Pipes Used for Residential Plumbing Systems

These are made of different pipes, and their layout generally follows set local regulations. Unfortunately, sometimes, your home’s plumbing system might be the cause of property damage.

Though all the systems are prone to damage, nothing causes considerable damage like a leak. A pipe leakage is a common reason why most homeowners call a plumber like Expert Plumbing, Heating, Air and Electrical. Here are the conventional materials used for sanitary water plumbing:

Vitrified Clay

This mix of shale and clay is set at elevated temperatures to create an inert ceramic material. Vitrified clay is generally used for gravity wastewater collection since it has an extended lifespan and resists sewage damage. However, vitrified clay pipes are highly prone to root infiltration since they are connected to hubbed fittings and attract tree roots. Bi-annual sewer maintenance is recommended to rid the systems of plant roots before they cause leaks.

Cast Iron

This material makes pipes that can withstand severe ground shifts and are resistant to root penetration. The most significant issue with cast iron pipes is corrosion, which can lead to leaks. Regular pipe inspections are vital to ensure that the pipes remain in optimal shape.


Polyvinyl chloride is currently the most common material for sewer pipes. It is lightweight and impermeable to root penetration. Poor craftsmanship and earthquakes can damage PVC sanitary pipes, but these are generally easy to fix.

Blackwater damage from burst sewer pipes releases bacteria, microbes, and toxins into your home. Also, it might lead to property damage. Professional plumbing installation will reduce the chances of blackwater damage.
