Common Pipe Materials Used in ResidencesCommon Pipe Materials Used in Residences

Your residence pipes system will certainly have various sorts of piping products for different usages, consisting of freshwater supply, waste drainage, watering, gas pipelines for devices, and so on. Which kind is used in which application will mainly rely on the age of your pipes system? An older plumbing system may be dominated by cast iron as well as galvanized iron, while a new residence will have plastic pipelines of various kinds used practically specifically.

Some plastic pipes utilized in pipes (such as PVC and CPVC) may additionally be used in the airing vent of high-efficiency condensing heaters. Nonetheless, this will certainly be an introduction of pipe products for usage in plumbing applications. These are one of the most common kinds of pipes piping materials found in homes of various ages, what they are used for, and also an introduction of exactly how to cut as well as secure them together. Right here are sorts of plumbing materials made use of in piping for waste lines, supply of water pipelines, as well as gas supply:


Cast Iron
Look: Large-diameter heavy metal pipe, plain black with a rough, multicolor surface area.

Description: Premium sanitary waste drain pipeline that is hefty as well as mutes the sound of moving wastewater very well. This pipeline is strong as well as resilient yet tough to cut– usually requiring an unique reducing tool with sharp chain reducing wheels. Repair services are frequently used plastic PVC piping. Cast iron is hardly ever used in brand-new building; rather lots of use plastic PVC or ABS (acrylonitrile butadiene styrene) pipe.

Common Usage: Usage for primary soil stack waste lines and also air vent pipes.

Cutting and Fitting: Needs sturdy reciprocating saw or a special cutting device called a cast-iron pipeline cutter. Safeguarding cast-iron pipelines and fittings together is done utilizing unique techniques, including lead and also oakum in dirt pipeline joints, hubbed installations or hubless combinings making use of pressure bands, as well as various other methods usually unknown to the house owner.

PVC (Poly-Vinyl Chloride).
Appearance: White inflexible plastic.

Summary: PVC is currently the de-facto basic in-home waste line materials. It is a solid, chemical-resistant stiff pipe that is heat resistant and quickly cut and fit. It is often made use of to fix sections of busted cast-iron waste pipe as well as fixings to other drainpipe lines.

Common Usage: Usage for hygienic waste lines, air vent pipelines, as well as drain traps.

Reducing as well as Fitting: PVC pipe is easily reduced with a hacksaw or tubes cutter. The sections are joined together mechanically, utilizing plastic stress fittings for later elimination, or permanently joined making use of unique chemical solvent.

NOTE: You might observe one more plastic pipe made use of in your home pipes system– a black plastic pipeline. This is ABDOMINAL MUSCLE (Acrylonitrile Butadiene Styrene) and has largely been changed by PVC in new building and also pipes fixings, mostly since it deteriorates when subjected to sunlight. If you have ABDOMINAL MUSCLE pipe, it is reduced as well as fitted making use of the very same techniques as for PVC.


Chromed Brass.
Look: Bright, glossy chrome-finished pipe of larger diameter (more than one inch).

Description: Chromed brass is commonly utilized instead of PVC for revealed waste line applications, such as “P” traps or other drainpipe catches where look is necessary.

Common Use: Revealed drains and catches.

Cutting and also Fitting: Conveniently reduced with a hacksaw, as well as joined with slip fittings.


Chromed Copper.
Look: Bright, glossy chrome completed pipe of smaller sized diameter (3/8″ or much less).

Description: Chromed copper pipeline is often made use of where the look of revealed supply of water lines is important.

Widespread Use: Subjected water supply lines, such as supply tubing for toilets or stand sinks.

Cutting and also Fitting: Quickly reduced with a tubes cutter or hacksaw, as well as accompanied chromed brass compression fittings.


Galvanized Iron.
Appearance: Dull silver-gray rigid steel pipeline.

Description: Galvanized iron pipe was when a prominent method of plumbing water system lines in the house, yet it slowly fails due to rust and also corrosion. Therefore, it is no longer generally made use of and has actually been mainly replaced with copper pipeline or PEX plastic pipeline. Galvanized iron pipeline is difficult to cut and sign up with as well as not easily produced on site by the property owner. Fixings are usually done by replacing the pipes with copper or PEX.

Prevalent Usage: Water lines as well as drainpipe lines in older homes.

Cutting as well as Fitting: Can be reduced using a reciprocating saw or hacksaw. The pipe is signed up with by utilizing threaded galvanized iron fittings.


Copper (Rigid and Versatile).
Look: Dull, copper-colored steel pipe.

Summary: Copper pipeline comes in two kinds: inflexible and also flexible. The stiff type can be found in numerous wall thicknesses: K, L, and M. Kind M is the one generally used for water supply pipelines. Copper has actually proven itself over the years to be corrosion resistant and really dependable. Copper is a soft steel and can be quickly reduced and made. It is likewise prone to damages, may develop pinholes gradually, and also can burst from icy water in pipelines.

Rising costs for copper in recent times have triggered PEX and CPVC to be utilized extra regularly. Copper pipeline costs as long as three times as long as PEX.

Common Use: Stiff copper pipes are made use of for longer runs of supply of water, as well as in some cases as waste lines in the house. Versatile copper is utilized simply put runs, for water supply, and also for the water system tubes for fridges and also dish washers. Copper might additionally be used for gas piping.

Reducing and Fitting: Copper pipeline is conveniently cut with a tubing cutter or hacksaw. Sections are collaborated with soldered copper adapters or copper compression installations. The flexible copper pipe may additionally be ended by flaring its end and also making use of brass flare fittings.


CPVC (Chlorinated Poly Vinyl Chloride).
Look: Dull white or cream-colored plastic.

Summary: CPVC is a cost-effective rigid plastic that is created to endure high pressure and also temperature.

Widespread Use: CPVC is used for cold and hot water piping.

Cutting and Fitting: The pipe is easily reduced with a tubes cutter or hacksaw. CPVC is joined completely together utilizing plastic fittings and also solvent glue, or with hold installations where the pipes may require to be taken apart in the future.


PEX (Cross-linked Polyethylene).
Appearance: Normally blue (cold water), red (warm water), or white adaptable plastic pipe.

Summary: PEX is made of cross-linked HDPE (high-density polyethylene) polymer and is an amazing piping material that has actually remained in usage considering that the 1970s. PEX is strong and also adaptable, enduring temperature levels from listed below 32 F to 200 F. PEX is rust resistant, and also unlike copper pipe, it will not create pinholes. Since PEX is flexible and also uses less connections as well as installations, it is simpler as well as faster to install. The minimized number of needed installations in a PEX system additionally minimizes the opportunity of leakages.

PEX has actually ended up being a favorite of specialists setting up brand-new pipes systems and also plumbers making major upgrades to older systems. Significantly, property owners are also discovering the qualities of PEX pipe.

Prevalent Usage: Supply of water as well as radiant heat pipeline.

Reducing as well as Fitting: PEX is cut and fit with specialized installations as well as tools.


Black Iron.

Summary: Black pipe looks nearly exactly like galvanized iron pipe, except it is darker as well as especially developed for gas applications.

Widespread Usage: Natural gas or propane supply pipelines. It is frequently used for feeding gas supply to the furnace, central heating boiler, or hot water heater.

Reducing as well as Fitting: Can be cut utilizing a reciprocating saw or hacksaw. The pipeline is signed up with using threaded black pipe installations.
