Winterizing question and unknown hose hookup

I managed to raise the mattress and keep it supported today while I removed the plywood over the pump on the Escape 19'. My intention was to install a winterizing hose but upon inspection of the tight fitting pump area, wires and tubing of unknown diameter I decided to use Tammy's method #2 and merely drain the system without adding antifreeze. This will allow some limited winter use. I also planned on installing an accumulator tank on the output from the pump.
However I noticed the pump exit hose line terminates at a brass fitting coming up from the floor that appears to be attached to the PEX lines but also it goes down into the floor and what?
Isn't my fresh tank located under there and why would the pump be pumping water back into the tank? The fitting is in the floor right where the flexible from the pump attaches to the PEX supply to rest of trailer? Can anyone explain where the other part of this brass T fitting goes to or is coming from? thanx

Re: Winterizing question...

Jim, I installed a fresh water bypass line into my 19 ft recently. the clear water line going into the drivers side of the pump is the inlet and due to the tight space I had to cut this line and get brass barb fittings from the homedepot that threaded onto the valve for the bypass hose. Then I clamped the hose onto the barb fittings with worn gear clamps. This is only drawing water from the tank so it is not pressurized so I felt the worn gear clamps would be fine.

Re: Winterizing question...

Hi Jim

There is always this option, its a pump that pumps the antifreeze in through the city water connection, can't get much easier then that.
Its called the Aqua Pro Pump Kit:- http://www.go-rv.com/coast/do/catalo...62&pageNum=-60
Hope this helps
Doug

Re: Winterizing question and unknown hose hookup

One line I think goes out of the pump is the low point drain. Under the trailer it is located by the water tank.

Re: Winterizing question and unknown hose hookup

All I ever do is to use the low point drain (the line indicated by Chuck). Works great. Can't see any reason to do anything else.

Just before our last trip I did the sound dampening output line (including additional foam padding under the pump), changed out the pump intake line to a reinforced one, and added an accumulator tank.

The pump is quite a bit quieter, and we get at least two evening flushes with the pump off due to the accumulator tank.

A fairly easy job to do.

Please excuse the crappy cell phone shots.





BTW, because the hose kit came with two hoses, and only one is needed, I have an extra flex hose I will send out to the first person who PM's me there address.

Re: Winterizing question and unknown hose hookup

So you removed the pump off the refer wall, installed your accumulator there and put the pump on the floor? Seem's easy enough. My plumbing is a little different but I'm talking about that piece that disappears thru the floor, is that the low point drain? Is there another one for the hot water lines? I guess it is time to start crawling underneath.

Re: Winterizing question and unknown hose hookup

Yeah, that is what I did. And yes, that line that goes through the floor is the low point drain. Hot and cold both will drain back with the water heater bypassed, you just have to drain the water heater separately as you would with any winterizing method.

Re: Winterizing question and unknown hose hookup

Okay, just returned from outside, I have my fresh tank valve and one pipe with a screw on, I assume this is the low point drain. I have the foam package so everything is covered underneath except for the tank valve and this one pipe with a screw on cap. This is my low point drain? Is this for both hot and cold or is there another one underneath the foam some where?

Re: Winterizing question and unknown hose hookup

Okay, this is all now making sense, one low point drain for the entire trailer, hot/cold and one drain for fresh tank. Gotcha, thanks

Re: Winterizing question and unknown hose hookup

On my winterizing list I have some additional steps, perhaps you are already doing these:

- Remove the hot water anode rod, inspect, drain, flush with hose and reinsert with teflon tape.
- Run pump for 30 seconds with low point drain open.

I do not beleive the hot water tank will drain without removing the anode rod.

I have attached my complete instructions in .pdf, the source is Reace and the instructions describe the second of two methods.
