Installed Hansgrohe shower valve. Reused existing function body and trim. The set screw for the diverter handle is stripped and cannot be removed. Was able to perform work without having to cut handle off but it was difficult. If valve drips from shower heads etc then function body will need to be replaced too which will be an additional charge but shower is work in as it should at this time Initial leak was caused by a split on the hot side of the shower valve. This was plastic male threads that cracked and leaked down into the guest bedroom below Thank you for choosing TE Certified
