Critter Quitter Vent Pipe Cover

Critter Quitter® Vent Repair was developed to allow a quick and easy repair of damaged plumbing vents. This is accomplished by a patented internal component that directs rain into the vent pipe keeping the damaged portion dry. No removing shingles, simply cut to match the roof pitch and slide onto the damaged vent. Tighten the screws and the job is complete. 

Plumbing vents are a major access point for frogs, rats, and other animals to enter a home's plumbing and particularly toilets. Critter Quitters® solve this problem with an internal screen that keeps these animals out. Construction is fully injected UV stabilized polypropylene. This is one of the most UV resistant plastics known and will provide decades of protection. The unit comes with embossed pitch lines to make field cutting to match roof pitch quick and easy, and comes with 4 black anodized stainless steel screws to provide a secure mounting. The unit is attractive and can be painted if desired. 

Small - 3 inch or smaller outside diameter including flashing  (generally 1 & 2 inch inside diameter vent pipe)

Large - 4 inch or smaller outside diameter including flashing (generally 3 inch inside diameter vent pipe)

Unlike other products that are either screens or guards that just cover the vent to keep squirrels away, the Critter Quitter® has a patent pending design that takes the rain water and directs it into the vent and out the house drain, thus keeping the area between the outside of the pipe and the damaged flashing from becoming wet. This stops further leakage into the plywood decking.  Its outside shell protects the vent from squirrels, and it is an attractive. addition to any roof. It doesn't require any modification to the existing flashing so it can be used on new or damaged vents. 

To fit your Critter Quitter®, simply follow these instructions. You will need a tape measure or ruler, and a saw. Place the unit on your vent with the pitch lines heading toward the back of the unit to follow your roof.

After you have cut the Critter Quitter® to fit install the four screws into the unit prior to climbing to your roof. These need to be in holes evenly around the unit. Note that the two rows of holes in the back of the unit are higher than the front. This allows for roof clearance for the screwdriver. You can use the lower holes if you have a short vent or either of the two rows if your vent is tall enough.  Place the Critter Quitter® over the vent and flashing. 3 and 4 inch flashing will fit snugly and may require some gentle shaping of the soft lead flashing to get it into the unit. The small 2 1/2 inch flashing will require you to set the unit over the vent and work the screws in evenly to allow adjustment of the Critter Quitter® so that is directly centered over the vent inlet.  Tighten the self tapping screws evenly making sure you put some pressure on the screw as you tighten it so that it will pull itself into the vent material. NOTE: The material of a Critter Quitter® will strip easily; it’s only designed to guide the screw through the flashing and into the vent. So take care not to over tighten.

Each Critter Quitter® has dimples that run the length of the unit. These indicate where the unit is thick enough if another hole location is needed or the hole strips out. Simply drill a 1/8 inch hole at the appropriate dimple and install your screw.

Confirm that your unit is over the inlet to the vent and your installation is complete.
