Always call before you dig. US residence call the national call-before-you-dig number 811 a few days before you plan to install. Someone will be out to mark all your utility lines for your safety when digging. 

WHAT YOU'LL NEED:

  • 4-inch thinwall PVC Pipe (10ft)
  • 90-degree PVC elbow
  • Shovel & Gravel
  • Tin Snips

STEP 1:

Select a location at least 8 feet out from the downspout and dig a circular hole for the bubbler pop-up that is 12 inches wide by 10 inches deep. Fill the bottom of bubbler pop-up hole with 2 inches of gravel making sure the top of the green lid will be flush with the dirt line when installed.

STEP 2:

Scoop out a shallow trench from the downspout to the bubbler pop-up hole. For an 8-foot pipe, the trench should start approximately 4 inches deep and end at approximately 8 inches deep.

PRO TIP - Pile dirt on a large tarp to make dirt removal clean and easy.

STEP 3:

Fit one end of the PVC pipe into the 90-degree elbow and the other end into the side of the bubbler pop-up. Set into place and adjust the pitch of the pipe as needed. The top of green lid should be flush with dirt line.

STEP 4:

Mark on your downspout where you’d like the top of the debris filter to be installed - usually between 10 inches to 20 inches above the dirt. Cut your downspout with a tin snips at a 45-degree angle.

STEP 5:

Hold debris filter under downspout and measure the length of PVC pipe needed to connect filter to elbow. Cut pipe
to size and connect one end into the elbow and the other into debris filter.

PRO TIP - Spray paint exposed PVC pipe to match debris filter or exterior.

STEP 6:

Back fill the trench around PVC pipe and bubbler pop-up with dirt and tamp down. Return sod or add grass seeds and you’re finished!
