Leak in the front storage compartment
Believe it or not we had 3 or 4 days of rain in So Calif. and I had a puddle of water in the front storage area in a 2019 Montana 3120RL 5th wheel on the passenger side. I looked all over tried are the faucets sinks drains and the water pump never loses pressure, all I can figure is it leaked around the compartment door but the seal looks good.

Get inside and have someone run the hose on the wall above the door. YOu will probably see water running in somewhere.

Ditto with Tom that's the best way to find leaks!

Mine would leak and have puddles in the front and rear corners of the basement doors. I finally determined that the black aluminum extrusion around the door itself isn't sealed. Heavy rains the water would fill the door until the water finally ran out the latch hole on the inside. I sealed the door AND latches on the outside and ..... No more leaks!! Also tighten the latch pressure.

I will inspect everything around the door, the seal itself looks good and the door is hard to latch so it is tight I will check the frame and reseal it. The other door is ok it's just the passenger side

I Had to remove & reseal all frames, they only had a bead of silicone on the exterior. When the door would close the frame would move a little. removed, cleaned, added butyl tape, reinstalled & added additional screws with shims. Couple days I cleaned the excess butyl & siliconed. The doors are now rigid & dry, a couple that didnt show water were wet all around the frame so good idea to check them all.

Storage leak
I need assistance/advise on my water leak issue in the passenger side compartment, My rig is 2017 Montana 3921 FB
I was flushing my black tank and suddenly I notice there is water running down from the passenger side landing gear and the inside of the cargo, I look above inside the cargo and I saw 4 water lines 2 white and 1 blue and 1 red I noticed water gushing from the white hose I knew I don’t have water running inside so I shut the the water from flushing and it stopped leaking and just to confirm I tried again and it’s positive it leaks when I turn the water to flush. I tried to see if I can access the area but there is no place I could do that. I don’t know where else the water went I’m glad I’m in El Paso tx warm and dry hoping that I did not ruin anything on the inside
Any assistance is greatly appreciated
Thanks in advance .

The two white are for the black tank flush and go up under the bathroom sink if you look under the sink for the white lines you will see a black valve. that is an anti-back flow valve and it has probable failed you can take it out and get rid of it like most of us have or you can get a new one the OEM valve in a piece of junk.

Montana has placed that valve in some very hard to access locations. Early years had it behind the shower wall and you had to cut a hole from the other side through a cabinet. As it is clear the valve is the problem, I would not waste my time. Cut the white lines where you have access and join them together with a couple of Shark Bite fittings. Problem solved.

Carl is right if you can't get to just cut the white lines wear you can get to then and join them their. I could get to nine but I did cut them under the floor of the bath.

You want to be able to "loop" the 2 lines together, thus eliminating the "vacuum breaker" (back flow device) that is leaking. Very simple fix that will last the life of the coach.

Posting pictures is relatively easy. There are a couple of sets of instructions which might help. Go to http://www.montanaowners.com/forums/...ad.php?t=70323 and read posts #8 and #25.
If you need further help, let me know.

I used two elbows with a short piece of Pex (from where I cut the lines) to bridge them together

My 2016 did the same. It was my door which had to be replaced. I finally crawled into the compartment and saw the daylight coming through the seal.

I’ve noticed on my 2010 3400RL Montana that if I don’t lock the door, and just use the right twist closer that it will leak a little if the rain and wind are just right. Locking the left side eliminates the leak.

Sometimes it's not the door that leaks, but the weather stripping on the door gets caught and rolled off. Had this happen on my two large basement doors already and one rear one. I simply went to Home Depot or Lowe's and got some weather stripping as below but didn't put it back on the flange facing outwards as before. Instead I put it on the frame flange facing downward so the door compresses the foam and then go out to the edge of the door where it stats to turn down and stop it there. I cut out the seal that was coming down in the places where it had came loose. I had to go back and trim off about 3 inches of the last pic as the door tried to peel it off, so I stopped it just past the hinge.
