Abstract:
1. An in-line P-trap chlorinator, comprising: (a) a container having a bottom wall, and first and second lateral walls; (b) a conduit for providing water to the container, the conduit having interior and exterior walls, the conduit comprising a horizontal portion connecting first and second vertical portions to one another, the interior wall of the horizontal portion of the conduit being at least a portion of the bottom wall of the container, and the conduit having an opening that extends through the bottom wall of the container for discharging water into the container, the interior wall of the first vertical portion of the conduit being a lower portion of the first lateral wall of the container, the interior wall of the second vertical portion of the conduit being a lower portion of the second lateral wall of the container; (c) an inlet to the first vertical portion of the conduit, for admitting water to the conduit; (d) an outlet to the second vertical portion of the conduit, for discharging water from the conduit; and (e) support means disposed within the container, said support means including a first and second vertical support walls extending from the bottom wall and disposed on opposite sides of the opening for supporting a tablet of a water-leachable algicide and/or antibacterial substance in an elevated position over the opening; the inlet and the outlet to the conduit being disposed above the support means, and the inlet being disposed above a level of the outlet, whereby a water level in the container is at the level of the outlet to the conduit, so that water flowing through the container would contact a tablet disposed on the support means, and would continue to contact the tablet after flow has ceased, and there would be no backflow through the inlet, the opening in the bottom wall of the container being disposed directly below and between the first and second walls of the support means for the tablet, and the container including an upward-directed lip positioned inside the container and around the opening and between the first and second walls of the support means, and said lip tapering from narrow to wide in an upward direction.
