Hello, I have a question, I printed off instructions on how to winterize using air to blow through the lines then pouring antifreeze down the drains. Question, should a person be able to feel air coming through the line? I used a 30lb psi portable tank and then opened each line separately. Never felt any air coming through the line, is this normal? How long should I let the air run through each line, if I bypassed the water heater should air be coming through the hot water line? After the last camping trip I left all the faucets in the on position after unhooking city water, till I got home, opened up the low water drain and drained the hot water tank before leaving last campground. Put a total of one gallon of antifreeze pink stuff down all the drains plus the toilet. Am I good for the winter? Thanks

did you get water out the various faucets? were the low point drains closed while you were blowing the air? if you open only one faucet at a time you should feel some air flow. it won't be strong but you can feel and hear it. the key thing is if you had water flowing out. this is the air flowing through the line. i let mine blow for a couple of minutes per faucet. i go through all of them and then back around again. perhaps overkill. but the water left in the line does drain back a bit and i hit it again.

I'm a bit confused by your statement of using a 30 PSI portable air tank.

Most portable tanks are small volume. If you charged a portable air tank to only 30 PSI, it would have depleted that 30 PSI in very short order.

It wouldn't have had enough volume to push the water out of even one faucet let alone the entire plumbing system.

Portable Tank

It is an electric air tank so it is constantly recharging the air. No water out of the lines but maybe a few drips. I will check the low point drains to see if it was open.

You should be able to see, hear and feel water coming out. At least a fine mist.
