Kitchen Sink Sunk!

2007 MS TK3
Came home last night - great trip, but......
The kitchen sink (in island) has fallen in - completely detached from the bottom of the counter. Just supported by the two drain pipes. Looks like it was held in place with "glue" or caulk. I don't see any clamps or screws or ?????
How best to fix myself (if possible)?
Thanks
Mikey

Mikey: Best to get in touch with the factory and ask them what they originaly used and get ahold of some then clean underside of counter and top edge of sink thoroughly to get rid of the old stuff before re-installing with new material. You will need to keep some in reserve for running a nice clean bead around inside of the joint between the sink and the counter to leave a nice clean waterproof joint.

The problem will then be how to put upwards pressure on the underside of sink assembly to ensure stable pressure while 'whatever' cures overnight. I would start by undoing the clamp ring nuts on the drain tailpieces to allow the sink to be pushed upwards without the weight of the drain pipes hanging off it and then secure it by whatever method you care to use such as pices of 3/8" lumber cut to length and jambed under the sink to force it upwards and in good solid contact with counter underside. if done correctly that should be the last of your problems with the sink as this topic has not come up before. I suspect the way they install them at the factory is while the counter is laying on a bench upside down and they simply pile some weights on the underside of the upside down sink after coating it with caulking then touch up that joint on the inside later when the counter is installed in the trailer.

The cause of problem in your case may be something simple such as not cleaning the mating surfaces of contaminants such as oil or dust. They may even suggest you use Alcohol or something like it.

I wish my sink would do that. I would put in a stainless sink in a flash then.

I don't care much for the stainless, but it's better than what we have in ours, too. Looks good in the beginning, but sure doesn't stay white. Don't know why they are still using them in the Elites.

When you re-install the sink, make sure that the problem is not with the attached drain pipes being too short/too tight pulling the sink down and out.

We have found for cleanin the sink that the Mr. Clean Magic Eraser does a fantastic job of taking the marks off.

I installed undercounter sinks in the house, and used clear silicone sealant and supported it till dry. Did add a small wood support underside, but didn't need it. You could stand in them and they won't fall out! Can't use any clamps or brackets.

I'm betting DT used not enough sealant or installed without cleaning the surface good. Not!

Cheers,
Bill

Ours fell down also.

I cut short pieces of plywood to jam under the sink and raise it to the counter. I cleaned the old caulk. I applied new GE Silicone II caulk and pressed the supports to raise the sink. Clean the excess caulk from the edge. After 24 hours the supports were removed.

I made sure that the caulk was applied heavy enough to spread out inside under the cabinet to make a 100% seal.

I learned this in our stick house when the kitchen sink fell from under granite.

2019 Mobile Suites. Mine started dropping first trip out. Useless, DRV loves glue. Reinforced with wood underneath and good GE Caulk. They have had this issue for years and it is a well known problem. You would think it would have been fixed by now, rediculous.

Wow, 2007 to 2021 and the sinks still fall. I had an '05 and then a '15 and managed to dodge this issue.

Yep. You would think they would spend a few more bucks to brace it. Foolish.

Another one of those never had this problem
Not saying I haven't had problems. It is a RV and if you've never had any problems, that means it's parked and never used.

A known problem with DRV from day one. They just don't get it. Re caulked mine and used wood bracing. Will never fall again.
