We have a 2022 337 RLS Reflection and I have a leak on one of my grey tanks and I need suggestions. We discovered the underbelly sagging and it tore loose on the door side between the door and the basement door and it was full of water. Looking in with a light I could see no source of a leak and we were able to get most of the water out and I estimated that we had about five gallons of water. I emptied all the tanks and we ran water in all sinks and the shower and observed no leaks. Since we were leaving Colorado for Montana the next morning, we sealed up the underbelly and decided that we would watch the two holes I drilled in the underbelly to get the rest of the water out. From Colorado to Montana we saw no leaks out of the bottom holes and we dumped our tanks every night.
In Montana the first night we saw a drip from the holes and the next day I pulled the entire underbelly off from the front to the doors and right away (THANKFULLY) I was able to see where the leak was coming from and (THANKFULLY) it was from a grey tank and not the black. In the picture I posted you can see that the leak is right at the bottom of the connection. The grey tank is the kitchen grey tank.
The camp host is amazing and he has a lot of experience and he helped and offered his opinion and his first thought was to tighten the hose clamp. The hose clamp was very loose and since I have tightened it has not leaked. What’s interesting is that the sealant in and around the connection is very sloppy and nice and clean on the connections to the other two tanks. While the leak has stopped for now I am not trusting it to stay this way one when we hit the road again.
I have a new hose clamp on the connection because the other one had the head rounded of (???) and as the camp host has suggested I am thinking of cleaning off the outside of the connection and re sealing it. But, one person suggested not to be to aggressive with cleaning it and to leave well enough alone.
Questions
What type of pipe is this? I assumed it was PVC but one of the people who looked at it said that the RV companies use another product.
Depending on what type of pipe it is what should I seal it with?
If it starts to leak again what would you recommend doing.
I have considered having a local plumber come by and offer suggestions.
