Cast iron soil pipe shall be threaded

Most popular and generally specified material for drainage system

Durable, conveniently installed for buildings less than 25 storey high

Used for a well-fitted hub and spigot connections

Recommended when the length of a pipe needed is more than 150cm long wherein cutting is not necessary

Preferred when a piece of pipe needed is shorter than 150cm long; when the pipe is cut, both ends has hub to serve as joint connector

Used in lieu of the single hub to do away with caulking of joints. It is cheaper and easily connected using neoprene rubber sleeves

A cast iron pipe that generally used for building installations

A cast iron pipe used for underground installations

Made of alloy of cast iron and silicon. It is widely used in chemical laboratories, industries where acid wastes are being discharge

Made of Portland Cement. Superior for embedment in concrete structure for having the same material properties

Famous in the years 1950's to 1960's when the demand for wood fiber sewers was at its peak

Cheapest among the sewer pipes

Sometimes recommended for house sewer and for septic tank installation. Light in weight, slightly flexible which could take slight soil movement without danger of cracking or pulling out. Also known as "Orangeburg pipe"

Cast into length of 75cm. Durable for underground installations. Highly resistant to most acid wastes. Vulnerable to root infiltration.

One of the oldest plumbing materials used by Egyptians, Greeks and Roman Builders.

Highly resistant to acid and suitable for underground installation. It is poisonous and injurious to human health

Made out from mild steel, drawn through a die and welded, cast into 6.00 meters long

Easily corroded by alkaline and acid water. Deteriorate faster when used as hot water supply line

Better in quality than the steel pipe. More resistant to acid waste than steel pipe.

One of the most expensive types of pipe. Made of alloy or zinc and copper mixed at 15% and 85% proportion respectively.

Durable and extremely corrosive resistant material. It shall be installed without joints where possible.
