The Under Deck Drainage system is designed to turn the space under your deck into an all weather retreat. You will be able to enjoy the space under your deck in rain because the collection of rainwater will prevent you from getting wet. Installation is designed for the homeowner to be able to do themselves.
Step 1 – Creating a Pitch Line
In order for you to be able to use the space under the deck, you need for your deck drainage system to be able to drain water away. To do this, you need to set the correct pitch line. The best way to do this is to make a mark on the joist near the house. This mark should be measured by 1 inch for every 10 feet of the length of the joist. Pull the chalk line so that it is at the bottom of the joist where the deck ends and at the mark near the home. Snap the line to establish the correct pitch line.
Step 2 – Attaching The Water Diverters
In order to get all water to drain through the deck drainage, you need to attach water diverters between every joist. Attach the diverter at the ledger board. Once in place, seal the diverter to the joist with a bead of waterproof caulking.
Step 3 – Installing The Joist Rails
Using the pitch line, install the first joist rail 1 inch from the home. Continue this process until you get to the end of the joist. Make sure you leave no more than 2 inches in between each joist rail. This needs to be done on both sides of every joist.
Step 4 – Installing Collector Panels
Installing the collector panels is as easy as pushing them into place. Simply start at the end of the home and work your way to the end of the joist. Make sure the collector panel never is able to go flat as you will collect water instead of drain water.
Step 5 – Attaching Gutters
Installing the gutter rails is another very simple process. Simply pull the gutter apart slightly as you push it over the joist. It will firmly snap into place when it attaches to the joist rail. Remember to cut the gutter ¼ inch shorter than the length of the joist to accommodate for expansion. Once the joist gutter is in place, install the boundary gutters which will be used on the two outside joists. These will also snap into place. Make sure you attach the flashing along the edge joist in order to divert water away from you. You will now be able to enjoy the space under your deck any time you want to.
