The upstairs bathroom under sink drain piping was back pitched towards the trap, I reccomend replacing the drain piping. The upstairs bathroom faucet has an aerator cap that leaks. I tried tightening it but the threads are no good on it. The upstairs bathroom tub spout diverter doesn't seal and the shower valve cartridge does not seem to seal when in the off position. The basement bathroom toilet is wobbly, I tried tightening the flange nuts but they are plastic and will not tighten enough. The basement bathroom sink drains very slowly due to not having a vent.

I replaced the expansion tank and relief valve which had both failed. I diagnosed the humidifier that was not working. The flow restrictor was clogged. I replaced the humidifier pad as well. I resent the estimate to replace the check valve for the basement heat loop. I also will get back to you in regards to the third zone above the garage once I talked to the install team and system replacement designer. Thank you.

Everything went well with the maintenance on your Rheem furnace. I only had to adjust the low fire gas manifold pressure. I found fitting on the vent pipe to have a small leak that had condensation on it. I taped the fitting for temporary fix but I will send an estimate for the repair.

The HomeClub heating maintenance visit went great! I went through each furnace and checked safeties, cleanliness, electrical connections, and gas pressures according to manufacturer specifications. The Bryant furnace in the attic did not require any adjustments. The Whirlpool furnace in the basement needed a slight gas adjustment. Both air filters looked clean so I did not replace them. Thank you and see you next time!

Cleared the kitchen drain with snake and used the rest of the drain after I pushed the blockage out into the main. We ran water and tested operation. I recommend replacing the copper drain tail piece as the bottom is brittle and breaking.

Repaired a Navien NPE-240S tankless water heater with an issue of inconsistent hot water supply near Amherst. Diagnosed the problem as a malfunctioning flow sensor. Replaced the faulty sensor with a new OEM part and cleaned the heat exchanger to remove scale buildup. After reassembling the unit, performed a system check to ensure consistent water flow and temperature stability. The heater is now operating correctly and the customer is pleased.

Completed a water heater installation in Amherst using customer purchased AO Smith ProLine XE 50-gallon gas model. Removed the old unit, installed the new heater on a stable platform, and connected the water supply lines with new brass fittings. Set up the 3-inch venting system to ensure proper exhaust and connected the gas line with a secure seal. Filled the tank and tested the system for leaks, then adjusted the thermostat for optimal performance.
