Abstract
A water backup prevention system is disclosed which has a valve and sensor assembly for being in a first position indicative of a normal condition and second position indicative of a water backup event, the valve and sensor assembly having a device for sensing when the valve and sensor assembly is in the second position and for generating a signal indicative of the water backup event, and a receiver device for receiving the signal indicative of the water backup event.
Claims14
A water backup prevention system comprising:
- a valve and sensor assembly having a top grille, a bottom ring, a flexible seal between the top grille and the bottom ring, a guide pin connected to a float plug, a clamp screw connected to the top grille and the bottom ring with tightening of the clamp screw for expanding the flexible seal, a magnet, the float plug having a magnetic field detector, a control circuit, and a transmitter with the float plug capable of being in a first position indicative of a normal condition and a second position indicative of a water backup event, the magnetic field detector for sensing when the float plug is in the second position and for generating a signal indicative of the water backup event;
- and
- a receiver device for receiving the signal indicative of the water backup event.
A water backup prevention system comprising:
- a valve and sensor assembly having a top grille having a drain hole, a bottom ring having a drain slot, a flexible seal between the top grille and the bottom ring with the top grille, the flexible seal, and the bottom ring forming an upper valve body, a float plug, a guide pin connected to the float plug and the top grille with the float plug being able to move relative to the upper valve body, a clamp screw connected to the top grille and the bottom ring with tightening of the clamp screw for expanding the flexible seal, a magnet positioned on the bottom ring, the float plug having a magnetic field detector, a control circuit, and a transmitter with the float plug capable of being in a first position indicative of a normal condition and a second position indicative of a water backup event, the magnetic field detector for sensing when the float plug is in the second position and for generating a signal indicative of the water backup event;
- and
- a receiver device for receiving the signal indicative of the water backup event.
