3" Freeze Relief®
Discharge Line

What happens when a discharge line becomes frozen, damaged or blocked by roots and dirt? The water being pumped from the sump pump comes right back in the sump basin forcing the sump pump to work double time. What happens when the sump pump can no longer handle the amount of water filling the crock? The basement floods. You can help your customers by installing a discharge protection device on every job. This is where the Freeze Relief comes in to the picture. The Freeze Relief prevents sump pumps from burning out and the basement from flooding by diverting the water until lines thaw or can be serviced.

Product Overview

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.

Excellent customer service. This is a hard to find product. Other companies will only sell to you if their technician comes out to do the install. Nash had exactly what I needed and got it to me fast without trying to up-sell me on the install.

My waterproofing company uses all your sump pumps, especially the battery back up sumps in our waterproofing projects. Our clients are very happy with the results! I'll be recommending you to some other guys in my area.
