Tenet stated that the upstairs master bathroom and hall bathroom toilets will run constantly Tested both toilet to find no issues with master bathroom toilet but hall bathroom toilet had a failed fill valve. Performed minor rebuild on toilet. While doing a pressure test to see if the PRV had failed found the water heater by the PRV has an expansion tank installed on its side on PEX pipe with no strap just. Small piece of PEX and some zipties holding it up. It has already started to lean. This can cause a failure with the water pipe causing a leak. I recommend replacing the expansion tank with a strap to prevent any issues that may come from it. Job completed. Estimates ready to send.
