Winterized BlackJack today....
 
Here are my observations. In following ETI's instructions using compressed air I opened all the faucets and turned on the compressor, problem was I forgot to remove the sink cover and found about 1/2 gallon water on the floor. Also the compressor will not operate with the faucets open, you need back pressure for the compressor to build up pressure. Inside again to turn off the faucets, remove the sink cover and then open close each side to eliminate any remaining water, did the bath sink and toilet. I then removed the fresh water screen and pushed in the relief valve. All is good except I still have water in my line from the fresh water hookup feeding to the pump, everything past the pump is empty. So I hooked up my E-Z Winterizing set up, put the hose in the gal of antifreeze and turned on the pump. About 1/2 disappeared into the lines. Opened each faucet until anti freeze comes out, flushed the toilet and now my tanks are getting some antifreeze as well as my P traps. But there is still clear water in the line from the rear of the trailer to the bypass valve.
Went downstairs and found my hand pump, hooked up to the fresh water intake and opened another gallon and started pumping. However with the hand pump there can not be any pressure, went inside and opened the sink faucet and put in a container in the sink. I pumped about 1/2 the bottle, still clear water in the supply line. Emptied the container back into the antifreeze and repeated, finally the pink stuff started to appear in the clear line feeding the pump. Hooked up the E-Z winterizing hose, turn the valve, turned on the pump and filled the lines again.
I went outside, disconnected the hand pump, hooked up the air compressor, inside to put a container in the sink and started the compressor again, set at 25 psi. Went inside and opened all the lines, captured most of the antifreeze and blew out the lines again.
All in all, about 2 hours and a little over a gallon of antifreeze consumed which is now in the P traps or waste tanks. The other gallon can be used to flush the toilet in winter time use either via the E-Z- winertizing set up or just pour down the toilet. Remember to release that little valve in the fresh water fill, behind the screen and watch out, it spits back.
In retrospect, the low water drain install may have taken care of the water in the line feeding the pump, or a slight more tilt of the entire trailer towards the front may have let gravity feed that water thru the pump, Just a heads up for others when they winterize their 21's. I'd request ETI to put in low point drains right before the water heater in the 21, that should eliminate both the rear fresh water fill line issue as well as draining the front lines.

Winterizing... let's all head SOUTH http://www.fiberglassrv.com/forums/i...lies/winky.gif

Seriously Jim, thanks for the info. I'd appreciate if everyone winterizing would give us all such detailed steps. It seems all the ETI builds have enough differences, the more information the better.

Thanks Jim,

I just realized that I've been sliding around under our 19" but I never saw low point drains. I just checked the Manual and find no mention of it.

In the Pacific Northwest we can usually simply drain the low point and wait to see how cold it gets, then blowing out the remainder if there is a long freeze. All our other trailers had low point drains ... another thing for my to-do list!

OK by me Donna. Texas has plenty of room.:)

I sure am glad for having the old style low-point drain. It took me 1/2 the time to do it, as it took Jim just to write that post. :)

Where is the low point drains located? I'll copy it.

I was puzzled by yellow/greenish pieces of square tape (3/4"x3/4") over what feels like a hole with caulk in it. I have 5 holes with tape and 5 that can drain. The ones that drain are a little bigger then a pencil and none with screen or anything to keep insects from flying in.

Could any of those be for the low point drain that's not there?

Hi Mel,
I am with you I have aften thought the same thing about insects getting into the weep holes. You would think that the holes should be covered by a screen

I don't think the newer 19's have a low-point drain.

The manual may not mention low-point drains because you don't have them. See the Low point drain topic, especially post #13.

Those are weep holes to allow any water/condensation that does get inside to drain. There is a trough around the perimeter and the floor is elevated by design, thus water will collect, if any and these holes allow the drainage. I opened all my taped holes but Reace said it wasn't necessary. The low point drains have a faucet at the end, identical to your fresh tank drain, so if you do not see more than the one on the fresh tank then no more. I know ETI stopped when they changed molds sometime between my 2012 and 2014 models.
