How do UnderGround Downspout kits work?

  1. Debris filter removes bulk. As water and debris flow from the gutter, debris is filter out. This allows only water to enter the underground system. 
  2. Water flows to pot. Water flows through underground pipe, entering the downspout pot.
  3. Pot releases water. As the pot fills with water lid raises to release water. If pot doesn’t fill, water drain from the bottom of the pot. 

How To Install:

Underground downspout diverter installation

1. Dig Shallow Trench

Select an area for the bubbler pot at least 8 feet from the house in line with your downspout. You can install further then 8 feet if needed. 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. Tip → Pile the dirt on a large tarp or sheet of cardboard to make dirt removal easy.   Underground downspout diverter installation

2. Connect PVC Pipe & Elbow

Using standard 4″ thin wall PVC pipe and elbow (purchased separately at your local home center). Fit one end of the pipe into the bubbler pot the other end to the 90-degree 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.   Debris Filter Ice Guard Install
