Called out to complete sold work for installment of expansion tanks for two tankless water heaters and a pull and reset on a toilet. Began by shutting off water to the home draining the system. Once system was drained Installed new shut off and mini expansion tank for both the tankless water heater in the garage and in the walk-in attic upstairs. Once work was complete re-introduced water to the system and tested for leaks and functionality. No leaks and everything is functioning properly. Also did a pull and reset on a toilet in the master bathroom due to one of the bolts being broken. Front of the flange was in good condition to replace the bolts with a new wax ring and reset the toilet. Once the toilet was set, tested for leaks and functionality. No leaks and toilet is functioning properly. Thank you for trusting TE certified with all your plumbing needs
