Rinnai Tankless Water Heater Humming sound / Fix the Rinnai loud hum easily and cheap / part 1

here is a non automotive fix. I found this out a few years ago when the heater started making a large vibration and hum sound when it turns on. Called a shop and a 150 just to look at it and then whatever parts. the first time took about 2 hours, and about 6 dollars worth of compressed air. Fixed the problem and about 5 years later it's back, but it not a part wearing out. Check out the video and my part two of putting it back together. It's worth the savings to try this first. This really is a maintenance thing you'll need to do on a tankless. We are very happy with the build quality of the Rinnai and the savings on our monthly gas bill. If you can go tankless, it's well worth it. Please subscribe and like and ask questions. Part to is the put together.
