winterizing and air compressor questions

Yahoo Message Number: 6930
Another boring question about winterizing and I hope the group wil endulge me.
I receive all my messages from the group by email so they're not numbered, so if these "basic questions' have already been answered, I do apologize, but I can't reaccess them for review.

Here goes.....

This is the first year I'm winterized myself. I just got a nice little air compressor Sears and plan to run about 40 to 50 PSI into the system.

Here's what I don't understand about blowing out the system.
I have a 36' Intrigue - 2002. I've drained water from the fresh water holding tank and other areas by opening the three "low point" valves located next to my service bay. I followed CC advice and ran the pump for about 5 sec when water finally stopped draining from the tiny 1/2 inch drain tubing from the fresh water holding tank. Then, I released the pressure valve on the hot water tank and removed the white drain plug. Next, I turned off water from the ice maker and disconnected the tubing to allow the while supply line to drain. I then turned on the washer/dryer to "fill" and ran it abit until no water came out.

I forgot to remove the water filter so that's coming next.
Now I understand it's time to blow out the system with compressed air.
My question is about blowing out the lines with my air compresor. Before blowing air into the system, do I close ALL open valves, faucets, low point drains, etc. to make the system a closed system, then apply air pressure at 40-50 PSI and open faucets one at a time, or do I open everything up at the same time and let air fill the entire system? If faucets, etc. are opened one at a time, isn't it possible for water to run from one area to the next as sequential areas are opened? And what about the water pump. Do I turn the water pump on while blowing compressed air into the fresh water line? Do I leave the water pump off?
Any answers today would be appreciated. I'm working on it now and cold weather is in the forecast.

Thanks everyone
Tom

Close all faucets, close the (4) low point drains and reinstall the water heater plug, etc., pressurize the system and then open each faucet ( both hot and cold sides) until you get only air (and maybe a little moisture). Then close faucet and go to the next one. Also cycle valves on toilet, Ice maker and washer if installed. When I pressure the system I also take out the water heater plug to blow out the line to the water heater.

In my 36 foot 2000 Allure I have 3 low point drains behind the panel in the sanitary bay and one low point drain behind a panel on the rear wall of the small wet bay just in front of the passenger side rear tires.

One other recommendation.

Some one else suggested making up screw on fitting for the air compressor connection to the city water inlet value
At Lowes I purchased a male garden hose 3/4 inch to a 1/2 reducing fitting and a 1/2 to 1/4 inch fitting, to which i screwed on a male 1/4 air hose quick connect fitting.
I set my air compressor regulator at 40 lbs pressure and leave it connected and It makes it a lot easier to maintain pressure in the system.

Dick.

Thank you very very much!!!

Do you have a washer/dryer? If so, do you take care of it the same as I do?
In previous motor homes the toilet had a separate water on/off valve. If there is one on my Intrigue I can't find it and there's nothing in the manual about its location.

Suggestions?

Thanks again.
Tom

Tom,

Air pressure should be less than 40 lbs if possible, even 30 lbs would do the trick. I close all facutes and drains and them pressurize the system. Then I open them one at a time, hot and cold until no water comes out. Water will be forced to that opening and out. I am not sure about the Refrigarator's ice maker. You will need to connect it to AC to get the Ice maker to cycle.

Hope that helps.
Paul
