PVC pipe comes in Schedule 40 and Schedule 80, and the difference is wall thickness. Schedule 80 is thicker and stronger, but that does not always make it the right choice.
The Schedule 40
Schedule 40 is the standard for residential drain and vent pipe, and it is strong enough for most home applications at a lower cost.
The Schedule 80
Schedule 80 has a thicker wall and a smaller inside diameter, and it is used where more strength or pressure rating is needed.
The flow
The thicker wall of Schedule 80 slightly reduces the inside diameter, which can matter for flow in some drains.
The use
For most home drains, Schedule 40 is correct; Schedule 80 shows up in commercial and pressure work. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Oceanside, the code dictates the choice.
The fit
Schedule 80 is thicker outside but smaller inside, so fittings differ from Schedule 40. Mixing them up is a common, avoidable mistake.
