Abstract:
For a chemical water-treatment dispensing system of the self-metering bypass type for connection to an existing influent-valve and effluent-valve of a pressurized waterline, an advantageous routine maintenance procedure comprising:provided an imperforate canister with a service-cap screw-threaded mounting means for receiving a mating screw-threaded service-cap; the shutting off of both influent-valve and effluent-valve, whereby a pushbutton located atop said service-cap is depressed to conveniently bleed-off prevailing hydraulic-pressure so as to more easily unscrew said service-cap from said screw-threaded mounting means to gain access within confines of said canister for periodic replenishing of its commercially available chemical-compound; the restoring of said service-cap back to said screw-threaded mounting means, then reopening of both influent-valve and effluent-valve members, at which stage the pushbutton is again depressed to this time enable internal hydraulic-pressure to effectively bleed-off any entrapped air from within the upper confines of said canister, at which point the routine maintenance job is thereby completed.
