My Home Warranty Company, American Home Shield (AHS) assigned Third Generation Plumbing (TGP) to check why my tankless hot water's breaker keeps tripping. I talked to TGP's tech on March 9, 2020 when he came to my home and instructed him to call the manufacturer for a diagnosis and determined without first calling the manufacturer doing the diagnosis that the unit needed flushed and that a service port had to be installed at my cost of $350 since it was not covered under AHS warranty terms. Since I am not a plumber, I agreed to the installation.
After the service port was installed on the 16th, the breaker still tripped. I called AHS the following week and they called TGP who informed AHS the port was installed and they were done at my home, they closed out the call. AHS assigned another plumber who came out, and did the proper diagnosis and determined a board needed replaced. When the tech told them the work TGP did, the manufacturer stated the units were designed without the service ports because in having one put on that flushing would cause damage to the unit.
When I called TGP on March 30th, they again told me I had to go through AHS. When I called them out for not calling the manufacturer and doing a proper diagnosis, they stated I was wrong that the in fact did. I called the manufacturer who stated they (Omar) did in fact call on March 23rd and the tech was NOT on site - THIS WAS 2 WEEKS AFTER THE INITIAL DIAGNOSIS of it being hard water and needing a service port installed!
On April 14th I called and spoke to the owner since TGP's office would not provide the number. The owner stated he was not aware and did refund the $350 however I still had to pay an additional $238 to properly plumb the unit to code. I filed a complaint with Florida's Department of Business and Professional Regulation (DBPR) as well as the Better Business Bureau (BBB) to state my experience.
Beware this company!!!
