About Backflow Preventer Valve

The model BV-216 is a 3/4″ HIGH FLOW backflow preventer valve, where the inlet and spout outlet are 3/4″, the inside of the ports are rimmed for 1/2″ copper pipe, the outside is a 3/4″ MIP thread, the hand shower port the inside is a 3/8″ FIP, the outside is 1/2″ MIP, brass body. This backflow preventer valve is intended only for Deck/Rim Mounted installation, and when soldering, kip the torch flame away from the body. We recommend not to overheat the valve body. The BV216 is highly recommended for Whirlpool, Walk-in tub or any large Bathtub where the time to filled the tub should be fest. The Flow Rate, delivered about 18 GPM @60 PSI.

The cartridge and all internal components are made from an engineered plastic material. The sealing comprises 2 customer-made parabolic O-ring specially designed to reduce extra dragging force also for a positive seal and a smooth seamless changeover from port to ports, thus eliminating any possibility of water-hammer noise.


If the hand shower hose is directly connected to the BV216 diverter valve and needs replacement, the finished area would have to be damaged to disconnect the hose from the valve body.

Omni Brass strongly recommend using KIT-002-0216 witch is:
One 3/8 elbow, One 3/8×3/8×24″ long stainless Steel hose, One 3/8″x3/8 Coupling, then a special hose with one conical 1/5″ nut x 3/8″ FIM nut(see gallery)
What’s the benefit? Hoses for hand shower tend to break very often by using KIT 002-0216 the entire damaged hose together with the KIT 002.0216 can be extracted through the hand shower holder and replaced with the new hose.
