3 handle shower valve leaking non stop. Gave various options to rebuild/replace. Customer who called us is the tenant and not the homeowner. Job Will require removing the stems and taking them to supply house to try and match them with a rebuild kit. Only specific supply houses even have rebuild kits available as these style shower valves are very old and no liner to code. Original manufacturers do not make the repair parts anymore. Have to find third party manufacturer rebuild kits.
