![]() The flexible copper pipe may also be terminated by flaring its end and using brass flare fittings.Water restrictions are on the horizon, yet close to half of all drinking water in Wairarapa is lost before it gets to the tap. Sections are joined together with soldered copper connectors or copper compression fittings. Copper may also be used for gas piping.Ĭutting and Fitting: Copper pipe is easily cut with a tubing cutter or hacksaw. Flexible copper is used in short runs, for water supply, and for the water supply tubing for refrigerators and dishwashers. Prevalent Use: Rigid copper pipes are used for longer runs of water supply, and in some cases as waste lines in the home. Copper pipe costs as much as three times as much as PEX. Rising costs for copper in recent years have caused PEX and CPVC to be used more frequently. It is also prone to damage, may develop pinholes over time, and can rupture from frozen water in pipes. Copper is a soft metal and can be easily cut and fabricated. Copper has proven itself over the decades to be corrosion resistant and very reliable. Type M is normally used for water supply pipes. The rigid type comes in several wall thicknesses: K, L, and M. If you have ABS pipe, it is cut and fitted using the same methods as for PVC.Īppearance: Dull, copper-colored metal pipe.ĭescription: Copper pipe comes in two types: rigid and flexible. This is ABS (Acrylonitrile Butadiene Styrene) and has largely been replaced by PVC in new construction and plumbing repairs, mostly because it degrades when exposed to sunlight. NOTE: You may notice another plastic pipe used in your home plumbing system-a black plastic pipe. The sections are joined together mechanically, using plastic pressure fittings for later removal, or permanently joined using special chemical solvent. Prevalent Use: Use for sanitary waste lines, vent pipes, and drain traps.Ĭutting and Fitting: PVC pipe is easily cut with a hacksaw or tubing cutter. It is often used to repair sections of broken cast-iron waste pipe as well as repairs to other drain lines. It is a strong, chemical-resistant rigid pipe that is somewhat heat resistant and easily cut and fit.
