Fresh water drain tube falls out

[lesteph1520]

We have a 2016 Cedar Creek Silverback 33IK. The blue tube that has the fresh water drain valve on it keeps falling out. We paid to have it repaired, supposedly they replaced where it screws in on the tank, but it still keeps falling out. Anyone else have this problem and any suggestions on how to solve it?

Can you post a picture of where it's disconnecting at?
Is it a welded connection or a compression or threaded connection?

I can't get a picture right now, but it is a threaded connection. We tried putting plumbers tape on it. It tightens and will hold for awhile, (even through very rough roads) but after we drain the water, when we very gently turn the valve, the whole thing falls out.

Take it out and clean it well and use a dab of silicone caulking on the threads. That shouls stop it from backing out.

P.S. This is the only place on an RV I recommend using silicone caulking.

Thank you for your suggestion. We are going to try to get our service people to fix it...again, since two tries haven't worked. But we will keep this idea in our mind.
