Question Kitchen sink gasket.

The kitchen sink on our 2012 32BHDS looks like it was sealed with a silicone sealer and when we run the hot water in the sink it gets very flexible and can be pulled off. I'm concerned that it will allow water to run down the outside of the drain and into the cabinet below. Does anyone know if this is normal and the silicone is just the excess or are we looking at a problem that needs dealer attention. Pictures will follow as soon as I can get them.

Is the silicone grey looking and very sticky? It may actually be butyl. In our trailer, I believe that the sink spud was sealed with butyl. The butyl oozed a lot. It was a mess, and looked nasty. I cleaned it up several times by scraping away the excess and removed the remaining residue with a rag dampened with paint thinner, but it kept on oozing. I removed the spud and re-sealed it with plumber's putty. The putty oozes once, you scrape away the excess, and then it quits oozing. But, I'm not sure how long the plumber's putty will last in an RV application with the associated movement and vibration. I did the re-sealing over a year ago, though, and no leaks so far - and we've used our trailer about 10000 miles in that year.

By the way, probably silicone used as a seal for the spud would not a good idea, as once sealed it is probably sealed forever and the spud could not be replaced if needed.

Since (I guess) your trailer is still under warranty, you might want to complain to your dealer and let him figure out how to fix it. If the sealant is butyl, it probably is sealed up well but it sure makes a mess in the bottom of the sink.

There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.

That seems to be it. Hot water seems to make it appear more. I'll contact the dealer and let you know what he says.

Place the gasket onto the tailpiece of the sink strainer. Screw the nut on the gasket to the tailpiece.
