Smile Water leak under bathroom sink

We live in a brand new 2018 Jayco Northpoint. We have double sinks in our bathroom and the one on the left seems to have a leak as there is water in the compartment below the sink. I have looked for the leak a few times but can not seem to find where it it coming from. Nothing in the piping feels wet and everything looks tight. it's not condensation as it a lot of water fter a few days. Has anyone experienced anything like this? Appreciate any help...Thanks

Check all the fittings and check the faucets as well. They’re not always as tight as they should be (or have loosened). Also, run the water to see if you can see any leaks (suggest fill up sink then pull the stopper)

I use toilet paper. Start wrapping and laying it out. Sooner or later it will show itself.

Could it be the "P" trap fittings?

I had this problem. They installed the lock nut but not the seal. Give a light tug on the "P" trap and see if it is loose.

We have a 2018 NP 377. Just had to hand tighten the fittings under the sink. No leak since

Sometimes the black tank flush "vacuum breaker valve" is located under sinks and are prone to leak when in use.

The valve looks similar to this:

Ditto! Mine was under the kitchen sink. I laid out paper towels and the wet spots helped me track down the culprit.

I had a drawer fill with water found the water supply loose and the water ran down the pipe to the low spot. TP idea is great.

Same thing here, tightening up the hoses didn't do anything (and they weren't loose). Splashing water around the sink area led me to believe it might have been seeping between the faucet base and countertop.

Puttering around the camper the other day while it is in storage, I removed the 12mm nuts and pulled up the faucet, and sure enough, there is no gasket and was no sealant at that junction. I applied silicone sealant around the base.

Haven't checked to see if that solved it yet, needed to let the sealant dry.

I forgot to mention that I also caulked around the perimeter of the sink(s). It wouldn't be the first particle board countertop that rotted out.

Yeah, I filled up the sink, pull the stopper and didn't see anything leaking. I'm thinking it's a S-L-O-W leak. I have put a towel under the pipes in the cabinet and it takes about 3-4 days until it becomes totally soaked. I've looked at the fittings and everything seems tight. haven't actually taken a screw driver anything yet...I'll try that

Thanks everyone for the great ideas..I will most definitely try tightening everything and using TP to try and pin point it.

In our NP the pex was plumbed straight into the faucet. At an angle! Sigh...
There was no water under the sink. The line/lines were leaking slowly and running down the pipes to the 90 in the basement.

I bought 2 flexible faucet supply lines and two sharkbite shutoff valves that fit. Solved the issue for me.

I replaced the faucet with a taller model while doing all this.

So perhaps check the pipes for slow dripping water as well!

Hope you find your leak and it is an easy fix.

In my Pinnacle I have replaced all 3 drain assemblies. Double sink in master and the half bath. All 3 had defective drain assemblies that cracked just below the sink. Purchased new ones at Lowes for $12 apiece, problem solved.

We have a 2018 Jayco 38FDDS and had a "mystery leak " under the bathroom sink. Turned out to be a the hot water hose connection to the faucet was just not quite sealed. Did not leak all the time, After we turned on the hot water heater it would " leak" then stop. Then we shut down for the week. when we turned on again it leaked... I found it by putting down paper towels , and lightly wrapping paper towels on the fee lines. The fix was to " tighten down the fitting" no more leaks….

We had a leak that would show up on the floor coming from under the sink cabinet. It was the simplest thing but took us forever to figure it out. The drain fittings were not tight and the plumbers putty under the sink basket was hard so we were getting leaks from both places. The basket strainers were the first thing we fixed and then when we still had a leak we checked the drain fittings on the p trap, it has been 2 weeks and no more leaks.
