The OATEY PBF380 backwater valve is a one-way check valve designed for installation on a building's lateral sewer line to help prevent backups and flooding. This PVC valve allows wastewater to flow out while automatically closing if sewage attempts to reverse direction, protecting basements and lower-level fixtures. Engineered to fit over 3 in. SCH 40 DWV PVC pipe, it functions as a durable solution for residential and light commercial plumbing systems using standard 3-inch PVC fittings.
This backwater valve features a heavy-duty PVC body, threaded brass inserts, and a secure bolted cover. It is suitable for gravity flow drainage applications and is made in the USA.
