Abstract:
1. A preemptive method of ensuring the integrity of a water supply system comprising the steps: securing a cylindrical interior surface of a fitting to a cylindrical exterior surface of a pipe having a sealant thereon by inserting the cylindrical exterior surface of the pipe into the fitting to form a primary annular joint between the cylindrical exterior surface of the pipe and the cylindrical interior surface of the fitting; sliding a sealing member having an inner annular surface along the sealant on the exterior surface of the pipe that forms the primary annular joint with the fitting to bring an annular end face of the sealing member in face-to-face sealing engagement with an annular end face of the fitting and the inner annular surface of the sealing member into engagement with the cylindrical exterior surface of the pipe proximate the annular end face of the fitting to form a secondary joint between the pipe and the fitting with the secondary joint on the inner annular surface of the sealing member being in cylindrical alignment and in series with the primary joint so that if a leak should occur in the primary joint the secondary joint inhibits or prevents water leakage therefrom; and concealing the primary joint between the pipe and the fitting after securing the sealing member thereto.
