Freezing Discharge Lines

Winters may be hazardous to your crawl space's health. Your sump pump gets the water out of the crawl space and away from your house with a pipe- usually plastic and usually about 1 1/2 inches in diameter. This pipe runs on the surface of the ground, or in a shallow buried trench , and discharges the water onto the surface away from the house. 

The problem is that, in winter, the outlet of the pipe becomes blocked with snow and ice. When the pump runs, it fills the pipe with water. Since the water can't get out of the pipe due to the ice at the outlet, the whole pipe fills with water and freezes. Now your pipe runs, but cannot get the water out, and your crawl space floods. Just what you were trying to avoid! 

DryZone has a solution - The IceGuard System. This is a specially engineered fitting that goes outside your home and automatically ejects the water away from the exterior wall in the event that the pipe freezes. It is designed with holes in it to allow this to happen, yet no water at all gets out of these openings when the pipe is not frozen.
