water in our round bathroom vent

[Mark and Pamela]

Hello we are newbies here. We just bought a 2007 3000rk. While getting it ready for full time living we noticed a gurgling sound in the heat vent in the toilet room. I have not washed floors yet. Don't know where this is coming from. Ideas??

If it's a floor mounted vent I would suspect water in the vent line. Is air coming out of the vent?

[Mark and Pamela]

Some air yes, is it condensation?

My husband unhooked the air heat duct and drained the water out it was about a quart of water. Just curious what it was from. Now the heat blow strong and there is no gurgling.

I would keep an eye on it to see if the water returns. It could be left over from the previous owner and some mistake or flooding they had. The only obvious way for water to get into that chase is from the floor vent. Maybe the toilet overflowed or the back flow flusher leaked (all common problems). If it is new to you then be alert to ensure it is not a re-occurring issue.

Thank you yes we will keep an eye on it. I appreciate all the help!!

Run the backflush for a while. They are notorious for the backflow preventer leaking. My 2013 has it under the sink, but my 2006 had it in the wall if I remember correctly. The wall one had a cover about 8 inches square on the wall for access.

If the vent line was full of water I would suspect that water traveled further and gone into the heater plenum box. In our trailer it would be possible for that to happen and should also be drained. Your layout may be different.

Thank you! I will check those thoughts out. I appreciate your help everyone.

I think they may of had a toilet leak at one time, keep an eye on toilet leakage and " ALWAYS" turn off the water to your rig if you are going to be gone for more than a hour.

I would poke a hole in the low point so that any new water has a place to drain. A little parasitic heat loss into the belly probably isn't a bad thing. If you are using the furnace, it is probably cold out and you want to get some warmth to the belly anyway. Finally, whenever I clean that floor vent, I also use a shop vac to suck any water or dust that may have accumulated.

If it's in the bathroom, it's water from whichever appliance overflowed. I would do a very thorough inspection using flashlights and bore scope to determine how much water damage has happened.

Been there, got the T shirt.

Welcome to the forum. We also have a 2007 3000RK that we bought new and is still going strong. Since your rig was made around the same time as ours, wanted to let you know of an issue we found in ours. Your heated is located just forward of the outside door. Inside it resides forward of the steps to the bedroom and is behind the back wall of the basement.
That wall is easily removed. When we removed ours to get access to the converter (to add a smart charge plug it to give 3 stage charging).

Anyway.... when we removed the wall we noticed that whomever attached to duct work to our heater box was not having a good day. The thermal tape was not lined up well with big gaps (where output air from the heater was venting directly to the void space) and one whole duct was not attached to the output plenum on the heater but "laying" close to the outlet with about a 2" gap between the plenum and the duct. If you find your unit doesn't provide enough heat when you use the heater it might be worth popping off the back wall and take a look at the hookup.
