The homeowner had a leak at the shut-off valve for the master bathroom toilet. I provided quotes to replace the shut-off valve, and I also noted that the water pressure was unusually high at 80 psi, indicating that the pressure regulator needed to be replaced as well. The homeowner decided to replace all of the stop shut-off valves with new quarter-turn valves. I replaced all the quarter-turn shut-off valves in both the master and guest upstairs bathrooms. Additionally, I replaced the main shut-off pressure regulator and the hose bib shut-off. After installing the new regulator, I set it to the appropriate pressure of 65 psi. Finally, I tested everything and checked for leaks to ensure everything was functioning properly.
