Thank you so much for sharing this tip. So much easier and less involved than a chemical flush. Worked great on a heat pump that was giving me problems all summer. Can’t believe this isn’t better known!

What is that contraption you used? Looks like you're pushing air through the lines with water at the same time?

It’s a device we built ourselves. It uses compressed air to clean the system while water runs through it. We’ve been thinking about selling them. Let us know if you’re interested. Go to our website and fill out the form or email us.
