Install four lavatory faucets and tested with no leaks. Install new isolation valve at hot and cold water supply in hall bathroom right lavatory . The hot side lavatory supply was crimped incorrectly by the original installer and the cold broke off while attempting to disconnect water supply.

For this job, I worked on troubleshooting lighting circuit to figure out why it was tripping instantly. after doing my thorough electrical inspection, came to find out previous electrician that was hired to install Smart switches, wired two of them incorrectly, causing the dual function breaker to trip. replaced smart switches for two Decora single pole switches In the meantime while homeowner orders more smart switches. left an estimate to replace first floor and all of the house as well, as I explained, they get a better deal per unit. also left a recommendation to install a whole house surge protector, which will improve the safety of their home.

Located the undergoround leak near foundation wall . Client had leak location completed before scheduling repair. Located 1” PVC 3’ below grade level. Pressurized line after excavation and located a cracked 45* turn. Removed the repair couplings and 45 elbow . Installed new PVC pipe with new connection to building supply. Tested with no leaks. The wall was not penetrated with all repairs made outside foundation. Documented all work with pictures. Client has a leak at meter. Recommend client contact water department for repair and a possible prorate of water bill. The excavation side had washed out from the recent water leak. Recommend client go get fresh place sand or topsoil to backfill excavation site. The dirt was put back, but there is obvious soil missing about 6 inches deep from the hole.

Luis was very knowledgeable and explained everything carefully so that I could understand. He also went above and beyond to make sure my electrical panel was up to date and provided suggestions for some items that may need some further upgrades. His work was clean and fast and my charger looks amazing and works! He's also very friendly and humble, and TE Certified is lucky to have someone with his acumen and personality on their team.
