Customer is having issues with fill valve connection on master bathroom toilet. Leak was coming from eroded gasket. Mansfield flush seal was in bad condition and supply line was gray poly. Minor tank rebuild for customer’s toilet. Customer explained brass ball valve on CPvc line leaks. Customer asked me to diagnose it. Gave valve began spraying water out of handle profusely once slightly turned on. Gate valve then did not shut off. Attempted to tighten packing nut and 20+ year-old half inch CPVC snapped. Got reliable restoration out quickly to mitigate water before property damage. Advised customer on better solution for current piping set up. Replaced main shut off valve, PRV and half inch winterization valve for front hose spigot. Drilled two by fours into studs and strapped copper piping and valves down tightly for security and ease of using valves. Pressurize system and tested for leaks. Left estimate for water heater replacement for customer.
