Step-by-Step Instructions:

Step 1: Measure the Area and Replace the Old Elbow

Measure to determine how much gutter pipe is needed (it comes in standard 10' lengths).

With the power drill and a 1/8" bit, loosen the rivets holding the old elbow in place and remove the elbow.

Press a new elbow in place.

Insert a new horizontal pipe into the elbow and make a rough measurement at the other end where it will meet the downspout.

Step 2: Cut and Crimp the Pipe

Cut the pipe at the mark, using a hacksaw.

Use the crimper to crease the corners so the pipe will fit into the elbow.

Step 3: Add the Straps and Remaining Elbows

Attach the three straps to the deck with screws.

Reinsert the pipe into the new elbow.

Add the second elbow and the vertical pipe, which have already been measured and cut as was the horizontal pipe (make it end about 4" from the ground).

Add the third elbow at the bottom of the pipe.
