## Description

Product Description 2" x 2" Slip-On Cast Iron Sewage Check Valve From the Manufacturer Save time and material costs with this 2-Inch cast iron slip x slip union. The 30-0151 is simple to install (no threading of pipe is required). The neoprene gasket and flapper are weighted with heavy stainless steel metal backing plates and a stainless steel rivet. This product slips over ABS, PVC, steel pipe or copper piping and can be installed on vertical or horizontal line. It checks backflow of water and sewer gas and reduces motor and pump noise from the plumbing system. The 30-0151 meets the requirements of Wisconsin Uniform Plumbing Code. The flexible neoprene slip x slip union includes stainless steel clamps for low pressure systems. Avoid more than 10-Feet static head above the check valve.

Review: Great valve - Excellent Zoeller product. Cast iron construction is solid and much quieter than the plastic one it replaced.
Review: Works as designed - Bought this again after the original one failed after about a decade of use. The cast iron makes a difference in comparison to plastic and noise levels. Really easy to instal, fit and functionality was perfect. The rubber slip on boots fit tightly and seal good with the stainless clamps.
