Water leak blue/red line bathroom

[MKM]

Hello! We are struggling here. We have a water leak in the blue and red lines under bathroom sink. I can feel dampness but the inside of the cabinet is not wet. However it’s wet on the floor between the sink and shower and those lines are wet. (Water traveling down line?) The water has leaked into living room under fireplace. We are trying to figure out if the whole line needs to go or even how to reach under the sink! Any thoughts or experiences?

I would think you would have to lay on your back and get in as far as you can and reach up to see if the connection to the faucet is where the leak is. It could have loosened up.

We tightened it still leaking took off each line and Pipe thread sealant and are tightening it back up to see if that works!

Be sure there is no cross threading. Can you see where the water is coming from?

We think it’s coming from where the water line connects to the faucet. Super tight fit so can’t see going by feeling only. It seemed to screw on correctly. Hopefully that’s it. Water is no good in these trailers! Giving the sealant some curing time although not sure that’s necessary..

There are rubber washers and sealant only reduces the ability to tighten the connector down.

Like was already stated cross threading is the biggest problem!!!

The sealant didn’t work still leaking less but still. Cross we don’t think it’s cross threaded any other suggestions?

I always install shut-off valves and flexible connector hoses. I hear some don't like that method. But I have one hell of a time getting that rigid PEX lined up square, so I get cross threading if I don't.

Shark bite has the valves if you don't have the tools.

The best method described by Kevin. The pex is to rigid and puts pressure on the cheap connectors. Take the strain off with flexible faucet lines, 1/2 inch female pipe thread on both ends, and put a shut off in while doing it.
