Wet and Rotten Guestroom Floor-gctid827687

[Cool_Beans]

So...it's just been one of those days

This by the way, is an implementation of the suggestions given in my thread on funky boat smells. Last weekend I pulled all the turn hoses and scrubbed and bleached the bilge areas out. Noticeable smell improvement! Today I started laying out how I wanted to rerun the piping (so far I'm thinking a combo of PVC and sani tubing). While cutting a small access panel in the guest room so I could get under the toilet shelf, noticed the carpet was wet...then I noticed the existing carpet remnant under the toilet was wet...then I followed the wet (not soaked, but moist) along the edge of the bulkhead to the closet and IT was wet...so I pulled the carpet up...it was wet along the closet...and wet along the water tank access hatch.

Around the hatch is a combination of black plywood, wet and dry...the seam over the stringer is swollen...the dark areas in the picture are a bit punky tested by stabbing with a knife. I've had happier discoveries than this, lol.

I've pulled all the valences in the head and guest room to look for leaking window bolts and I see no evidence of any water. Everything is dry and unstained. Looked around the port lights and I see no evidence of leaks. It doesn't smell like salt water or sewage so I don't think it is from the toilet. Only lead I have is I ran the tub faucet and it drips I didn't know it dripped until I checked it today. Oddly enough, it DOESN'T leak unless the faucet is on (even with city water pressure to it). Hot side drips on the AC vent hose and heads to the bilge? Cold side looks like it drips onto the floor and disappears under the fiberglass pan? Could that cause so much rot? The PO of 6 years never used the shower except for storage and subsequently everything was dry when I surveyed. The owner before that lived on the boat. I too live on the boat and have been showering aboard these last months.

So any other suggestions where I should look, what I might check, what I might be missing before I go about fixing this?

Any suggestions on how to fix this? Whats under the guest floor?

Thanks! Yall are a great help always!

Then replace the faucet. There was probably a problem started with the previous livaboard and your showering aboard revived it. If you don't have an oscillating tool, time to buy one. You can get in really close with those blades. As long as you are making a mess, take the sending unit out of the water tank and get a look inside the tank to see how bad it is corroded. Mine looked pretty bad so replacement is on the list, but after a new diesel heater and fresh water toilets.

Nice toes btw......

Beans,

You might consider removing the toilet and confirming the water supply line is not leaking. Please advise what you discover.

Worked on a 3888 that had a similar problem. Turned out to be a combination of a leak along the window frame above the closet and condensation on the inside of the window. Of course that boat is in the PNW where rain and condensation are common issues. Not sure if it applies to your climate. Tried to remedy the leak to no avail. Ended up installing a drain on the inside just down stream of the leak and piping it to the engine compartment bilge. The owner suggested that instead of chasing all the minute leaks on his 25 year old boat.

Sorry for the delayed response.

First, thank you I try to keep my toes looking mahvelous dahin'!

:woohoo:

The toilet has been removed for 2 weeks now. Though, both hoses were kinked so maybe that helped contribute? Trying to rerun the line in mostly PVC pipe plumbing.

I checked for window leaks and other above the floor leaks but found no evidence of any water intrusion. I'll pay better attention during the next rain storm.

The floor might not be as bad or bad at all as I though. Badly stained but it is drying out and solid and I took a 2" core sample and it looks good! If I can get the carpet out and dry out the floor, a good epoxy seal might be good enough to recarpet and get on with it!

A little git rot should fix the hatch opening...hopefully. Thanks all for the input!

I ran hose from about the edge of the bilge access in the galley to the toilet. Kind of like the black hoses shown in the first picture



I built a PVC manifold to join the two head drains and the line to the holding tank. I made the mistake of leaving a dip in the hose coming from the master so when the guest head flushes the first place it goes is the dip. I'm planning on installing electric fresh water flush toilets over the winter and will fix my error then.

Ironically, earlier today I removed the carpet in the mid berth floor since I am replacing all of the carpet throughout the boat. I discovered that the plywood floor was resin sealed and appears to have been factory. My 38 is a late 89 thus I wonder if Bayliner began protecting the plywood flooring at some point in the 38 run?

Definitely check the faucet in the shower. I had wet floor just to the left of the cabinet in the mid stateroom and it was water shooting out of a cracked faucet and running down and pooling in the stateroom. You can find replacement faucets at RV stores.
