More About Backflows

Because of the risk of the device becoming frozen, therefore not functioning in emergency situations, the answer is no. Codes will not allow it.

When a backflow preventer is being supplied for periods of over 12 hours or more, the term applies. An example is Laboratory faucet equipment, wherein the non-pressure, atmospheric anti-siphon vacuum breaker is being periodically turned on and shut off. Never subject a vacuum breaker to continuous pressure unless it is of the continuous pressure type and clearly identified for this service.

It is possible, but it all depends. An anti-siphon vacuum breaker must be elevated above the sillcock to operate properly. So elevated piping up to the vacuum breaker and down to the sillcock is normally not a feasible installation. However, a hose bibb vacuum breaker can be attached directly to the sillcock, without plumbing changes, and at little cost.

Backflow back-siphonage is the reverse of normal system flow caused by negative pressure in the supply piping; vacuum or partial vacuum.

Backpressure is the reversal of normal flow in a system due to an increase in the downstream pressure above that of the supply pressure.
