Jayco Jayflight questions

[Axion42]

Hello all, I have a 2011 Jayco Jayflight 19BH travel trailer I acquired a few months back. We have used it once and everything was great! One question I have though I can't seem to find an answer to is there are 2 pex pipes hanging down on the back of the trailer under the outdoor shower. Occasionally there will be a drip coming out one of the tubes, even after all the tanks are dry (except black tank I keep a small amount of water in it with the chemicals). I have attached a picture if someone could tell me what these are I appreciate it thank you!

Could be low point drains for hot and cold lines. Look in a cabinet above the pipes and hopefully you will see a valve on each pipe. Exercise the valves, they should pull up/ push down. That may stop the drip.

Thanks for the reply. That's what I thought at first but there is no access to that side and my low point drains are located on drivers side towards front of trailer, valves are exposed underneath.

Possibly overflow / vent tubes from fresh water tank?

I'm thinking it's vent tubes at this point. Just wondering why water will randomly drip from them after parking the trailer for months of no use.

Is it possible that while you are hooked up to a city water connection, water is getting past the check valve in your pump and filling your fresh water tank without you even knowing it?

Nope my trailer is just in my driveway not hooked to anything at the moment. We took it out back in October and has been in our driveway since. All tanks dry except a few gallons of water in black tank. Just a few days ago I noticed water drip from those pipes. Strange.
