water line problems-- need water line schematic
Yahoo Message Number: 102580
Hopefully someone out there can help me. I used my 93 RB for the first time this year and hooked up to shorewater.  I and ended up with soaked carpet from the end of the back ceiling vent all the way back to the toilet and cabinet.  The water pipes were not wet, nor was there any water on the drain pipes.  The water pump wasn't leaking either.
 I originally thought it was water from a rain that came in the vent, however  the carpet in the bathroom cabinet was wet and smelled like chlorine - I assume this was water from the hot water tank since all the other water from my sanitizing effort had been drained out.  I didn't notice the chlorine smell outside the cabinet- don't know if that is because the but that could be because the chlorine had evaporated or the water was from another source.
 After it dried out, I put water in the water tank to check to see if I could tell if there was a water line leak somewhere- I turned on the water pump- water came out all the faucets and it was pumping out the shore water outlet.  The pump kept running so there is a leak somewhere, but I can't figure out how all of a sudden the water pump now pumps water from the water tank out the shore water outlet-
 does anyone have a plumbing diagram for a Rear Bath?  I see where the shore water comes in and connects to a water line, I am not sure where that water line goes  If anyone has any ideas of what might of happened, let me know.

Thanks Lynn Engelman

Most likely the check valve housing of the city-water inlet has cracked. You'll need to remove the inlet to check that. If there is insufficient play in the plumbing to pull it out, you'll need to disconnect the inlet line from the plumbing 'tee' that connects to the rest of the plumbing network.

Thanks Steve! I didn't even know there was a check valve there.  That makes sense for what happened when I tested the water pump this weekend.
 Do you think that is also the source of the original problem when I hooked to shore water- I have to admit this is one time I didn't use the pressure regulator (although

If indeed this is the problem, go to message 102396 for a detailed account of replacing the city water inlet valve.

Lynn, I agree with Steve, it is most likely the check valve.  However prior to replacing it, work the check valve back and forth with a small tool at the shore water inlet.  I thought I had a problem with mine and was ready to replace the valve, when someone offered me the advice above.  Sometimes, sand, dirt or other debris gets behind the seal and can be worked out when you depress the valve a few times.  It is worth a try, saved me time and money on mine.

Probably the water pressure cracked the check valve housing. This is unlikely a failure on a new fitting, but they are only plastic, so age takes its toll...
