The condensate fluid 186 can generally be water but contain debris and contaminants. Installation of the air-conditioning drain line sanitation device 110 will in general not impede the current flow rate or performance of the drain line 194.

[0043] In related embodiments, use of the air-conditioning drain line sanitation device 110 is not restricted to use on air-conditioning units 180 and systems, but can be installed for any drain line in HVAC systems or other systems from which fluids are emitted, or can be used for any pipe installation with fluid flow, such as industrial pipe systems, for example in the food or chemical industries. The line sanitation device 110 can be used with gravity fed, low flow, or non-pressurized flow pipe lines.

[0044] In a related embodiment, as shown in FIG. 2A, an air-conditioning drain line sanitation device 110 can include: [0045] a) a line connector 210, which is configured as a tee pipe fitting, such that the line connector 210 can include: [0046] i. a connector pipe segment 220, including inner and outer ends 222 224, and a connector aperture 226 in a bottom side of the connector pipe segment 220; and [0047] ii. a container connector 230, which is connected to the bottom side of the connector pipe segment, around the connector aperture 226 [0048] b) a container 112, which is configured to be removably attachable to the container connector 230, for example via a snap lock and/or screw on fitting, such that an interior of the container is in fluid contact with the connector pipe segment 220 via the connector aperture 226, wherein the interior of the container 112 is configured to contain a sanitation composition 214, such that the container 112 can include: [0049] i. an outer enclosure 240, such that an upper end of the outer enclosure 240 is configured to detachably connect to a lower end of the container connector 230 to create a tight lock, for example such that the upper end of the outer enclosure 240 is configured with an enclosure connector 342, such as a snap-lock connector 342 with snap lock tabs 342, as shown in FIG. 3, that can lock into the lower end of the container connector 230. The connection of the outer enclosure is air tight and integrates into existing pressurized operation of the condensate drain line 194; [0050] ii. a sanitation composition 214, which can be positioned in an interior 244 of the outer enclosure 240. As shown in FIG. 2A, the sanitation composition 214 can be configured as one tablet 214, which for example can be a cylindrical tablet 214, such that the tablet 214 is configured to fit inside the outer enclosure 240; and [0051] iii. a sealing plate 260, which is locked in place on top of the outer enclosure 240 between the lower end of the container connector 230 and the outer enclosure 240, such that the sealing plate 260 comprises sealing apertures 262, to allow the condensate fluid 186 to flow via the apertures into 604 the interior 244, as shown in FIG. 6A, such that the condensate fluid 186 mixes with the sanitation composition 214; [0052] whereby, as shown in FIG. 6A, the flow 602 of condensate fluid 186 past the connector aperture 226 will create a drag which causes the condensate fluid 186 mixed with the sanitation composition 214 to flow back 606 into the drain line 190.
