HDPE Pipes
They are high-density polyethylene made of thermoplastic material, a product of monomer ethylene. They are among the pipes you should think about for your underground water line needs. The pipes contain non-toxic materials, which do not contaminate water, and hence ideal when piping for drinking water.
PEX Pipes
PEX is an abbreviation for Cross-linked polyethylene. The pipes consist of polymers linked together by a sequence of short bonds. They are manufactured by melting high-density polyethylene polymers giving them relatively much flexibility compared to the others. They are also highly used for underground water lines.
Copper Pipes
Copper pipes are also considered reliable pipes for your underground water line. They are known for their high resistance to leaks, bursting, and corrosion.
PVC Pipes
Polyvinyl chloride, commonly known as PVC, is one of the pipes most people prefer to use for underground water lines. It is a thermoplastic material that ranks among the top three highest manufactured polymerized materials. It is preferred due to its strength, ability to withstand corrosion and rust and a pocket-friendly budget.
