Abstract
A vent pipe cover protective device for a plumbing vent stack having a weatherproofing cover formed substantially of lead material permanently secured over the vent stack. The protective device completely covers the exposed surface of the weatherproof cover so as to prevent access thereto for chewing and consuming any of the lead material by rodents such as squirrels and rats. The upper end of the protective device includes an end piece having apertures such as provided by a screen or mesh material or a drilled plate which are of sufficient size to allow the free upward escape of sewer gas and which are sufficiently small in size so as to prevent, rodents, rats, and other critters such as roaches, birds and snakes from entering into the vent stack itself.
Claims3
For a plumbing vent stack which extends upwardly from a roof from a sewer trap and having a weatherproofing cover open at an upper end thereof and formed substantially of lead material permanently secured over an entire exposed portion of said vent stack projecting above the roof, the lead material being susceptible to being eaten and chewed by rodents, the improvement comprising a replaceable protective device consisting of:
- an elongated substantially uninterrupted sleeve open at a lower end thereof and having a width sufficient for sliding engagement over the cover and a length greater than the width thereof and sufficient to protectively cover substantially an entire length of the cover from rodents that would otherwise have eating and chewing access to the lead material in the cover;
- an end piece having a width such that said end piece is closely received by and securely attached to and enclosing an upper end of said sleeve, said end piece having openings sufficient in size for venting sewer gas upwardly therethrough from the vent stack;
- means positioned between said cover and said sleeve for providing releasable engagement between said protective device and said cover.
A replaceable rodent chewing preventing device in combination with a weatherproofing cylindrical cover open at an upper end thereof and formed substantially of lead material and permanently secured in place over a plumbing vent stack projecting above a roof, the lead material being susceptible to eating and chewing deterioration by rodents, said device consisting of:
- an elongated sleeve open at a lower end thereof and having a width sufficient for sliding engagement over the cover and a length sufficient to protectively conceal the entire length of the cover from rodents that would otherwise have eating and chewing access to the lead material in the cover;
- an end piece having a width such that said end piece is closely received by and securely attached to and enclosing another end of said sleeve, said end piece having openings sufficient in size for venting sewer gas therethrough from the vent stack.
A method for preventing rodents from destructively chewing a lead weatherproof cover which is permanently secured around a generally cylindrical plumbing vent stack which upwardly projects from a roof, comprising the steps of:
- A. providing a roof vent pipe cover protective device consisting of:
- an elongated substantially uninterrupted sleeve open at a lower end thereof and having a width sufficient for sliding engagement over the cover and a length sufficient to protectively conceal the entire cover from rodents which would otherwise have eating and chewing access to the lead material in the cover;
- an end piece having a width such that said end piece is closely received by and securely attached to, and enclosing an upper end and substantially no greater in width than the width of said sleeve, said end piece having openings sufficient in size for venting sewer gas therethrough from the vent stack;
- B. slidingly engaging and securing said device such that said device covers an entire length of the cover.
