Can TireMinder Portable Air Compressor Be Used To Blow Out Water Lines

Published 10/15/2026

Question:

I purchased a TM57MR from you a few months ago for my Class A tires. Can I use my TM57MR with an external pressure regulator set to 15 PSI to blow out my water lines for winterizing?

Hey Will, welcome back! Yes, you can use your TireMinder Portable Air Compressor # TM57MR to blow out your Class A's water lines for winterizing. It puts out 1.8 CFM of airflow, so with an external regulator set to 15 PSI and the appropriate blowout adapter, it will work for this application.

Just make sure you're opening one faucet at a time and allowing enough time to clear the water from each line. At 15 PSI it may take a little longer, but there's no reason you can't use the compressor you already have.

Any big trips planned before you winterize?
