A press-type overflow drainage device for water container includes a lifting control mechanism provided with an up and down movement member and a fixed component with a through hole for the movement of the up and down movement member. The lifting control mechanism provides two upper and lower stop positions. The drainage device includes a horizontal button assembly which is provided with a button, and connected with the up and down movement member through a joint member while the corresponding up and down movement member stops in the upper and lower stop positions. The button has the press-in and stop and pop-up and stop positions at the front and rear of the horizontal position. The button is located at the overflow outlet and can control the drainage device of the water container.

A drain for sanitary fixtures such as sinks, tubs or the like is described. The drain is provided with an automatic overflow mechanism, of the magnetic type, configured to be automatically activated when the water level in the sanitary fixture reaches the maximum level allowed. The overflow mechanism comprises a first magnetic element arranged on a stem of the plug, and a second magnetic element integral with the head of the plug and in-between the base and the first magnetic element. In the raised position of the plug, corresponding to the raised position of the head, the first magnetic element and the second magnetic element are magnetically coupled. When a threshold value of the water pressure acting on the head is exceeded, the first magnetic element and the second magnetic element are automatically uncoupled, causing the descent of the head towards the lowered position, corresponding to the opening of the mouth of the sanitary fixture initially closed by the plug.

The drain preferably further comprises a manual lifting mechanism to lift the plug, configured to bring back the plug to the raised closed position following activation. Preferably, also the lifting mechanism is magnetic.

An accelerated drain system for a walk-in bathtub with a water outlet in a side wall communicates water to a diverter valve biased to circulate the water in the bathtub and movable selectively to communicate water through a reverse check valve to a drain, the reverse check valve biased closed to prevent water flow and movable selectively to allow water flow to the drain, with a controller configured for moving the diverter valve selectively from the second position to the closed position for subsequent use of the walk-in bathtub. A method of rapid draining of a walk-in bathtub is disclosed.

The present invention relates to plumbing fixtures, and more particularly to drain stopper assemblies used to control the flow of fluid through a drain opening of a sink or bathtub. More specifically, the present invention is a novel drain stopper device that can be attached or removed from a drain without the use of tools and without requiring a user to access the space underneath the drain. The device is preferably comprised of a drain stopper head portion having a repositionable push button in mechanical communication with a spring, a shaft and a pair of repositionable jaws such that the pair of jaws are repositioned to grip or release a pivot rod when the push button is repositioned between a first and a second position.
