A pop-up drain assembly for a sink has drain piping, a stopper in the drain piping, a pivot rod for opening and closing the stopper and tends not to clog because the pivot rod is not within a fluid flow path. In one embodiment the stopper has flow diverter plates that channel fluid flowing through the drain piping away from the pivot rod so that hair, waste and debris does not catch on and accumulate on the pivot rod. In another embodiment the stopper and the pivot rod are engaged through magnetic coupling, and the pivot rod does not protrude into the fluid flow path. The stopper is preferably variable in length for adjustment to fit different distances from the pivot rod to the top of the drain piping.

A drain covering device is described with built in temperature sensors and lights which signal various measured temperatures which are acceptable, cold, or hot for an intended use. The device is easily separable and can be rinsed and stored using an attached suction cup.

This invention is an excess water slot of dimensions conforming to the recognized dimensions to be installed in place of the previous one but with a different inner design and it also works by a totally different mechanism. It was designed to separate pure water from others by a partition in the upper part of the excess water slot extending inside the washbasin and the lower part of the excess water slot ending with 2 pipe outlets one for pure water and the other for turbid water. The upper side means the upper part with drain holes in the middle of the washbasin. This separation is a small wall of 1-2 centimeter height as shown in 3 at (FIG. 2) with small flexible arms of extending ends as shown in 1 A (FIG. 5.) to separate water when it falls from the faucet down to the washbasin, and to allow using rubber taps for each half of the excess water slot. One of the two outlets is directed to the public drain system and the other for recycling, for clarification of the invention.

To provide a drain unit and a wash-basin capable of solving various problems relating to a wash-basin with an overflow hole formed at a bowl part. A drain unit includes a first cylindrical body 10 to be mounted on a drain port 112, a second cylindrical body 20 provided inside the first cylindrical body 10, and a water plug member 30 provided at the second cylindrical body 20. The water plug member 30 is capable of closing an opening of the second cylindrical body 20. A flow path 60 is provided between the first cylindrical body 10 and the second cylindrical body 20. The second cylindrical body 20 has an opening part 24 through which the flow path 60 and space in an inside part of the second cylindrical body 20 communicate with each other.

A method of providing access to a sink by a diminutive person in a public restroom and an individual in a wheelchair. The method comprising providing a sink positioned above the floor and also includes providing an unobstructed frontal approach zone of at least thirty inches in width in front of the sink. A sink access device is provided having a first upright position positioned outside the unobstructed frontal approach zone. In this position, an individual in a wheelchair has access to the sink. The sink access device may be deployed into a horizontal position into the frontal approach zone providing access to the sink for a diminutive person such as a child. The sink access device includes a bias for biasing the sink access device in the first natural vertical position.
