Leak detector for use with flanged waste water drain pipe

A leak detector for installation between a gasket and a flange of a flanged drain pipe connection of a wastewater plumbing fixture comprising:

• a flat base sheet bound by opposing first and second surfaces and an outer perimeter, the base sheet defining an aperture sized to be approximately equal to a radial cross-sectional area of the drain pipe;
• a wick material barrier coupled to the base between the aperture and the outer perimeter in a substantially continuous strip around the aperture, the wick material barrier interrupted by one or more gap regions, each gap region defined by a pair of wick material ends;
• a liquid sensor in fluid communication with at least one pair of wick material ends;
• and
• a water-impermeable material coupled to the base sheet and surrounding the at least one pair of wick material ends to form a water-impermeable enclosure defining an interior cavity comprising the at least one pair of wick material ends and the liquid sensor.

• a wick material barrier coupled to the base between the aperture and the outer perimeter in a substantially continuous strip around the aperture;
• a wick material projection extending radially outward from the wick material barrier;
• an absorbent material in fluid communication with the wick material projection, the absorbent material having an absorbent rate greater than the absorbent rate of the wick material projection;
• and
• a water-impermeable material coupled to the base sheet and surrounding the wick material projection to form a water-impermeable enclosure defining an interior cavity comprising the wick material projection and the absorbent material.

• a flat base sheet bound by an outer perimeter and an interior aperture;
• a wick material barrier coupled to the base between the aperture and the outer perimeter in a continuous or substantially continuous strip around the aperture, the wick material barrier interrupted by one or more gap regions, each gap region defined by a pair of wick material projections starting at either end of the gap region and extending radially outward;
• a liquid sensor in fluid communication with the pair of wick material projections;
• and
• a liquid-impermeable material coupled to the base sheet and surrounding the pair of wick material projections to form a liquid-impermeable enclosure defining an interior cavity comprising the pair of wick material projections and the liquid sensor.
