Drain cleaner apparatus

A float switch apparatus configured to be coupled to a condensate drain line of an air conditioning system, the float switch apparatus comprising:

• a support housing configured to couple with an opening of the condensate drain line;
• a drain cleaner float switch attached to the support housing such that the drain cleaner float switch is configured to positioned in the condensate drain line in response to the support housing being coupled with the opening of the condensate drain line, the drain cleaner float switch configured to be actuated to transmit a float switch signal in response to a presence of fluid in the condensate drain line;
• and
• a supply conduit extending through the support housing, a first end of the supply conduit configured to be coupled in fluid communication with an apparatus outlet of a drain cleaner apparatus, a second end of the supply conduit configured to be in fluid communication with the condensate drain line, such that the supply conduit is configured to establish fluid communication of the apparatus outlet of the drain cleaner apparatus with the condensate drain line through at least the supply conduit to enable a supply of cleaning composition from the drain cleaner apparatus to the condensate drain line through the float switch apparatus,
• wherein the drain cleaner float switch and the supply conduit are offset from a central axis of the support housing.
