An injector insert for a T-joint

An injector insert 1 for a T-joint 7 comprises an elongate length of pipe 3 having an external diameter DE less than the internal diameter DI of the T-joint 7. The pipe 3 has a collar 5 at one end dimensioned to engage and rest on an internal annular seat 9 of the T-joint 7. The external diameter DE...

Zusammenfassung:	An injector insert 1 for a T-joint 7 comprises an elongate length of pipe 3 having an external diameter DE less than the internal diameter DI of the T-joint 7. The pipe 3 has a collar 5 at one end dimensioned to engage and rest on an internal annular seat 9 of the T-joint 7. The external diameter DE of the injector insert may be between 0.3 to 0.8 times, preferably 0.6 - 0.75 times, the internal diameter DI of the T-joint. The collar 5 may be frusto-conical. The other end 13 of the pipe 3 may be open or closed and may have exhaust apertures 11. The injector insert 1 can be used to convert a standard T-joint into a flange capable of performing the function of a plethora of other flanges. The injector insert 1 can also be used to create an injector Tee with a standard T-joint. This reduces the complexity and expense of many existing systems and substantially reduces the inventory required by tradesmen and retailers. Hot water installations using the injector T-joint are disclosed.
