Kitchen sink drains!

[AWF1945]

Correct me if I'm wrong please. Isn't plumber's puddy supposed to be used on sink drains? Mine has leaked under the cabinet making a mess. Luckily i had a plastic tote under there that caught the water.

I pulled apart and its sealed with silicone. .. lots of it.. and it's hard to remove. The plastic drain insert swims in that hole. Its not snug. Was that installed like that at the plant. ? Its a terrible fit really.. picture to follow.

Should have took a picture before I started removing silicone. .

The problem with the putty, is the plastic drains are fairly cheap and to get enough pressure on them to squeeze the putty, they would probably strip threads or break. Using silicone is acceptable and probably warranted in this situation because of the flexing of a trailer. I would pull it and reseal with a nice bead of silicone.

Not trying to argue but fresh plumbers putty at room temp is VERY soft.
It would/should work fine to seal that drain- plastic fittings and all.
Silicone sealer should work fine as well but it's much harder to remove if
you ever need too.

It should have had a ring of plumbers putty to seal between the drain flange and the sink and also a rubber ring below the sink.

I seriously doubt that many, if any, installers go the trouble of doing it right in these units.

Thanks for the replies. No putty at all. Globs of silicon. Ridiculous, yes it had rubber seal underneath. I'll start with putty and go from there. Geez..

Ummm, what!

Plumbers putty...always. Never silicone. Especially sealing plumbing fixturers.
Don't allow any silicone near my Lexi. In fact, it has a silicone early warning system. Anytime a tube of silicone comes anywhere within 25 feet of my Lexi, the horn goes off and the lights blink.

Okay problem solved. Replaced plastic sink drain with a real one ;-) plumber's putty Teflon thread sealer on metal to plastic trap pipe ... there ya have it. I'll do the other sink when my fingernails grow back from removing that silicone. Silicone has its place. ... but not for this. If your reading this and your the one that did this to my Dynamax. . Your a Dummy! :-) lol The new drain matches the faucet hardware better.. and before anyone askes, no.. the sink is not plastic. Thanks for the replies... no damage done.

I will print this off for the line and see what we're doing today. I'll also take a look at the drains. Those solid surface sinks aren't cheap, but I have always preferred stainless steel. Those things are bullet proof and no reason to be using plastic on either.

I like this...a silicone early warning system. I like to use plumbers putty. I am sure the MFR has its reasons for silicone. I'm not sure of the chemical pros/cons here with the exception associated with the replacement process. What a PITA to remove silicone...ouch. Let us know how it goes Slim...

I replaced the plastic with SS and putty in the kitchen sink, no leaks as of last fall.

Looks great!!
We have upgraded most of the plumbing fixtures in our trailers over time.
Plastic faucets and cheap shower wands-- ugh!! All gone now.
You did good!
At least our new rig came with a porcelain potty!

Lol.. was that system an option

[grumpy0374]

I replaced the kitchen and bathroom plastic fixtures with some quality home style fixtures I found on Amazon, along with replacing the fittings to the faucets with some stainless braided water lines with cut off valves.
The funny thing is the quality fixtures only cost a few bucks more than the POS plastic fittings.
As for silicon...I can't see any use for it on an rv. Just no place for it as there are too many quality caulks and sealants out there that are the proper ones to use. Only reason I can see for it's use is that it's cheap, and used as a cost cutting measure.

Most if not all shower stalls are sealed with silicone, thats a PITA too when you get a leak. Its just a pain to remove. Share what your using in place of it. Thanks. .

[grumpy0374]

Latex bathroom/kitchen caulk. Much better than silicon. If thats what they use to seal the shower stall, than I'm lucky, cause the brain surgeon who installed the stall on our Lexi forgot that step. There was no sealant used, and when I saw what was missing did it myself using latex sealant. Sealed shower door to wall, and shower pan lip, and ran a bead around lower area seam where shower walls overlap the shower pan. Also ran bead around kitchen and bathroom counter tops where they meet the walls.
Two years now and no problems, no leaks.
It's available in white beige/cream color, and brown. Lowe's, Home Depot carry it in a large toothpaste type tube.
Look for Dap Kwik Seal Plus, or anything similar. If it states somewhere on the packaging that it's paintable, then that means there is no silicon in it.

Thanks, I have some of that called Dynaflex by DAP. Guess I'll dig it out and redo shower.. I'll use Dynaflex on my Dynamax lol :-)

[AWF1945]

Tell ya something even better than Dynaflex. Its a product made by loctite. Tub and Tile no silicone, it goes on whitish dries clear. I used it before too. I did find an old tube in my box. Need to get a new one.
