The elongated drain ports extend radially away from the central hub. The surface material individually surrounds the central hub and elongated drain ports when the pool drain is installed in the surface material. Internal dividers are located between the central hub and the elongated drain ports. The internal dividers are positioned so that they direct fluid away from the central hub, around each of the internal dividers and back toward the central hub. A water stop surrounding the central hub and elongated drain ports anchors the pool drain in the surface and prevents leakage. ## Claims ### Claim 1 A pool drain for flush mounting in a surface material of a swimming pool or spa having a pump-driven filtering system, the pool drain comprising: a central hub having an access port, the central hub in fluid communication with the pump-driven filtering system; a plurality of elongated drain ports in fluid communication with the central hub, the plurality of elongated drain ports extending radially away from the central hub; and wherein the surface material individually surrounds the access port and each of the plurality of elongated drain ports separating the elongated drain ports from the access port when the pool drain is installed in the surface material. ### Claim 2 (depends on 1) The pool drain of claim 1 further comprising a removable lid covering the access port. ### Claim 3 (depends on 1) The pool drain of claim 1 further comprising a plurality of internal dividers, each of the internal dividers disposed between the central hub and one of the plurality of elongated drain ports. ### Claim 4 (depends on 3) The pool drain of claim 3 wherein the plurality of internal dividers are positioned to direct fluid away from the central hub, around the plurality of internal dividers and back toward the central hub. ### Claim 5 (depends on 1) The pool drain of claim 1 further comprising a water stop surrounding the central hub to anchor the central hub within the surface material and prevent leakage. ### Claim 6 (depends on 1) The pool drain of claim 1 further comprising a plurality of water stops surrounding each of the plurality of elongated drain ports to anchor the plurality of elongated drain ports within the surface material and prevent leakage. ### Claim 7 (depends on 1) The pool drain of claim 1 wherein the plurality of elongated drain ports comprises four elongated drain ports. ### Claim 8 (depends on 1) The pool drain of claim 1 wherein the plurality of drain ports comprises two longitudinal drain ports oriented along a longitudinal axis and two lateral drain ports oriented along a lateral axis. ### Claim 9 (depends on 8) The pool drain of claim 8 wherein the longitudinal drain ports and the lateral drain ports are substantially narrower than the access port. ### Claim 10 A pool drain for installation in a surface material of a swimming pool or spa, and connection to a pump-driven filtering system, the pool drain comprising: a central hub in fluid communication with the pump-driven filtering system; an arm extending from the central hub, the arm coupling an elongated drain port to the central hub; the arm having an internal divider partially occluding the arm; and the internal divider positioned in the arm to direct fluid entering the elongated drain port away from the central hub, around the internal divider, and back toward the central hub. ### Claim 11 (depends on 10) The pool drain of claim 10 further comprising a removable lid covering the central hub. ### Claim 12 (depends on 10) The pool drain of claim 10 further comprising a water stop surrounding the central hub to anchor the central hub within the surface material and prevent leakage. ### Claim 13 (depends on 10) The pool drain of claim 10 further comprising a water stop surrounding the elongated drain port to anchor the elongated drain port within the surface material and prevent leakage. ### Claim 14 (depends on 10) The pool drain of claim 10 further comprising a plurality of arms, each having an elongated drain port. ### Claim 15 (depends on 14) The pool drain of claim 14 wherein the plurality of arms consists of two opposing longitudinal arms arranged substantially perpendicular to two opposing lateral arms. ### Claim 16 A pool drain for flush mounting in a surface material of a swimming pool or spa having a pump-driven filtering system, the pool drain comprising: a central hub having an access port, the central hub in fluid communication with the pump-driven filtering system; two longitudinal elongated drain ports extending away from the central hub in opposing directions along a first axis; two lateral elongated drain ports extending away from the central hub in opposing directions along a second axis; and wherein the first axis is substantially perpendicular to the second axis. ### Claim 17 (depends on 16) The pool drain of claim 16 further comprising a removable lid covering the access port. ### Claim 18 (depends on 16) The pool drain of claim 16 further comprising a plurality of internal dividers disposed between the central hub and each of the longitudinal elongated drain ports and the lateral elongated drain ports. ### Claim 19 (depends on 16) The pool drain of claim 16 wherein the plurality of internal dividers are positioned to direct fluid away from the central hub, around the plurality of internal dividers and back toward the central hub. ### Claim 20 (depends on 1) The pool drain of claim 1 further comprising a water stop surrounding the central hub, the longitudinal elongated drain ports and the lateral elongated drain ports for anchoring the pool drain in the surface material to prevent leakage.
