Contractors have told us that our FCN-30V is the perfect solution for tankless water heaters.  On most tankless water heaters, the condensate drain is a 1/2″ nipple.  Simply screw our vertical neutralizer to the nipple and then point the outlet toward the nearest wall and then of course to the drain.  It couldn’t be simpler or more professional.  Pick yours up today!Properly Installed Condensate Neutralizer
