Excellent service!

Ben called me to tell me when he would arrive. He was 5 min early. He went to work and did the service I needed done. He checked the transfer box. I told him I hoped I don’t see him until next year. I’m all set for this hectic icy weekend coming up. And another big thanks to Tiffany or Amy who scheduled him on the same day. I’m getting older so I couldn’t remember her name but she was very helpful in getting the service scheduled.

Upon arrival, I was pointed to the garage, utility closet where the water heaters were located. One of the thermal expansion tanks had failed and begun to leak. The water was currently turned off to the home and after providing options for replacement of the thermal expansion tank we did so. After restoring water to the home, we discovered 90 psi, which indicates that the pressure regulator had failed. After providing options, we replaced the pressure regulator. Checked everything for leaks and proper function Note: When the expansion tank leaked, it got the electrical connection for the water heater wet. We checked the upper and lower thermostat and they were dry. There was some moisture in the foam insulation where the water running down the side of the water heater saturated into the insulation. We cleaned out the water where the power connection was and cleaned off the wires. After doing this, we replaced the wire nuts.

Installed two 50 gallon gas Rheem water heaters with expansion tanks, water shutoffs, and new gas connectors. Included the addition of an upgraded anode rod which extends Rheem factory warranty to a 10 year manufacturer’s warranty. We also replaced the home’s pressure reducing valve and set the pressure to 65 psi. We checked to ensure there were no water leaks and used a combustible gas leak detector to ensure there were no gas leaks.

For this job did a leak troubleshoot for homeowner. He has a slab leak on the cold side. There’s water coming up through his carpet however it is nowhere near any of the plumbing groups in his home. I relate to the homeowner that for me to continue with the leak detection, he would need to pull the carpets up and remove some of the flooring and then we could move forward with the leak detection. I did however, isolate his Watermain service to rule that out and multiple other shut offs in the home and attempt to isolate the area.

Upon arrival, customer notified me that they would like to have back up power for the home. Customer stated that he was interested in the ATS, but he didn’t know if it would make sense financially based off the amount of times they lose power in a year. Customer requested that I give him an option for a interlock kit with an inlet box. After having conversation with my manager, we’ve came up with a solution where we can install a separate disconnect next to the meter main combo and extend service wires into this disconnect. We can re-feed our feeder wires back into the main disconnect, allowing the home to be powered properly during an outage and also while using utility services. We cannot lock out the main means of disconnect per conversation with my manager. We will also be giving the customer an option to have whole home surge protection installed. Customer does not have any form of whole home surge protection at the home.
