What could be causing this sound??? 16 Jan 2001 at 8:45 pm #289726 SylvanLMPParticipant 1- Cold water entering this tank could cause excessive condensation dripping on the burners 2- The cold water entering this tank is causing the hot metal to contract and expand as it it cooled/heated Author Posts Viewing 1 reply thread You must be logged in to reply to this topic.
