Buying Guide: PVC Drain Parts, Basins and Grates

PVC Elbows, Couplings and Adapters
The P Series Schedule 35 PVC elbow with a 6 in. hub and spigot is made for building drainage and sewer applications. Flo Lock compression adapters and couplings connect to polyethylene, copper tube or PVC pipe. Pro-Span Schedule 40 repair couplings differ from the Schedule 35 items, so confirm the schedule matches your pipe before you order.

Catch Basins, Grates and Channel Basins
Polyethylene catch basin kits with a grate are available, as are 6 in. plastic catch basin adapter plugs. The 5 in. green square drain grate helps collect and remove excess water from driveways, patios and other outdoor areas. Spee-D channel grates come in sizes such as 4-1/8 in. W x 2 ft. D, so measure the channel before you order.

Round Valve Boxes and Covers
Round valve boxes with overlapping covers protect underground irrigation and sprinkler system components. The overlapping cover helps keep dirt and debris out. Compare the box width and height, such as 8-3/8 inch W x 9-1/16 inch H, before you order.
