Hi all,

Have always done the fresh water myself, but we've always used the tank exclusively, but would also like to know any tricks to insure that the dockside water conection, and line leading to the system, doesn;t freeze up...

Is there a way to get anti freeze (RV of course) to pressurize back through the dockside water connection? Or how do I make sure this leg, is protected?

This would be for next years lay up, as our "new to us" is trucking in winterized.

Thank you!!!
 
Lou: I don't use any antifr. in my water system. I use an air compressor and blow all the lines out, and I do this through the water side dock connection. I just use a fitting there, and the admiral opens different water valves, until we get air.
We then use a few btls. of vodka in the water tank, and are ready for winter. Never have liked the pink stuff, and hard to get all out in spring.
 
I too use air to blow out my water lines, salt water wash down and my A/c Systems, ice maker.

I also install a bypass line before my hot water heater to make it easier.

Thank you Guys!

I think I may just have to do it that way next fall, I've got a little compressor that I used for winterizing the RV... I just worry if I'm getting it all that way... that's why I've always used the pink stuff.

I think it would be prudent to limit the output to about 30 psi max on the regulator though, do you agree?
 
Yes, keep the pressure down to 30-40 psi and you should be ok.

Really works and saves time, your back lugging that damn pink crap and money.

When using compressed air how does the pump connected to the water tank get purged? I think my Four Winns has a check valve to prevent the dock water connection from filling the onboard tank.
 
I just drain my tank first, before doing anything, until no water comes out...a little water in the bottom of the tank won't hurt a thing since there is room for expansion...

All the lines (don't forget the head), and water pumps/fixtures are the imporatant part...
 
Yep, drain the tank and the water heater first.

You should also crack the fittings at the water pump to let any excess water out. The air will not (should not) be able to blow out the water in the water pump.

The idea about blowing the lines out sounds good. I was concerned about the pump that pumps water from the tank. So I am thinking if I put in a little pink in the water tank and turn on the pump it will have AF in it. I am right?
 
Yes that will work Brian, or put a 5th of cheap vodka in and hit the pump. That is what we do, so I don't have that suddissing of the pink stuff some spring. We have a 150gal. tank, and it takes forever to flush that thing, so no pink for us.
