Sloan Valve EBV-129-A-C G2 Optima Plus Electronic Sensor Module For Water Closet

Good tech support, but you wont need it. It's easy to install. A plumber may charge you $1K

This was exactly what I needed and it's working great!

Great item. Perfect product.

Auto flush valve for stool at office RR. we have several. only negative is that same valve for a water closet stool is not the one used in urnals. The look the same, but means we have to have identical looking spares, that are not interchangeable. But they work great.

Back plate to battery compartment is covered with a electrically conductive material to complete the circuit. When batteries leak acid, the back plate is ruined. Expensive part to just replace the plastic back plate! However, it is what it is and it works as advertised.
