Shower not draining all of a sudden
Hello folks,
My 2018 3739 FL has been good so far - until last night. Took a shower before bed and all of a sudden the shower drain stopped up. This is a new unit only less than a month old. I did notice the expanding foam insulation around the shower downspout that connects to the main drain has shifted down - appears to have pulled away from where it had been applied on the underbelly. Vent may be clogged or may just need a good plunging and some Draino? Seems strange to all of a sudden have this issue after using the shower daily - ideas?

Just asking but is the gray tank full? I'm sure you already checked that. the next thing to
do is snake the drain you may have a plugged trap don't see to many plugged vents the vent use ale only causes slow draining does the sink fill up to?

Be VERY careful with a snake, you may have the hepa thing in place of the standard p-trap, you could destroy that hepa thing.

You have a HepVo valve instead of a P trap. A search on HepVo will provide lots of info. Here is one that jumped out at me

If that's a part of the new fangled hapa trap, I want no parts of it. I would be replacing it the tried and true p/trap.

Man, I don’t know. It doesn’t resemble any part of what little I saw of one in a video. Hopefully someone can tell me WTH this is ! I don’t know what else it could be though.
Thanks

The Hepa valve is a one valve you put in instead of a pee trap not stock on most rigs.

HepVo valves are definitely stock on Montanas and have been for years, Perhaps not on HCs (I haven't looked at those).

Thanks everyone - the other sinks all fill and drain fine. The grey tank is wide open. The black tank is closed. Plunger may have helped a little - whatever it is it clogged the drain pretty good. I dont think Copenhagen would do that. Letting a little Drano work on it for a few min. We’ll see. I can see a P trap from the belly so if a Hepa thing is supposed to replace that, then I dont think I have one of those.

Well Copenhagen is not really chewing tobacco. I am not a big fan of Drano either but desperate times can call for desperate measures.
Thanks,
Max

I just looked up the floor plan for a 3730fl. The bath is towards the rear. Is there a dump valve that you are missing ? (not pulling) towards the rear around the wheels somewhere. I am guessing the tank is full.

Yes sir there is. I have one up towards the nose, and one behind the wheels in a box along with the black tank valve. Both grey valves are pulled open. I agree at this point, there must be a broken valve and the gate is not opening so the tank must be full. One valve (the rear one) feels like it is actuating (has a little drag on it). The one up front feels like it may not be opening a valve. Good thing is, Keystone has authorized a mobile tech to come and diagnose and repair. Maybe have it fixed tomorrow.

It does look like that is the case. If the water rises in the shower as you put water down the sink drain that means water is backing up INTO the shower without you adding water to the shower. Again, look for an additional grey water dump valve on or near the frame in back of the rear wheel on either side.
Keep us advised with your fix. We'll help you through this.

Shower stopped draining - Part 2

Well, I have been wrong before (once). I can see the membrane just below the shower strainer so I have a Hepa. Plunging did not help after all. Neither did Drano. I began bailing out the water with a Dixie cup but didn’t seem to be getting anywhere so I went to a trash can to bail with. Sure enough, water is coming in from the drain. Both grey tanks are open - nothing comes out the sewer line but flows back into shower. Now I wonder if the tank valves are operating - they were a two weeks ago! It is like the grey tanks are chocked full but wont empty. Ideas?

Then x2 on Carl's advice, unless there's an unopened valve....
Or, you can take it back and have it addressed under warranty.
