Confirmed with customer that water was leaking on connection to shower valve. Turned water off to building and removed sharkbite female adapter and replaced with copper female adapter. Turned water back on to building and water is dripping out of shower head. Informed customer we will need to replace cartridge or replace shower valve completely. Customer decided to replace shower valve. Turned water back off to building and removed old shower valve. Installed new kohler shower valve and turned water back on verifying proper function and no leaks present. Thank you for choosing CPI plumbing and heating.
