Winterizing question

I am winrerizing my 2015 36.1 Palazzo for the first time and things are seeming a little unusual. When I opened the valve to drain the fresh water tank, only a trickle came out. Took overnight to drain half of the tank and it stopped draining with 2 of water left on tank. Something wrong?

Thanks,
Ford

You have overflow opening somewhere in the system that should have allowed water to drain with strong flow. If that is plugged up, I can see the tank draining slowly. As for 2" left, not a problem. You've drained it past the level of the drain hose fitting. Even if what remains tries to freeze, you have ample expansion space.

Thanks for the reply. I located the drain valve and that is what has the slow flow. Guess it is blocked. Will try to clear it next time. I figured 2” was not a problem, but with slow flow, wanted to ask. My prior coaches drained lower. Raised the right side of coach with jacks and flow started again, so I figured that remaining water was by design.

Open the drain valves under the wet bay Then open the outside shower faucets.
That will fix your problem. I opened the kitchen faucet and that worked for me tank drained out fast.

yes, anytime you want to 'drain' something, open another 'end'(faucet, etc), that will allow the necessary air intake to provide the gravity flow effectively. If your toilet at home didn't have a plumbing vent(air), it would have the same problem!

also, a note: a large tank of water would take a very DEEP freeze for a very LONG time to create any type of 'freeze' issue with water in your tank - emptying it does little toward 'winterizing', which is mostly for your small amount of water in your water lines. Freezing water 'expands' and can create issues with water connections.
A 'full' water tank would take more to freeze than a 'almost empty' one.

I had several of the faucets open when draining the tank and the flow was still very slow. That is not the problem.

Keeping it simple. If you are 100% confident you have good venting to allow water to flow out freely, then the problem must be at the drain point/valve..
