Compressor winterizing

Hi well we are on our last leg of our trip. We have a few questions to get us home. I will put them in separate threads

What kind of compressor should we buy to blow out the water when winterizing?
We always winterized the travel trailer but the mh is different. Thanks

Use the same procedure on the MH as the TT.

As for an air compressor, any that will put up 50 PSIG will work. You will need an adapter to connect the city water connection to the compressor. Walmart sells a plastic one with a Schrader (tire valve) connection.

The motorhome may have a water filter which you wil need to remove and plug.

This advice is absolutely correct. I would recommend one difference though. If you have the shrader valve type of connector as the previous poster recommended you will have to hold the air hose on it while the air is blowing out the water. You can go to an RV sales and get an adapter that is water hose on one end. Male air hose quick disconnect on the other. That will allow you to just set the regulator on the air compressor to 45 or 50 psi. hook the water hose end up to the water hose then just plug in the air hose quick disconnect to the hose and then you don't have to hold anything.

"Any compressor that will put out 50 PSIG " is not really accurate. The greater VOLUME that you can put through the lines will best ensure ALL the water is out of the lines. Greater volume can only be achieved with a compressor with a large tank.

I would also recommend removing all the aerators from the faucets. When I blew mine out it dislodged some lime particles in the system that plugged all the aerators. Luckily all the water blew out but when I started to use water again nothing would come out the faucets. Took a minute to figure that out.
