WHY UNDERGROUND DOWNSPOUTS?

UnderGround Downspout Extension Installation Guide

WORKS WITH ANY STYLE OR SIZE DOWNSPOUT

The universal debris filter is designed to accommodate any downspout. No special fittings or connectors needed. Debris filter simply rests below downspout and water free falls into the angled grate.

UnderGround Downspout works during winter months

WORKS YEAR ROUND FROM FREEZE TO THAW

For those living an a cold climate (like us here in Minnesota!), the debris filter becomes the ice guard during the winter. Water free falls into the debris filter beneath the downspout creating an ice break. Unlike other products that connect directly onto the downspout, this ice break prevents ice build up in downspout that could reach roof line and create damage.

REAL PEOPLE. REAL SUCCESS.

Trusted by homeowners and contractors since 1965.

Great product.

Great product and service from this company. We have these installed a few years ago on two downspouts and they work great so we just order 9 more….

Andrew G.

Great way to control rainwater run off.

The Bubbler pop up assembly is a wonderful way to get rainwater away from your home. Once you install this device you can mow over it even with a zero-turn mower without breaking the top.

John L.

Downspout works amazing.

The down spout works amazing. All you need is some pipe and an elbow and some rocks. Better design than any other I’ve seen.
