Johnson/Thompson "T"
Posted by BAB on July 31, 2002 at 10:29:47:
Ok, I can never remember if it's Johnson 'T' or Thompson 'T', but I'm looking for some installation info on dishwasher vents so I can avoid using an airgap on the sink. How high does the 'T' need to be installed (above sink/dishwasher water level?) and does distance from the dishwasher matter? Thanks for your help.
