Water leak - need plumbing diagram

[RadRik]

I have a 4 seasons 2012 FR Wildcat Sterling that I got as a leftover model after an RV show. The dealer has since changed hands. How do I find the plumbing schematics to help me trace a leak? I don't want to just start cutting the underbelly until I know where the plumbing runs.

You won't find any diagrams

[bikendan]

Doesn't exist.

Thanks for the response. I was hoping the manufacturer would have something. I didn't know how to contact them.

I doubt anyone you talked to would have a clue as to how your unit is plumbed.

Does it leak during a shower, washing dishes in the kitchen, outside shower?

I realized there was a leak when I heard the pump cycle every couple of minutes when I wasn't running any water. I've located the general area of the leak to a hot water line that runs from the tankless water heater to the
other side of the camper, but it runs between the subfloor and the bottom insulating panel. There is also a 'T' in this area that goes to the kitchen sink. None of the fittings seem to be leaking so I suspect a line is cracked and the floor where the pump and lines are showing is dry.

Doubt their is a crack in a line. I wouldn't go cutting just yet. I had a similar problem, found it by laying and wrapping toilet paper. If the pump cycles every couple minutes, I would start at all faucets. The drip is likely very slow like a seeping, or a toilet valve not fully shutting off (again seeping). Don't forget the water heater relief valve and all areas of low point drains (external). Happy hunting

A frozen water line over winter????

[RadRik]

Yes possibly a frozen line. I blew out the lines in the fall but some water may have settled in the lower sections of piping.

[RadRik]

I checked all the obvious places like under sinks, toilet and around the pump. I think I have it narrowed down to a section that goes under the subfloor from one side of the camper to the other. The problem is that I have to cut the lines and pull through or cut away the shield underneath to access it.

Before cutting the subfloor might want to check the check valve in the pump. Could be something stuck in it.

[RadRik]

Water is dripping from under the camper. I was hoping it was the pump, but it isn't.

[donanddona]

I wouldn't go cutting yet. You might be able to lower the bottom belly on one side to view the framing. This could keep the alignment of that subfloor.

[RadRik]

I will try that donanddonna. Hopefully the screws will back out ok.

If you pressurize the system with 30 psi air, you might be able to hear and narrow down where the leak is......I would by-pass the water heater for this test so it takes less time for air to leak out.......

[RadRik]

Thanks to everyone for the replies. I think I may have found the leak. I found an access panel to the pump and tightened all the fittings around the pump. I turned the pump on for an hour and it did not cycle one time. I traced all the lines and found a small drip on one of the drain lines which may need tightened up or resealed. I will check it again today to see if it lost pressure overnight.

Oh brother...I just read the message I posted. Not sure how the word porn got in there! It is supposed to be 'for an' not porn. A smart phone is a dangerous thing in a dumb person's hands.
