Eventually, pipes’ uses have a tendency to blend together. Which type of pipe ought to be used for water distribution, drainage, sewer, and even for the exterior? The solution is not as clear as it might have been in the past once the most important pipes of selection have been galvanized steel or cast-iron.

PEX Pipe

PEX, or cross-linked polyethylene, a pipe is just one of the newest and most popular pipes to hit the pipes market. PEX is used only to supply water. PEX is a pipe that is stiff enough to withstand the pressures of water supply but adaptable enough to weave through walls, ceilings, basements, and crawlspaces. PEX has truly delivered water-supply plumbing into the palms of do-it-yourselfers and professional plumbers.

Two additional kinds of pipes are sometimes found in older houses and are infrequently installed, particularly by do-it-yourselfers: steel and cast iron pipe.

Galvanized steel pipe

Galvanized steel pipe has been used for decades for irrigation, water supply, gas supply, and any variety of different functions. While galvanized steel pipe is still around (especially for gasoline distribution ) it’s far less used and is used for water distribution in new construction or remodel projects. Each end of the pipe is threaded, and individual pipes are screwed into each other with linking joints.

Cast iron pipe has been frequently employed for sewer and other drainage functions. Cast iron pipe remains found in many houses. Cast iron pipe is achievable before the point it rusts completely through. Cast iron is quite heavy and hard to cut. Retrofits tend to substitute cast iron pipe using stiff plastic pipes such as ABS.
