Watts 790203 – Frequently Asked Questions
1) Can Watts Brownline 790203 polypropylene pipe handle acid waste from a lab sink?
That is what it is built for. The 790203 is a 2 inch acid waste drainage pipe in polypropylene, sold in 10 foot lengths, for chemical and lab waste lines where standard DWV materials would be attacked. Polypropylene is the body material throughout, not a lining, so the full wall thickness is the corrosion barrier.
2) Will 790203 Brownline pipe glue to PVC drainage with solvent cement?
No. Polypropylene will not solvent weld. The 790203 is PP acid waste pipe, and PP systems are joined by fusion or by mechanical joints made for the system, so you cannot cement it to PVC or ABS. Where a PP acid waste line has to meet a PVC or cast iron sanitary line, that transition is made at a fitting or coupling rated for it, not with glue.
3) What is the actual outside diameter of 2 inch Watts Brownline acid waste pipe?
2.38 inches OD on the 2 inch size, with a 0.15 inch wall. Those two numbers are what you need when you are checking hanger and clamp sizes, sleeve and core openings, or clearance in a chase. Nominal 2 inch pipe never measures 2 inches on the outside, so size your supports to 2.38.
4) Is Watts 790203 the same pipe as the rest of the Brownline system, so my fittings match?
Yes, it is part of the Watts Brownline PP piping series, so it is dimensionally matched to the Brownline PP fittings in the same 2 inch size. Keep the whole acid waste branch in one manufacturer's PP system rather than mixing brands of polypropylene, since joint geometry is what makes the system work.
5) How much pipe do I get per stick, and how do I figure quantity for a lab waste run?
Each length of 790203 is 10 feet of 2 inch pipe. Take your total developed length of 2 inch acid waste, divide by 10, and round up, then add for cutting waste at each fitting and for the stub lengths at sink tailpieces. Fittings are ordered separately.
