Looking for a little feedback. I own a summer home in PA mountains. We plan on going there Christmas and perhaps a few times in the winter but not too much. The house has a crawl space where the hot water heater as well as the water well pressure tank is located. I heat wrapped all my pipes and lowered my heat to 50 in the house. I have the water pump off as well as the hot water heater power. After getting my first electricity bill and we have not even hit the cold cold months I am ready to take a different approach for when I am not there. I would like to blow out all the lines and add the marine anti freeze to all the traps and toilets and drain the hot water tank. The house is real small with not too much plumbing so spending15 minutes at the end of any winter trips to winterize the house and save hundreds of dollars a month is well worth it. Now as far as blowing the air into the system this is where I would like a little advise. I blow out my irrigation system and my home each year so I have the hookups and knowledge for that but am confused about the whole house but more importantly the water well pressure tank. I have a outdoor faucet which is right by my garage and by the air compressor. Can I hook up the air line to that and send the air into the system that way? Also what about the pressure tank that the water well sends water into (I am new to water wells, my fulltime home has municipal water) do I have to shut the valve off to that in other words if the air hits the pressure tank will it harm it or do I have to make sure the pressure tank valve after the tank is closed. I apologize for the long winded question and I appreciate any feedback.

Is there any way to repair clay drain tile without digging up the hole basement and yard? like some kind of rubberized lining.
