For use in domestic electric water heaters, a replacement (or originally installed) inlet outlet assembly comprising a flanged sleeve adapted to be mounted at the bottom of the tank. The flange portion is provided with a threadably received plug carrying an electric element within the sleeve. Inlet and outlet tubes extend along outer generatixes of the sleeve. A second, closed top cylindrical unit is received on top of the sleeve, extending the sleeve and the outlet tube. A series of double-tube sections, fitting one on top of the other, form extention of the outlet tube and a riser tube for water heated within the sleeve. A valved opening is provided for introducing - and selectively shutting off - the water flow into the sleeve, for replacing the electric element without need to empty the whole tank. The units of the assembly are integrally formed by plastic injection molding. |
