There’s going to be an option to go with a two by three by four gutter adapter or a three by four by four gutter adapter. Those are the two sizes that are the two popular sizes. Make sure you get the right gutter adapter, but outside of that this is going to be super easy.

So, we have a dual wall, nice straight, smooth piece of dual for the cleanout kit. So, nothing can get stuck in there. It’s really like Teflon inside. The gutter adapter is mini culvert pipe. So, you got a piece of mini culvert pipe with your gutter adapter, and your clean out.
We have a 4 inch external snap coupler, so that you connect from this clean-out downspout to clean out and then this snaps onto the dual wall pipe and over the single wall pipe.
It comes with our super sticky, super stretchy tape that is rated to last for 200 years so you can be sure that this doesn’t leak at the house at all. See video to learn where you want to put the tape. If you have any left, then at the far end on the end of the leach field pipe, the knife cut. You want to go ahead and pop the cone in. If you have any tape left, go ahead and secure that.
So, we have our turf restrictor plate with our pop-up and catch basin. You simply run this off the underground downspout, connect it to the solid, run the solid out 15 feet, connect it to the catch basin. Then come out the other side with the knife cut.
Remember all the bulk water is going to go through this knife cut, no problem. There’s no material ground out. Knife cut lives up to its name. It’s just a cut in a pipe, a solid pipe with some cuts. The bulk water is going to travel through this just fine, it’s going to make its way all the way to this pop-up emitter. We got the turf restrictor plate, so this will stop grass from growing over the pop-up. Because that’s number one problem, grass grows over anywhere you daylight your pipe, the outlet. Once the grass grows over it, the water can’t escape. That means the water builds up in the downspout and it just cascades over the gutter trough and ends up flooding your basement. Our turf restrictor plate solves this problem.
So, you got your solid pipe to get away from the house. You go to your catch basin. Then you go ahead to your knife cut, to your pop-up with a turf restrictor plate. All of this is a kit making buried downspouts easy for the DIYer and we can ship it small package.
