What can I use as a sealer to prevent the trap pipe from leaking, when I install a new one? 29 Sep 2000 at 1:52 am #299082 SylvanLMPParticipant If this is a DWV copper connection use any type of soft solder carefully. If this is a PVC connection use Primmer and the proper solvent chemicals with plenty of ventilation If this is a screwed connection use any type of pipe joint compound or Teflon paste or tape. 2 Oct 2000 at 9:40 am #299083 bungieParticipant Or use the fittings in the packet when you buy the new trap Author Posts Viewing 2 reply threads You must be logged in to reply to this topic.
