ELK Freeze Relief 4" - Use Between 1.5" Sump Pump Line to 4" Discharge Line

Application: Freeze Relief is a sump pump and discharge line protector that helps protect both your sump pump pipes and discharge line pipes from freezing related risks like pipe bursts, pump failures, and flooding

How it works: allows excess water and pressure to escape from the discharge line system to protect against water and pressure backlog that leads to line and pipe damage, pump damage, and flooding

Installation: easily install in-line as the transition between 1.5-in sump pump PVC pipe and 4-in discharge thin wall SDR 35 pipe

Durability: made of high-grade polypropylene (PP) to withstand heavy use and is minimally impacted by the degradation effect of weather; will hold up much better than comparable products made of PVC

Compatibility: Freeze Relief is compatible with standard sump pump 1.5-in PVC pipe and standard 4-in SDR 35 sewer pipe
