A magnetic flapper flush valve system for toilets may include a flush tube; a flapper arm pivotally engaged with the flush tube, the flapper arm including a balanced counterweight at a first end thereof; a weighted dome attached to a second end of the flapper arm, wherein the weighted dome includes a flapper dome frame and a top magnetic ring attached to a bottom surface of the flapper dome frame; a flush valve base attached to a bottom end of the flush tube, the flush valve base being a tube with a circular upper opening, the upper opening sized and shaped to accommodate placement of weighted dome therein; and a bottom magnetic ring attached to the flush valve base, wherein the bottom magnetic ring is positioned to removably engage with the top magnetic ring when the weighted dome is positioned within the flush valve base.

A dual flush flapper valve apparatus for converting a standard toilet to a dual flush system includes a valve body having a lower rim and an upper rim. The lower rim is configured to selectively engage a tank valve of a toilet. A valve top is coupled to the valve body and is selectively engageable with the upper rim to seal and alternatively unseal a top aperture. A first chain and a second chain are configured to attach to a trip lever of the toilet to move the valve top between a closed position. The first chain and the second chain are arranged such that a partial depression of a handle of the toilet lifts the trip lever to move the valve top to the open position and a full depression of the handle lifts the trip lever further to move the valve body to the lifted position.

The present disclosure describes toilet flappers having an adjustable length cord. For example, the present disclosure describes a toilet flapper having a frame with a guide structure. A float is connected to a bottom surface of the frame. A cap is connected to a top surface of the frame. A retractable cord reel is housed between the cap and the frame. During installation of the toilet flapper, a user can grab a hook attached to the end of the cord and pull enough of the cord out of the retractable cord reel and through the guide structure so that the user can attach the hook to, for example, a flush lever. In some embodiments, the toilet flapper includes a locking mechanism that impedes the cord from retracting back into retractable cord reel or from being pulled out of retractable cord reel by the user.

A device for adapting a flapper of a flush valve of a toilet tank to a valve base with a lateral overflow pipe, includes a fastening element for fastening to the lateral overflow pipe, which has a ring or cylinder shape with a low height and which includes a pair of recesses able to house lugs arranged in the lateral overflow pipe, and which further includes a pair of lugs arranged in opposite positions in a section of the fastening element; and a flapper made up of a flapper body and a pair of arms arranged in the upper portion of the flapper body, the end of each arm including a housing adapted to house the lugs of the fastening part.

A device for adapting a flusher for toilet tanks to a flush valve base provided with a lateral overflow pipe, includes a fastening element for fastening to the overflow pipe, the fastening element having a ring or cylinder shape with a low height and which includes a pair of cut-outs able to house lugs arranged in the overflow pipe; and a support element of a casing of a flusher of toilet tanks, including a fastening arrangement with the casing of the flusher, and may include a part for adapting the diameter of the fastening element to the diameter of the overflow pipe.

This disclosure describes a kit comprising component for removing, replacing, and/or sealing toilet parts. In some embodiments, the kit comprises a flush valve assembly, fill valve assembly, a handle assembly, two tools, two gaskets, and packaging that also serves as one or more water containers. In some embodiments, the two gaskets are two conventional gaskets that can be combined to make a third gasket. In some embodiments, the combination of the two gaskets allows the creation of a synergistic gasket for sealing a tank-to-bowl interface than neither gasket could seal individually.
