Wet and rot .

[tapdave]

 

[tapdave]

hello again .

At the bottom right of the door underneath the floor at this corner inside is rotten .
I have sealed the roof and covered my van but the water is some how getting in to this corner .
The seal exterior down the left side of the gas holds dep’t is all I can think of for this water ingress .the seal looks good ? Is it possible the water would be getting in here lower down of the seal . It’s a nightmare ! Can’t work this out .
On the opposite side of my van it is the very same ,,,bottom corner !

Help please if possible ? Any advice will be welcome .

 

[tapdave]

Should have said bottom left of the gas dept door underneath ..sorry !

 

[BusyBuilder]

What is it like inside, have you checked ceiling/wall and inside gas locker ?

 

[dunnah01]

Spray from the front wheel can get to that area

We fitted mud flaps to our motorhome to prevent such spray. We hadn’t any problems but acted through suspicion that the spray may become a problem.

 

[The Wino]

I'd look underneath at whether there's mud holding moisture against the floor and whether the floor to side panel seals are still intact

 

[Speve]

A photo of inside gas locker might be useful as it should be sealed from the the rest of the vehicle if it is then could it be water spray as suggested hitting outside of gas locker and deflecting onto floor?

 

[PaulW2]

Do you have a double floor? Sometimes one can have an internal water leak from the van's pipework which then flows to the lowest exit point. If the van is left stationary for a while water can pool and cause damage.

 

[tapdave]

I will get some photos .
I have not used the van for a few weeks but I do cover it when rain here is imminent as I’m aware of this leak . Phots to follow!

Here are the photos .
Gas locker is very dry but to the left side it’s wet .
Sorry for being vague ..

 

[tapdave]

This is the corner it’s wet ,the floor is bad in the corner and the damp is creeping up the inside

 

[PaulW2]

Wet at the very lowest point where you have that gulley, but not above it? If that bottom bit you can see is part of a floor or level section I would think the water may potentially be flowing from elsewhere, with either an internal leak from the water system or an external leak as the source.

 

[Diabalo]

It could be coming in from anywhere, water can wick a long way so you need to expand your search.

 

[tapdave]

Thanks Paul
Yes the darker photo is the floor bottom where I have lifted a portion of linoleum ..
I will take a look but on this side corner there is no plumbing .

Must be external leak but this is beating me as the exterior seal that side looks intact and also the cover is on that points to your theory that it’s from low level ..
God it beats me .
Thank you all for your input and dunnah1 for the help regarding my seperator yesterday .

Inside gas locker seems to be very dry . The opposite side of van in the photo is exactly the Same..just the corner floor very damp and corrosion set in
I am not seeing or feeling any wet soft spots on the ceiling and walls seems dry and intact .
No rusty colour blemishes to see .

 

[Orion]

If the gas locker is sealed as it should be then could a leak from the window surround above be coming down internally and tracking across to the damp area?

I am going to take a a better look at your idea when the rain goes of . The window has just been sealed but I could have quite easily missed something .

Good point again and thanks

Is the wet bit the extreme end of a floor that runs much of the length of the van? And is there, anywhere along the length of this floor, plumbing - pipes, taps, boiler, water pump, tanks - above the level of the floor?

If so, the water can run quite far from its source - I've seen it travel about 4 or 5 metres from the source, in a double floor, before emerging somewhere.

It's probably just worth eliminating that as a possible source if there is any possibility that it could come from inside.

 

[Diabalo]

If that's the fresh water filler point to the right of the gas locker, It may be worth checking the filler pipe to the tank to see if there is an issue there.

As water can travel some distance before settling and causing rot, I would consider a damp check to explore where else damp may have travelled from. The damage would tend to be caused, I guess, when the water cannot escape and spends time there.

Mudflaps will only stop some of the water but the pesky stuff can be quite determined

I will get underneath the MH tomorrow and check if water is tracking along the length of the van .the wet points are at the corners ( both sides opposite)just before the drivers cockpit and passenger .. I have not had the vehicle out for ages to use so have not run heaters plumbing etc” .. it’s defo only when it rains outside . Cheers very much .

Tell me about it ? Stress on !!

When I bought the van it had been garaged for two years and never used over this period .
This rot in the corners I have found were only exposed once the vehicle was out in the rain .
Defo, it was old damp that had been dried being undercover for so long .
Damp check to check out the rest may be a prudent move
Thank you

Yep the water filler pipe I have seen to and made sure it’s tight and safe for filling .
To be honest the pipe was leaking but some weeks ago I repaired this .
Thank you

Cheers Orion.
I have sealed the windows so guess I have eradicated this as a culprit but hey ho I will double check as I’m greener than green with this camper van stuff . .

Cheers for the advice

Agreed.

Even Canute couldn’t stop all the water……..




…..although Moses did quite well!
