GSMS HomeClub plumbing visit. Everything went well. There are only a few repairs that I reccomend and I have sent over in an estimate!
Completed the plumbing visit today. I started off with doing the maintenance on the Rinnai tankless water heater. I started off with running a cleaner through it for 35 minutes. After that I flushed 10 gallons of water through it. I cleaned the water inlet screen which was very dirty. I vacuumed out the inside and vacuumed the filter. I checked incoming gas pressure and that was according to manufacturer specifications. I checked all the fixtures and drains in the house and everything looked great!
I hit the primary control reset and the furnace turned on. I believe a little air must have gotten into the line and locked it out. I bled the air at the pump and watched the unit run for about 20 minutes and everything was working as it should.
No heat emergency situation handled immediately on a Sunday evening. Great service!
