Royal Pipe Systems™ Solvent Weld Sewer pipe and fittings are used for building drainage and sewer applications. We offer 2” - 6” diameter solvent weld sewer pipe with either solid or perforated walls. Solid Wall pipe is used to collect wastewater and storm water from the building drains and convey it to the municipal sewer lateral at the property line. Perforated pipe is used in septic fields and for foundation drainage. We carry a complete line of injection moulded fittings, including bends, tees, wyes, couplings, adapters, cleanouts, bushings and p traps. Our fittings are available in 3” - 12” diameters.
