Completed the oil boiler maintenance today. I replaced the oil filter, pump strainer and gasket and the nozzle. I brushed and vacuumed out the heat exchanger. All of the boiler accessories looked good except for the expansion tank which has failed. Lastly I ran the boiler and performed a smoke test and got zero smoke. I performed a combustion analyzer test that checks the units CO, CO2 and oxygen levels and the boiler was running great. I will send over an estimate to replace the expansion tank.

Manchester, NH - Replaced failed expansion tank and leaking pressure relief valve. Checked for leaks after and there were none. Lastly I ran the hot water and bled all the air out of the lines. The client has a old concrete slop sink in the basement and would like an estimate to remove it and replace it with a new one. The old sink drains directly into the floor.

Completed the Rinnai tankless water heater maintenance. I ran cleaner through it for 40 minutes. After I flushed it with 10 gallons of water. I cleaned the water inlet screen. I vacuumed the air filter and the inside of the water heater. I checked incoming gas pressure and that was according to manufacturer specifications. I completed the plumbing inspection. I checked all the fixtures and drains and everything looked good. I labeled some emergency shut off's and showed the client where they were. I took a look at the furnace and saw that it was leaking water from the collector box. I will send over an estimate to make that repair. Regarding the tub leaking through the ceiling, either the gasket is bad or the drain pipe isn't connected behind it.

I cleaned the water inlet screen. I vacuumed out the inside of the water heater. I checked incoming gas pressure and that was according to manufacturer specifications. I completed the plumbing inspection as well. I checked the fixtures and drains and the only leak that I noticed was the kitchen sink. When ran on cold water it leaks from the handle and the water gets in the cabinet. The client's step son is replacing the sink. I noticed that the house's water pressure was 85 PSI, which is high. I also noticed that the temperature and pressure relief valve on the Rinnai has been leaking. I will send over an estimate to add a pressure reducing valve and to replace the leaking temperature and pressure relief valve.

Completed the house plumbing inspection. Checked all the fixtures and drains and everything looked good. I labeled the water main shut off, hot water heater shut off, and gas shut off's . I found that the furnace was leaking from the inducer coupler due to the hose clamp not being tight. As I was doing the water heater maintenance I found that the vent wasn't connected correctly and it wasn't even tight. I also noticed that the inducer gasket had been tampered with at some point and all that was there was clear silicone. The client wanted to go through with replacing the water heater due to the age and the fixes on the old one. When we come back to do the water heater maintenance have someone check out her master bedroom sink plunger.
