Abstract: A clamp for a sanitary fitting includes a first and a second semicircular part that are circumscribed by a flexible cable tie. Each semicircular part has a concave side and a convex side. A channel is formed in each concave and each convex side. The concave channels accommodate a flange of a sanitary fitting when the first and second semicircular parts are disposed in confronting relation to one another. The cable tie positioned in the convex channels circumscribes the confronting semicircular parts. A cable tie catch slidingly receives a free end of the cable tie when the cable tie circumscribes the first and second semicircular parts. A marker on the cable tie registers with the catch or another marker on the cable tie when the cable tie is under a predetermined amount of tension to ensure that the same amount of tension is consistently applied to the cable tie.

Abstract: A ventilation system for a toilet which functions by drawing air from around the bowl through the original flush holes into the existing overflow-pipe and then into a fan compartment. The fan is activated by manipulating the flush handle upward. Malodorous air is then forced through an exhaust pipe into the sewage line downstream of the gas trap. The fan is deactivated when the flush handle is pressed downward and the toilet is flushed. A water-trap between the fan and the toilet tank prevents the malodorous air from escaping into the tank. The water in the water trap is changed with each flush by redirecting the refill tube into the water trap. This prevents the water in the water trap from becoming stagnant.
