The treatment comprises a dispenser that is configured to couple a stem from a drain extending into a drain pipe. At least a portion of the dispenser is composed of the active agent and thereby dispenses the active agent. The active agent includes at least one of an insecticide, a deodorant, uric acid-consuming bacteria, and an enzyme that digests grease and oil. Thus, problems associated with drains are substantially reduced using the treatment device. ## Claims ### Claim 1 A treatment device for a drain, the treatment device comprising: a skirt valve comprising a stem about which is disposed a skirt, the skirt angled downwardly from the stem to a rim of the skirt; a dispenser positioned in a region (a) below a coupling of the stem to the skirt, and above the rim, such that the skirt protects the dispenser from liquid flowing around the skirt and into the drain; an active agent configured to be dispensed by the dispenser; and wherein at least a portion of the dispenser is composed of the active agent. ### Claim 2 (depends on 1) The treatment device of claim 1, wherein the dispenser is a liquid soluble material. ### Claim 3 (depends on 2) The treatment device of claim 2, wherein the active agent comprises at least one of an insecticide, a deodorant, uric acid-consuming bacteria, and an enzyme that digests grease and oil. ### Claim 4 (depends on 1) The treatment device of claim 1, wherein the active agent comprises at least one of an insecticide, a deodorant, uric acid-consuming bacteria, and an enzyme that digests grease and oil. ### Claim 5 (depends on 4) The treatment device of claim 4, wherein the dispenser comprises the active agent in an amount effective to reduce at least one of odor, insects, uric acid, grease and oil. ### Claim 6 (depends on 1) The treatment device of claim 1, wherein the dispenser comprises an aperture that is sized and dimensioned to receive the stem to couple the dispenser to the stem. ### Claim 7 (depends on 6) The treatment device of claim 6, wherein the aperture comprises threads configured to engage with a threaded portion of the stem. ### Claim 8 (depends on 1) The treatment device of claim 1, wherein the dispenser is configured to directly couple to the stem. ### Claim 9 (depends on 1) The treatment device of claim 1, further comprising a coupler having an aperture, wherein the aperture is configured to receive the stem to couple the coupler to the stem. ### Claim 10 (depends on 9) The treatment device of claim 9, wherein the dispenser comprises a cavity that is sized and dimensioned to receive the coupler to couple the dispenser to the coupler. ### Claim 11 (depends on 9) The treatment device of claim 9, wherein the coupler comprises at least one rib that extends inward to provide a friction fit between the coupler and the stem, and at least one rib that extends outward to provide a friction fit between the coupler and the dispenser. ### Claim 12 A treatment device for a drain, the treatment device comprising: a skirt valve comprising a stem about which is disposed a skirt, the skirt angled downwardly from the stem to a rim of the skirt; a dispenser positioned in a region (a) below a coupling of the stem to the skirt, and above the rim, such that the skirt protects the dispenser from liquid flowing around the skirt and into the drain; an active agent configured to be dispensed by the dispenser; and wherein the dispenser is configured to dissolve to dispense the active agent. ### Claim 13 (depends on 12) The treatment device of claim 12, wherein the active agent comprises at least one of an insecticide, a deodorant, uric acid-consuming bacteria, and an enzyme that digests grease and oil. ### Claim 14 (depends on 12) The treatment device of claim 12, wherein the dispenser comprises an aperture sized and dimensioned to receive a portion of the stem. ### Claim 15 (depends on 12) The treatment device of claim 12, wherein the dispenser comprises a composition that includes the active agent. ### Claim 16 (depends on 12) The treatment device of claim 12, further comprising a coupler having an aperture, wherein the aperture is configured to receive the stem to thereby couple the coupler to the stem, and wherein the dispenser comprises a cavity that is sized and dimensioned to receive the coupler to thereby couple the dispenser to the coupler. ### Claim 17 A method of treating a drain with an active agent, comprising: providing a drain valve having a stem about which is disposed a skirt, the skirt angled downwardly from a top of the skirt to a bottom of the skirt; positioning a dispenser below the top portion of the skirt, and above the bottom portion of the skirt, such that the skirt protects the dispenser from liquid flowing around the skirt and into the drain; wherein the active agent is configured to be dispensed by the dispenser; and wherein the active agent comprises at least one of an insecticide, a deodorant, uric acid-consuming bacteria, and an enzyme that digests grease and oil. ### Claim 18 (depends on 17) The method of claim 17, further comprising using a threaded coupling to couple the dispenser to the stem. ### Claim 19 (depends on 17) The method of claim 17, wherein the active agent comprises at least one of an insecticide, a deodorant, uric acid-consuming bacteria, and an enzyme that digests grease and oil. ### Claim 20 (depends on 17) The method of claim 17, wherein the step of positioning the dispenser further comprises sliding the dispenser onto the stem.
