Step one on this DIY rainwater assortment system is to divert your gutters.

Your gutters may have current downpipes. You’ll have to take away these and join your PVC elbows. Then, use your PVC pipes to direct the water to the place your first-flush system will likely be.

We’ve used 90° PVC elbows, however you would possibly want 45° elbows as a substitute. Both possibility would work — maintain the scale of your PVC piping in thoughts.

The simplest method to do that is with a chalk line. Set one finish of the road the place the outlet pipe of the diverter is and the opposite the place the tank is. Pull the string again and snap it onto the wall. This may go away a line on the wall that you simply’ll use as a reference.
