Works With Any

Size or Style Downspout!

Water free falls into the debris filter and flows underground through the 8 feet of PVC pipe. As water fills up in the bubbler pot the lid raises up to let water evenly flow over onto your lawn.


Drainage slots in the bubbler pot lets standing water filter down into the ground. The solid drain cover will then drop down and seal out grass clippings and dirt.


The center post guides and supports the lid from collapsing under the weight of a lawn mower and from being sucked up by a lawn mower. Easy DIY installation!

How To Install:

Select an area for the Bubbler Pot at least 8 feet from the house in line with your downspout. Dig a hole 8 inches deep and 12 inches in diameter for the Bubbler Pot to set in. Scoop out a shallow trench from the house to the Bubbler Pot, slopping from 4 inches deep to 8 inches deep at the Bubbler Pot.


Using standard 4" thin wall PVC pipe and elbow (purchased separately). Fit one end of the pipe into the Bubbler Pot the other end to the elbow. Hold the Debris Filter up against the house just under your downspout and measure the length of pipe needed to connect the Debris Filter to the elbow. Back fill the trench and around the Bubbler Pot with dirt and tamp down. And you're finished!
