Customer had a leak behind the dryer from a cold water line coming up from the crawlspace to the back of the shower valve. Was unable to access the water line from the crawlspace. Cut a 6 by 6 rectangle out of the drywall behind the dryer to access water piping. Water piping is quest piping and was leaking from a crimped connection. Repaired line with shark bite fitting. Turned on water at the meter and tested repair by observing pipe under full pressure and while shower valve was in use. Customer also had a pressure assisted toilet that is leaking water slowly down the drain pipe. Gave customer estimate for replacement toilet and water repipe due to quest piping. Thank you for choosing CPI plumbing and heating.
