 If faucet has a hard rubber or plastic baseplate do you need to seal it ??
Author: cvcman (NY)

Our new faucet came with a hard rubber base plate gasket, should I still have sealed it to the sink top with silicone or something ?? I has a lip all the way around it that the faucet sits into. It didnt say anything about sealing but someone told me to plumbers putty under it which makes no snse because it would squeeze it out when tightened because the gasket is all the way under the faucet.
If I siliconed it I would think it would be a pain in the a$$ to ever remove....What do you guys do..
Thanks

Mr OCD

if it has a rubber gasket there's no reason to caulk it

if it just has a hard plastic piece that goes under the faucet i typically use plumbers putty or caulk depending on what the surface is...i dont use silicone- i use adheisive caulk

Depends upon the surface the faucet is being mounted to. Granite or marble gets silicon, putty for everything else.

its cultured marble ( whatever that is ) right now i just have the base gasket down and it seems ok I dont see any water leaking into the cabinet....It seems like the putty would squeeze right out because the top of the sink where the faucet mounts is nice and flat and smooth

Take a cup of water and pour around the base of the faucet and see if any water drips into the cabinet. I think Oatey makes a plumbers putty thats safe for cultured marble.

It NEVER all squeezes out, but the oil in regular plumber's putty will stain the marble.

If the faucet sits nice and flat on the gasket and surface, and stays that way after I snug it down, no caulk. I never use plumber's putty on faucets. If there is any disortion or gaps I'll use a waterproof caulk/sealer. I think GE makes a silicone sealer that cleans up with water.. I haven't tried it yet.

I see the plastic and the directions.They either make it plain to see or they buy the cabinet base.I save the directions to the customer purchased facets.Never use any thing not specified by directions.Hope they bought moen.self sealing base.???unless you screwed up and used putty under it!!!!I cannot fix the failure before it occurs.be sure you note your thoughts of failure as billed.Will I bend a s/s sink?yes .will I add putty or silicone chalking as needed yes.Will you note the reason you did?

I have seen most faucets, that did not use either putty or another caulk, leak at the base down into the cabinet below. Always use putty or another kid of caulk.

where does the water come from ?? If the faucet itself isnt leaking it would have to come from water splashed up on the faucet, alot of water...

That is exactly where it comes from, splashed water while using the faucet and sink.

Mine leaked. I thought I needed new supply lines so I installed them. Still leaked. Then I discovered the water that puddled next to the faucet base somehow got past the putty and down it went. There's no substitute for a good seal wherever there is water. Water finds a way.

FYI: Plumbers Putty for *EVERYTHING!!!!

*Except where incompatible with certain materials (pourus materials like wood, apparently also some Marbles), in which case a form of caulking sealant.

unless directions explicitly state not to use ANY sealant (possibly in the case of a rubber gasket??)
U NEED TO USE SEALANT BETWEEN CONNECTING PIECES OR WATER WILL LEAK THROUGH PERIOD.

Sorry for the caps, but it seemed necessary.

To anyone thinking water will not leak through.... c'mon, where have you been living, the Moon?....

FYI, its not only the to prevent the cabinet from taking in water, but to prevent moisture for gathering and collecting under faucet but above sink surface. prime place for mold, etc.

Apply the putty (as snakes rolled up) as directed in a video, use google to search for "how to apply Plumbers putty to [YOUR APPLICATION HERE]".
The excess squishes out while your slowly tightening it down, and is easily cleaned up, very similar to collecting
play-doh.

Good luck all!
