No air coming through faucets with winterizing/using compressor

Another newbie winterizing question. Have drained tanks and water heater. Pump is disconnected at input and output. Low point valves are open and quit dripping. Problem: Hooked up air compressor to city water inlet and have tried several times at 40 psi. Can see and hear air coming out through the rear low point drain but have nothing coming through faucets, water or air. Should I have closed the low point drains before using the compressor or something else I'm missing?

Please move this to winterizing section if needed. Can't tell on iPad where it's landing.

Thank you all again.

Close everything up and open one outlet at a time at 65psi. Should clear everything out for you. Don't forget to close up water heater.

After draining, I close all the drains and faucets. Then I open one faucet and hook up the compressor. Once that's blown dry, I close it and open another. Don't forget the toilet and sink sprayer.

and the pump outlet line. hook it back up, you're losing all your air through that big opening.

Follow Aquabud's recommendation.....one at a time starting with highest faucets.

Shower head too...lay it in the tub to drain/blow air thru it.
If the kitchen sink faucet has a filter remove it and pour a little AF down the hole, store filter where it won't freeze.

Don't forget to pour some anitfreeze in the "P" traps, as there is no way to drain them.

It worked! Amazing how much water remained in the lines. Thanks again to all.

Tomorrow is heater bypass and AF through system. What a learning experience, and fun one.

I winterized our AS today as well.

After blowing out the lines, I always run antifreeze through the lines (from the pump bypass line -- I do not disconnect the pump), starting with the bathroom sink hot water, then the shower, then the cold water lines in all locations -- one at a time.

I bit of belt and suspenders, but the antifreeze helps prevent corrosion, and lubricates the valves and the toilet seal. I have been doing it this way for over 15 years without any problems.

Is it ok to pour some antifreeze in the toilet, worried about staining porcelain or damaging gaskets of toilet valve?

Antifreeze will not stain the toilet and will keep valve lubricated.

I remove the shower head hose—both of them—in case any water remains in them and store them inside. It is easy to forget the outdoor shower (and toilet water inlet valve and kitchen sprayer). On our Airstream there is a drain under the 3 water heater bypass valves—open that one to drain water and blow it out too.

I do one at a time as suggested above and leave the water pump connected. I have a bypass kit for the pump and that makes pumping anitfreeze through the system much easier and uses less antifreeze. There is a filter on the pump and this is a good time to clean it. On many Airatreams the water pump is buried underneath a bunch of pipes, wires, etc., and backwards—you can't reach the filter. We had ours reversed and moved forward to access the filter. I then mounted the pump on rubber washers to quiet it—worked a little, but is still noisy. At least I know it is running.

Thanks again, to so many.

Did clean the pump inlet screen. Appreciative of those kinds of reminders.

This rig is new, only a month old (for us although unused 2011). We have used no water nor the toliet, other than for a minimal function check when picking up. Who knows though what was used on the dealer lot. So am trying to be careful.

One question but not urgent: when taking out the hot water heater drain plug, it was quite difficult to begin to budge. Was using a wrench, maybe too big of one, maybe the wrong kind of tool. Ended up three fairly bad cut/bleeding knuckles, cut from a wing shaped vertical piece of metal, in the way.

And the plug ended up, after getting it off, not being quite the neatly shaped hexagon it was, before starting. Any suggestions on a better tool for removing that plug?

Again, tomorrow will be heater bypass learning and antifreeze day, taking out the TV, checking tires and bringing the battery in to warmer situation. Anything else I'm forgetting?

Can't say thanks enough.
