M friend replaced my hot & cold water shower faucet valves and handles (Crane, from the 50's to 70's) with valves that say Lasco - Crane Dialez and some handles which are a different shape than the originals but seem to fit okay. The hot is working fine, but the cold handle now turns counter-clockwise to open (the same as the hot handle). The cold used to open when turned clockwise. Now there is water leaking from the the cold water handle, (the original leak was coming out of the faucet and seemed to be because the handles were no longer able to be turned closed tight enough). Did he do anytthing wrong and how can I fix it? Thanks.
