Noticed a small amount of liquid dripping in the basement area which is under the sink. Traced it up and there seems to be a slow leak in the connection between the supply line & the faucet.  There are 2 white plastic supply lines & we have tightened them but no change. Can anyone tell us how to fix this?!

I'm guessing folks don't have advice on fixing this.. and would imagine that rigs vary enough that it's difficult to give advice like this online without much info to go on. 

Just a few quick questions.

Hi Steve

I know the feeling when it comes to plumbing. I've found plumbers putty to sometimes help with leaks like that. It does require some taking apart and putting back together though.

Have you shut off the water and removed the connection? It may be that the gasket/seal in there is damaged or otherwise messed up. If it is a PEX connection, they use rubber "cones" for the seal. Or, it could be a flat washer-looking seal.

Sometimes tightening can make it worse. If it is coming from the supply line for sure, I would maybe try this first - turn off the supply and dry everything off. Have one of you under the sink, and the other turn on the water pump. See if you get the leak with the water pump pressure. If so, try to find where the leak is originating using a flashlight. You may be able to use a dry paper towel to see if you can isolate where the drip is coming from.

If it is still leaking, you can also take a picture of where you suspect the leak to be and post it up here. It might make it easier to see what the connections look like.

If it is coming from the line itself, which is unlikely, you will be able to cut out the leaky part and put in a coupling. All of that should be easy enough to find at a Home Depot or compatible store.

Our kitchen is on a slide, and I find that my drain lines get a little loose sometimes. You may want to feel those as well in case the drip is coming from there. They are usually hand-tightened fittings on the black drain pipes under the sink.

Good luck - post up some pics if it is still leaking!

Thanks, Kev - we think it's the gasket and haven't had any more leaking this week, cross your fingers!

We've had several small leaks at the gaskets/connections. All the rattling round in the RV just sets them off. Alot of the time it's just a poor connection. Plumbing tape has solved all our problems so far. We undo the connection, wrap plumbing tape and re-do the connection. Viola...no more leaks.

 

It's a similar idea to the vaseline you used...just a different way to seal the connection.

Hey thanks, Nina!!

Just because I am a geek, I will add this: I typically stay away from using Vaseline (petroleum jelly) on any rubber. Petroleum jelly will deteriorate natural rubber, but I believe it is OK on compounds such as neoprene. However, I can't ever tell the difference between the different rubber compounds in gaskets and o-rings, so I don't use it at all.

For lube on gaskets and o-rings, I use silicone lubricants. It is safe for all of the rubber compounds, and is safe for water supplies. I buy mine from scuba supply stores, but it can be found anywhere.

Just being a geek :)

thanks...love the geek in you!
