Our 2″ Tri-Check includes a check valve, union, and ball valve in one fitting. This combination makes it easy to install, eliminating the need to glue all three components together in the field. All parts of the Tri-Check are designed to pass 2″ spherical solids. So, you don’t have to worry about the valve becoming a restriction in the discharge line when paired with one of our sewage pumps. The solvent-weld ends make the Tri-Check easy to install. The Tri-Check’s threaded union makes it easy to remove a pump when necessary. There is no need to cut the discharge pipe to do so. The Tri-Check’s PVC ball valve allows you to completely shut off the flow through the discharge line when needed. This is a handy feature when performing routine maintenance. Additionally, the combination of the check valve and ball valve ensures that you meet the local plumbing requirements in certain areas. Designed for full flow with a clog-resistant design, the 2″ Tri-Check can be installed in a vertical or horizontal orientation. With all of these features, it is an incredibly versatile choice.
