Claims23
A filterwell cartridge comprising:
- a housing having a dispersant chamber therein with said housing including at least one vent extending from the dispersant chamber within the filterwell cartridge to a region outside said filterwell cartridge;
- a base located on said housing with said base having a rim with the rim having a first arcuate face C1 and a second arcuate face C2 with the first arcuate face forming a first compound face and the second arcuate face forming a second compound face with the first compound face located diametrically opposite the second compound face;
- and
- a rim base face on said housing with the first arcuate face C1 and the second arcuate face C2 located at an angle with respect to the rim base face so that engagement of the first compound face and the second compound face with a filterwell cartridge holder resists displacement of the filterwell cartridge with respect to the filterwell cartridge holder.
A filterwell cartridge positionable below a water line in a filterwell with the filterwell cartridge comprising:
- a rigid housing having a dispersant chamber therein;
- a vent in said housing;
- a base located in said rigid housing with said base having a first compound face and a second compound face each having a portion containing an acutely angled face for positionally maintaining the filterwell cartridge below a water line in a filterwell through lateral engagement of the first compound face and the second compound face with a dispensing cartridge holder;
- a set of ribs for engagement with the dispensing cartridge holder;
- and
- a set of openings located in said base to control water flow into or out of the dispersant chamber in the housing.
A method of controllably delivering a dispersant to water within a filterwell comprising:
- placing a filterwell cartridge housing having a vented chamber with a dispersant therein into the filterwell;
- engaging a first arcuate face on the housing with a filterwell cartridge holder;
- and
- engaging a second arcuate face on the housing with the filterwell cartridge holder to support the filterwell cartridge in a dispensing condition proximate a water filter located within the filterwell.
