The need for a device to prohibit small critters, snakes geckos, roaches, frogs, toads etc., from entering the residence through air conditioner condensate drains and other small discharge drains.
A device that when attached to the existing Poly Vinyl Chloride (PVC) discharge drain piping at the exterior of the dwelling, allows water to exit normally without allowing little creatures to enter the orifice.
Drawing 1/2 shows a tube like device with cap on one end and 6. a series of smaller diameter tube like projections on the other end for connecting to various size piping. The drawing shows a 6″ long section of the tube with 2.38 millameter holes totally around the circumference at one quarter inch intervals both ways. The removable cap also has similar perforations.
Drawing 2/2 shows typical connections to Poly Vinyl Chloride (PVC) piping by friction fit into an existing one half inch pipe protruding to the exterior of the house wall. This device, as shown, can be attached to larger size piping, up to one inch and a half, by simply cutting off the smaller unused protrusions and inserting into coupling.
The device, CRITTER STOPPER, when installed on unprotected open ended Poly Vinyl Chloride piping that vents or discharges to the outside of the residence, such as condensate piping from the air-conditioner, perimeter floor gutter drain systems in screened in lanais, swimming pool water lowering conduits and most other small protuberances can significantly deter the entrance of snakes, frogs, toads, roaches, geckos and many other CRITTERS. The CRITTER STOPPER is a 47.5 mm plastic tube, 232 mm in length, with 2.38 mm holes completely around the circumference and on the cap end, spaced at quarter inch intervals. These holes permit the uninterrupted flow of water without allowing the critters to enter the dwelling.
The cap as well as the entire unit can be quickly removed and flushed with a hose to remove any sediment that might occur within the device. Installation of the CRITTER STOPPER is easily installed to standard Poly Vinyl Chloride pipe fittings and can be orientated either horizontally or vertically as the situation warrants.
