Higher the Schedule #, side wall thickness increases Less expensive tubing can be used that has thinner wall: typically this tubing is same OD as brass tubing If you use Schedule 40 the OD of the PVC piping fits the fitting Schedule 40 = 1 1/2” pipe (OD 1-7/8” with thicker wall) - common size type for drain & vent piping.Red brass drains offer more pipe flexibility for special installations However there is no functional difference between yellow or red brass in durability or corrosion resistance. There are two kinds of cast brass: yellow and “red” The RED has more copper.The shoe, overflow head and Tee are cast brass.Note that Gerber supplies brass compression nuts with select models, and plated zinc nuts with the 20 gauge drains.Gerber offers 17 gauge and 20 gauge drains.The higher the gauge the thinner the brass.The thicker the tube, the more durable the drain.Can solder tubing, head, tee and shoe together 1 ½” OD brass tubing connects the cast shoe and overflow to a cast Tee fitting.(Retainer ring supplied, standard)īrass drains are the premium material system for tub drains: the “ gold standard” Thru the Wall Drain: Thru the Wall Drains: available with Lift and Turn seal, locating the Tee behind walls up to 10” thick. Drains with Smooth Tee allows a 90˚ rotation for horizontal installation or back outlet configuration (Suffix -87) Side Outlet: Outlet is to the left or the right side of the Teeīack Outlet: the drain outlet is horizontal, away from the tub. Note that the Gerber Roman tub Pop-Up drain does not have a longer shoe tube as the linkage is not extendable or adjustable.Roman Tub drains are available in all Gerber drain styles.Roman Tub Drain: Luxury tubs require drains to fit deeper wells (up to 20” deep), with the drain often farther away from the walls requiring longer tubing between the Tee and the drain shoe Standard Bath Drain: All-tub drain in tee (fits most 14" to 16" high tubs).ĭrain in shoe: Drain drops down directly from the drain shoe The kind of material it’s made of: plastic or brass How the drain is operated (how to operate the plug) Chicago, New York, etc.The kind of tub the drain is designed to fit Plastic drains and piping are not allowed in some localities due to local codes/ restrictions (i.e.Tubular drains (except trip lever) can be horizontal outlet simply by rotating the tee 90º.ABS is better at handling severely cold temperatures, but it can warp with exposure to direct sunlight PVC is more flexible than ABS, but ABS is stronger and more shock resistant.PVC joints are sealed with adhesive (solvent / weld), ABS can not because the adhesive will attack the ABS ![]() ![]() ![]() The kind of tub the drain is designed to fit
