Antifreeze inlet

[metalmike57]

Ok so I'm a new owner of a shamrock 233s and winter is right around the corner...so I like to be prepared....I'm trying to figure out this system for winterization.

On the front right side of the tt there is a antifreeze inlet right next to the city water inlet...do I just have to connect a hose to it and run the water pump to suck up the antifreeze from the gallon jugs?...could it be that easy?

[metalmike57]

One more thing....on the opposite side(left of the door) there is a tank flush inlet?...how Does that work?...both gray and black water or is it for the clean water holding tank?

BE SURE you have bypassed the water heater BEFORE you start.

The lite came with the hose/tube for this, it was in a drawer.



The way I do it.



Just turn the water pump on and then open one faucet at a time, I like to start near the water pump and work away from it.

Takes me about 30 minuets including pouring some in the toilet bowl and an extra jigger in each drain.

Be sure to do the outside shower if you have one as well as the low point drains.

The tank flush is to flush out your black tank after emptying it. There are nozzles that spray around in the black tank. Do not use your drinking water hose for this for sanitary reasons. And DO NOT walk away with it spraying in the tank with the black valve closed. You will find numerous stories on the forums about water (and whatever else) coming out the vent on the roof if you forget to shut it off.
I don't know what a fullway termination valve is. Maybe the black tank valve?

Seems to me that a valve has to be selected to switch the pump over to that port. I don't think it can be active all the time and still get water from the holding tank. The cleanout is for the black tank. Just follow the "CAUTION" label.

Don't forget the checkvalve in the city water fitting

Likely for the black tank only.

Drain Black tank first close the valve.

Drain Gray tank then close the valve.

After hooking a one purpose hose to the trailer and spigot turn on the water.

IT is VERY important that you do NOT walk away or become distracted at this point.

Let the water run for about 10-20 gallons of water(depends on tank size) then open valve.

Repeat till water runs out clear.

I had a pop up before this and I am familiar with the winterization process....just a little confused about the antifreeze inlet...is it that the water pump works with this and not the city water inlet?...would there be any water in the city water inlet that could freeze?...do I connect the hose to the city water and fill with antifreeze?does the water pump work with that?...probably not...

[metalmike57]

And the black water flush inlet on the other side do I pump in antifreeze into that , when I'm done?
....if so how?...hand pump?...I have one for my pop up

With antifreeze in the system and pressurized pull out the screen on the city water inlet and there is a checkvalve to keep pump pressure from pushing out water. Press in hard in the little nipple, and stand out of the way. This will push the antifreeze out of the city water connection.

[metalmike57]

I thought that check valve was on the fresh water cap or connection?...it's dark here now (ny) I'll check it out tomorrow...thanks

[metalmike57]

Oh...with the antifreeze being pumped in push in that check valve on the city water inlet and antifreeze will shoot out...is that what you are saying?

[Toddupton]

Not the tank fill but the city water connection

[bubbles]

I could finally make out what the antifreeze sticker says about the valves for winterizing. Just need to find those valves. Both of the ports in question have instructions for what to do. Just follow them.

[metalmike57]

Ok thanks everyone....getting late here gonna check it out this weekend ....still got a couple of trips planned before I winterize it...

No. All you have to do is flush the toilet to get a little AF into the tank (after you've flushed and drained it as much as you can).

Yes you do pump antifreeze in the black water flush. A lot of water I'd left in that line depending on how the back flow preventer is installed. Or you could blow air in it also.
