DWV parts look very similar to standard white schedule 40 PVC pipe and fittings. The only real difference is that DWV PVC is not made to handle pressurized uses like schedule 40 parts are. Instead, DWV pipe and fittings are made to handle a different class of uses – Drain, Waste, and Vent (hence the name DWV).

The main difference between CPVC and PVC is the range of temperatures each is capable of withstanding. CPVC can handle temperatures up to 200° Fahrenheit, while PVC peaks at 140° Fahrenheit.

This is what DWV PVC p-traps do. P-traps are an essential part of any home plumbing system. These p-traps are designed for drain, waste and vent system and are made with durable PVC material to provide a cost-effective and durable option for many applications.

DWV systems remove wastewater and prevent the flow of sewer gases into homes. The most common types of pipe used in homes today are copper and polyvinyl chloride (PVC), which are strong, long lasting and easy to install. Other choices include chlorinated polyvinyl chloride (CPVC) and PEX pipe.

PVC DWV: Have thinner walls. Because of this they are less expensive than schedule 40 PVC.

Drain-Waste-Vent
A plumber will install air chambers or mechanical water hammer arresters to trap the air and cushion the impact the hydraulic shock. Drain-Waste-Vent (DWV) System. The drain-waste-vent system, also known as the sanitary system, is all of the plumbing in your home minus the water supply system.

NOT for compressed air or gasses. 0 (zero) PSI • PVC DWV is NOT a pressure-rated piping system. Recommended test is 10 feet of hydrostatic pressure, which equals 4.3 PSI.

They’re both made from the same form of unplasticised PVC (PVC-U) but the difference is in the wall thickness. Schedule 40 PVC pipes are made with thicker walls that stand up to low pressure applications. Whereas PVC DWV piping has thinner walls and is not made for pressurized applications.

1-1/2 inch
Traps come in 1-1/4 inch (standard bathroom sink) or 1-1/2 inch (standard kitchen sink) inside diameter sizes. Be sure to check so you get the right size replacement at your local store. In this guide we’ll show you how to replace a P-trap in a few easy steps.

Burial of pipe beneath a building built on unstable soil is often accomplished by suspending piping systems from structural slabs. The installation of plastic pipe in such situations must be made in accordance with ASTM F2536 (Standard Guide for Installing Plastic DWV Piping Suspended from On-Grade Slabs).

PVC Schedule 40 DWV Pipe & Fittings. PVC Schedule 40 is highly durable, with high tensile and impact strength. It is easy to install and has better sound deadening qualities than PVC Schedule 40 DWV Foam Core. Installation requires the use of primer and solvent cement. For DWV applications, gradual sloping DWV fittings must be used.
