  • PEX Pipes, is well known for its adaptability and low maintenance needs.
  • Copper pipes.
  • PVC Pipes.
  • Galvanized pipes for plumbing.
  • Brass plumbing pipes.
  • Cast iron plumbing pipe.

Stainless Steel

Stainless steel, one of the best and most expensive pipe materials, may be worthwhile. Stainless steel is excellent for locations that are prone to rust and are close to sources of water. Stainless steel comes in both flexible and rigid forms, and it has a glossy coating that makes taps and showerheads seem good. It can be used for a range of purposes and is available in a range of lengths and sizes. For pipes and faucets that are readily visible, choose stainless steel.

Pex pipe

Pex pipe

PEX Piping

It is very well known for its flexibility and low maintenance requirements. PEX piping is steadily gaining popularity for both household applications. Although it has a high initial cost, the material is priceless because it requires no upkeep and is easy to install. It is excellent for spreading water all through the house and is leak-free.

Copper Plumbing Pipes

PVC Piping

The most typical applications for PVC piping include the distribution of both hot and cold water as well as sewerage. Depending on its use, it has a range of thicknesses and configurations. For sewer and potable water pipelines, use PVC piping.

Galvanized pipe

Galvanized Plumbing Pipes

Although they were once widely used for residential projects, galvanized plumbing pipes are no longer as common. Gray water and non-potable water can be transported using it, but take care to prevent rust from accumulating inside the smaller diameter pipes.

Cast Iron pipes

Cast Iron pipes

Cast Iron Plumbing

Cast iron pipes are utilized in big water systems because they are heavier. It is mostly installed underground as the primary pipe for drainage and sewage systems, however, it is also available in smaller sizes for residential usage.

Is PPR better than copper ?

Polypropylene pipes are more effective in terms of efficiency, do not lose heat, and have a very low heat transfer coefficient. Copper pipes can be as efficient as PPR pipes despite having a high heat transfer rate with the environment, but only with good insulation, which comes at an additional cost.

Is CPVC better than copper ?

CPVC is incredibly lightweight and simple to install in comparison to copper. Compared to copper, it is less expensive overall, especially given how rapidly metal prices have increased over the previous few years.
