Sharkbite connectors.

I have the bypass on for the water heater. It also leaks just hooked up to city water. I have no way to know what size the lines are. I've checked the Fleetwood site to no avail.

What size water line is it?
Cold or hot?
A diagram would be nice, but not too accurate.
Have you contacted the mfg?

Nothing inside gets wet,it seems to be between the body and interior, not at the tank. It causes the pump to kick in frequently. The leak is on the opposite side of the tank and pump.

I sure you have look and saw that the floor is setting on top of the tanks. The tank usually is larger than the door to get them out. Mirror and borescope is about the only way to see behind the tanks. the tank should hook up to the pump and then from the pump to the front /back of RV. The last time I help work on my friend it took us a half day to disconnect a bad line and pull the old one out and a new one in. He had to cut a hole 6x6 inches inside a cabinet floor to do the one end.

Is there any way to get a diagram of the plumbing and access points?
