Customer stated that there was a leak coming from between floors. Cut Ceiling and found that there was a quarter inch copper line going up. Upstairs in hall bath took back panel of shower off and found that on other shower valve service valve was leaking. Replaced O-ring on service valve and tested. No leaks were present at this time. Chen plumbing is not responsible for sheet rock repair or repair of panel for shower/tub combo. Recommended a customer to have shower valve replaced if leak continues.
