Drain line cleaning device and kit

1. A drain line cleaning device comprising:

a male threaded upper portion configured to connect to a source of liquid;

a tapered lower portion coupled to the male threaded upper portion to transfer liquid from the male threaded upper portion to an opening at a distal end of the tapered lower portion; and

an hose connector threaded onto the male threaded upper portion, the hose connector having a first female threaded connector to connect to the male threaded upper portion, a body having a single valve to variably control flow of liquid from the source of liquid through the hose connector, wherein the body is disposed between the first female threaded connector and a second female threaded connector to receive and connect directly to a hose that is connected to the source of liquid,

wherein the tapered lower portion is configured to engage a plumbing connection of an air conditioning system condensate drain line via an interference fit, and wherein the distal end of the tapered lower portion, when engaged in the plumbing connection, extends past an air handler side of the plumbing connection and into an outlet side of the plumbing connection such that liquid flowing from the source of liquid flows through the tapered lower portion and into the outlet side without entering the air handler side of the plumbing connection to flush out the air conditioning system condensate drain line.

2. The drain line cleaning device of claim 1 , further comprising a first end cap inserted into a first opening of the plumbing connection and a second end cap inserted into a second opening of the plumbing connection.

3. A drain line cleaning kit comprising:

a drain line cleaning device comprising:

a male threaded upper portion configured to connect to a source of liquid; and

a tapered lower portion coupled to the male threaded upper portion to transfer liquid from the male threaded upper portion to an opening at a distal end of the tapered lower portion,

wherein the tapered lower portion is configured to engage a plumbing connection of an air conditioning system condensate drain line via an interference fit, and wherein the distal end of the tapered lower portion, when engaged in the plumbing connection, extends past an air handler side of the plumbing connection and into an outlet side of the plumbing connection such that liquid flowing from the source of liquid flows through the tapered lower portion and into the outlet side without entering the air handler side of the plumbing connection to flush out the air conditioning system condensate drain line;

a hose connector threaded onto the male threaded upper portion, the hose connector having a first female threaded connector to connect to the male threaded upper portion, an angled body having a single valve to variably control flow of liquid from the source of liquid through the hose connector, and a second female threaded connector to receive and connect directly to a hose that is connected to the source of liquid, wherein the angled body is disposed between the first female threaded connector and the second female threaded connector; and

a drain line funnel comprising:

an upper funnel to receive liquid poured into the upper funnel, wherein the upper funnel includes an interior wall that slopes from an outer edge toward an opening leading to

a tapered lower funnel portion coupled to the upper funnel,

wherein the tapered lower funnel portion is configured to engage a plumbing connection of an air conditioning system condensate drain line via an interference fit, and wherein the tapered lower funnel portion, when engaged in the plumbing connection, extends past the air handler side of the plumbing connection and into the outlet side of the plumbing connection such that liquid flowing from the source of liquid flows through the tapered lower funnel portion and into the outlet side without entering the air handler side of the plumbing connection, and

wherein the liquid poured into the upper funnel flows through the upper funnel into the tapered lower funnel portion and into a pipe inserted into the plumbing connection.

4. The drain line cleaning kit of claim 3 , wherein the plumbing connection is one of an angled connector, a T-shaped connector, or a four-way connector.

5. The drain line cleaning kit of claim 4 , further comprising a first end cap inserted into one opening of the four-way connector and a second end cap inserted into another opening.

6. A drain line cleaning device comprising:

a male threaded upper portion configured to connect to a source of liquid;

a tapered lower portion coupled to the male threaded upper portion to transfer liquid from the male threaded upper portion to an opening of the tapered lower portion, wherein the tapered lower portion is configured to engage a plumbing connection of an air conditioning system condensate drain line via interference fit, and wherein the tapered lower portion, when engaged in the plumbing connection, extends past an air handler side of the plumbing connection and into an outlet side of the plumbing connection such that liquid flowing from the source of liquid flows through the tapered lower portion and into the outlet side without entering the air handler side of the plumbing connection; and

a hose connector threaded onto the male threaded upper portion, the hose connector having a first female threaded connector to connect the hose connector to the male threaded upper portion of the drain line cleaning device and a second female threaded connector to receive and connect directly to a hose.

7. The drain line cleaning device of claim 6 , wherein the plumbing connection is one of an angled connector, a T-shaped connector, or a four-way connector.

8. The drain line cleaning device of claim 7 , further comprising a first end cap inserted into one opening of the four-way connector and a second end cap inserted into another opening.

9. The drain line cleaning device of claim 6 , further comprising a valve that is adjustable to control flow of liquid through the hose connector.
