Get your tub plumbing ready for trim with the AB&A™ classic waste and overflow rough-in half kit. Compatible with SCH 40 PVC, this waste and overflow kit gives you only what you need to finish a rough-in installation. The brass strainer fits 1-1/2 in (11-1/2 TPI) pipe and includes a rubber gasket to create a tight seal with the tub. An additional thin gasket is included for thick walled tubs made of material such as marble, as well as a test kit that allows the waste and overflow system to be pressure tested for safety. AB&A™ waste and overflow kits are available in full, half, rough/trim and finish kit configurations and in a variety of finishes to complement today's designs and customer preferences, delivering consistent high quality in both new construction and retrofit markets.
