Hey gang, I have to be honest here. We were so enamored with this Host camper and the fact that it was only 3 years old I didn't look as closely as I should have. After our first trip I noticed some dripping at the rear of the camper. I thought it was coming from the sewer hose. After I unloaded the basement I saw some staining I hadn't noticed before. I crawled under the camper and started looking at everything. Something had been leaking for a while and there is some minor rotting. I crawled into the basement and took out a (bulkhead?) exposing the grey water tank. The pipe coming from the kitchen sink and dropping down into he tank has no tail piece. It butts up to the tank and was sealed around the outside. I twisted the pipe and found the seal broken and water has been leaking out for some time and has been wicking all over and causing lamination problems. What product would y'all recommend to seal this? I'm thinking it will need to be a silicone type and put on a heavy bead. I have a 20 second video but not sure if I can post it. Anyhoo..... thanks in advance.

I would suggest you go to a marine store. They would know what to use as many boats have watertanks. I am thinking Sikaflex 291, but there is many different brands. Check it out on the internet.

If it just has a flange butting up against the tank, I would not use any sealant to try to fix it. The ones I have seen are friction welded in place, it sounds as though the weld has broken or was improperly done to begin with. If it is just a pipe stuck through a hole in the tank with sealant around it - that is simply poor construction. A pipe connecting to a tank wall is going to have some motion and stress on it, there is really no sealant that will last very long in that application - especially on polyethylene which is a hard-to-bond material. There are some fittings made for this propose which have gaskets and nuts clamping to the tank wall, but they generally require access to the inside of the tank to install. Call Host.

Without a picture we're just speculating at the issue. If you do need to install a new connection, there are some here that have added a portal access to the top of the tank that would let you reach in to install a new fitting. They aren't too expensive. If you get your issue defined as need to install a new connection, I'll see if I can find the info.

With the camper only being 3 years old I would call up Host and see what they can do for you, they might tell you to take it to the closest dealer and have it fixed for you.

when you reassemble, I would recommend using fernco couplings to give the line some flexibility and reduce possible stress on the actual tank connection
