4" Freeze Relief


When it comes to basement waterproofing, you have to think of both inside and outside the home. There are many ways a sump pump can fail; one of the most commonly overlooked is the discharge line being clogged or frozen. With the line blocked, water flows back into the sump basin, causing the pump to fail and the basement to flood.

It’s a nightmare scenario that can happen out of nowhere, but you can help your customers by installing discharge protection in the form of Freeze Relief. A simple solution, Freeze Relief is attached to the sump pump discharge line that diverts water from the backed-up line preventing the sump pump from burning out and the basement flooding.

Product Overview

The 4″ Freeze Relief is designed to protect your customer’s basement when their sump pump discharge line becomes clogged or frozen when winter comes on. This attachment is easy to install and transitions a 2” Schedule 40 that comes from the sump pump to a 4” Schedule 30 PVC (thin wall) discharge line for an unobstructed discharge of water from the sump pump.

Freeze Relief is incredibly challenging to clog and works automatically, not having to be monitored. At only 6 inches tall, this low-tech solution prevents high tech problems for your customers by increasing the life span of their sump pump by preventing backfill and even more 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.
