Freeze Relief smaller 3 1/4" outside (taller) base

The 3” Freeze Relief protects basements in the event of a clogged or frozen discharge line. This unique product helps to transition from a standard 1 ½” Schedule 40 PVC line coming from your sump pump to a 3” line for maximum flow. Freeze Relief works automatically as an emergency release, allowing water to evacuate outside of the home; rather than overflowing the sump basin and flooding the basement. This small, simple devise will extend the life of the sump pump and could even prevent thousands of dollars in flood damage.
