Abstract
A drainage device and method of decreasing clogging in a drain pipe comprising heating the drain pipe with a heating element that is partially enclosed.
Claims27
A drainage system comprising:
- (a) a center drain line for receiving waste liquid;
- (b) one or more outer hot water supply lines for receiving hot water and heating said center drain line;
- (c) said center drain line and said hot water supply lines being comprised of a single elongated tubular member;
- (d) each of the hot water supply lines of the elongated tubular member being plugged at an end;
- and
- (e) each of said hot water supply lines communicating with said center drain line to enable flow of said hot water through said hot water supply lines and into said center drain line.

A drainage system comprising:
- (a) a center drain line for receiving waste liquid;
- (b) one or more outer hot water supply lines for receiving hot water and heating said center drain line;
- (c) an adapter coupled to said one or more outer hot water supply lines, said adapter also connected to a hot water source;
- (d) said adapter comprising a lower inlet half having an inlet port and a lower center orifice, and said adapter also comprising an upper outlet half having one or more outlet ports connected to a circumferential channel and an upper center orifice;
- and
- (e) said lower inlet half including a check valve ball and spring to prevent water from flowing back into the inlet port.
3 more elements
A method for decreasing the rate at which a drain pipe is clogged, said method comprising the steps of:
- (a) providing a drain line;
- (b) heating at least a portion of said drain line with a heating element comprised of hot water enclosed in a hot water supply line adapted to receive the hot water;
- and
- (c) said hot water first flowing through said hot water supply line and subsequently flowing through said drain line.
