Customer called after hearing sounds of water running in the basement. After turning off the main shut off inside, the meter still constantly clocks water movement as well as an audible noise being heard from where the water line penetrates the foundation. These pieces of evidence confirm what seems to be a leak at the penetration. Additionally, upstairs in the master bath, the water closet has a slow seepage leak from the tank to bolts and must be repaired. Customer is not interested in a full service replacement at this point in time.

Client complaint is gray water and particles in the water throughout the building. Tested top floor, master bathroom, where the water was seen as client explained. I can clearly see the water is discolored and particles coming out of the hot water side only. Tested by filling up each sink with cold water first then hot water and clearly there’s a difference. Checked water heaters and client has (2)50 gallon natural gas water heaters that are 12 years old. Recommend client change the water heaters to remedy the Issue. Change the (2)50 gallon natural gas water heaters and tested with no leaks. Documented all work with pictures.

Our client purchased a Toto G5A toilet with bidet and needed it to be installed. The location for this installation is the master bathroom. Once I inspected the toilet flange, I discovered that it was broken. The client gave me the OK to replace it. Replacing proceeded with the insulation of the toilet. The toilet is installed and is operating properly. Client is satisfied.

James Steffey with TE Certified was by far the best electrician we have ever worked with. He listened to our needs and made some excellent suggestions. He worked with us to achieve the most we could with our limited budget. As this was a remodel with no attic access, we worked tirelessly to minimize the cuts needed in the sheet rock to run wiring and placed covers on any cuts necessary. Our townhouse was dark and now we have ample light, beautiful accent lightening, dimmers, and an outlet where we need it in our deck. I highly recommend him!
