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.
Completed the oil fired water heater maintenance today. I started off with replacing the oil filter, the nozzle, and the pump strainer. Next I drained down the tank. I pulled out the anode rod and it was almost completely gone. After filling the water heater back up I ran the burner. I performed a combustion analyzer test that checks the unit CO, CO2 and oxygen levels and it was running great. I also performed a smoke test and got zero smoke. I noticed that one of the connections going towards the circulator pump is corroded and starting to drip water so I will add that to the estimate. The slop sink in the garage is leaking water from the hose connection that attaches to the handle so those will need to be replaced.

Emergency no heat oil service call. I found no power to the furnace caused by a corroded neutral wire. I repaired both the line and neutral connections to the furnace. It started up and I verified it stayed operating. Thank you!
Completed the gas furnace maintenance today. The client replaced her own air filter. I replaced the humidifier pad. Checked the wiring connections and the capacitor and everything looked good. I checked incoming and outgoing gas pressures and those were good as well. I found that there was a gas leak at the connection going into the gas valve so I pulled it apart and fixed it. I pulled and cleaned the flame sensor. I noticed that the intake pipe was blocked with leafs inside the unit, so I had to cut that open and vacuum up the leafs and glue it back together with a 2 inch PVC coupling. Lastly, I ran the unit and performed a combustion analyzer test that checks for CO, CO2 and oxygen levels and everything was running great.

I completed the oil boiler maintenance today. I replaced the oil filter, the pump strainer, the nozzle and the electrodes. I pulled the front door of the boiler off and brushed and vacuumed out the heat exchanger. I saw that the relief valve was leaking a lot of water out of it, so I went ahead and replaced the relief valve. I purged all three zones of air and all the returns came back hot. Completed a combustion test as well that checks for CO, CO2 and oxygen levels and everything was running great.
