摘要： A dual union drain valve assembly has one or more reversible check valve inserts in the fitting(s) that are coupled to the drain valve body. The coupling of the fittings to the drain valve body is done using union couplings permitting the easy installation and/or reversal of the check valve insert(s). In addition, the union couplings permit removal of the dual union drain valve assembly from the surrounding plumbing system for service or replacement of the dual union drain valve assembly.

摘要： A residential bathtub or shower is combined with a catch drain or basin below and in proximity with the tub or shower in a unitary structure. Most components of a heat pump are located in the catch basin. A hot water tank is outside of the catch basin but located in the immediate vicinity such as at an end of the tub or above the tub or alongside of the tub. The hot tank includes a heat exchanger that is the heat pump condenser, bringing heat to the hot tank for warming household water. Hot water flows from the tank into the tub or shower for bathing and then drains into the catch basin where heat exchangers remove heat before draining or reuse in flushing a toilet.

摘要： Disclosed is a basement sewer drain pump housing that draws fluid from a drain into a housing, where after the fluid is discharged from the housing and out of the basement. The device comprises a pickup tube having a fluid level sensor, which is placed within a sewer main drain or floor drain. The housing comprises an enclosed volume, a suction tube connected to the pickup tube, a suction pump, and a discharge pump. The pump is activated by a switch controlled by the pickup tube fluid sensor, the fluid is drawn into the housing from the drain and discharged through a discharge pipe. The device operates from outlet or battery and serves as a basement drain pump that prevents fluid and sewage backflow during power outages and plumbing blockages. Another modification provides two donuts to prevent the flow of fluid locking both the floor drain and the main sewer drain. Another embodiment show an inflator to stop the flow of fluids.

摘要： The present invention provides an apparatus for speeding the draining of a bathing vessel, and is particularly suitable for speeding the draining of walk-in bath tubs. The apparatus can be concealed in a corner of the walk-in bathtub and comprises an actuation mechanism to open and close the draining outlet which needs minimal force to be actuated, making it especially suitable for use by elderly people. The apparatus can also incorporate a security by-pass drain to avoid overfilling of the bathtub. The apparatus can be installed in most or all standard bathrooms with few adaptations.
