ABSTRACT:
Leak detector apparatus (40) is provided for use with a toilet inlet valve assembly (12) that includes a float (30) slidable along a vertical post (32), which can be easily installed by a handyman. The leak detector apparatus includes a buoyant body (42) and a mount (44) that pivotally supports the body about a body axis (54) on the float (30). The body has a forward end portion (56) that can engage the post to prevent the float from moving down until a chain device (60) attached to the rear of the body is pulled to pivot the body. The body has a center of buoyancy (80), when immersed in water, which lies forward of the body axis, so when immersed the body urges its forward end portion against the post to prevent the float from moving down. The forward portion of the body can include a metal strip with a sharp edge (74) that "digs" into the inlet valve plastic post. The mount includes a pair of upstanding mount posts (114) that project into air holes (112) on the float.
