The Different Types of Plumbing. There are three different types of plumbing systems; sanitary drainage, stormwater drainage and potable water. Each of these systems have their own unique functions and purposes.

Installation is probably one of the most demanding parts of plumbing. Having to install porcelain or cast iron toilets and tubs in an upstairs room requires you to carry the heavy and large item upstairs without damaging it. This can lead to pinched fingers, stubbed toes, and bruises on your legs.

The most common plumbing problems are clogged drains and toilets, leaky faucets and pipes, water heater issues, low water pressure, and a running toilet.

Outdated Pipe Material Cast iron was common up until around the 1960s. If it's still in your house, it needs to be replaced, since the chance of it already corroding and putting toxins into your water (such as lead) is high. Galvanized steel: As iron was phased out, galvanized steel became the top piping material.
