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.

During our visit, the customer mentioned their water heater was leaking for the past couple of weeks. Upon inspection I noticed water was leaking from multiple places on the water heater. I also noticed the water pressure was over 100 psi. Multiple estimates were created and presented to the customer. An estimate was approved to repair these issues. A new 80 gallon hybrid water heater was installed in the garage. This water heater was installed with a leak guard automatic shutoff valve. An appropriate sized expansion tank was installed to accommodate the size of the tank. A condensate pump was added, along with a discharge line that is installed along the garage wall. This line discharges outside in front of the garage. A new pressure reducing valve and main shutoff valve were installed just to the right of the water heater. After installation, I walked the customer through the install. I also was able to help the customer connect the water heater to his phone. The water heater was s

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.
