Hydrant Guard is a stainless steel breakaway check valve for wet-barrel fire hydrants.

Our products are patented (U.S. Patents 10,060,101; 11,187,332 & 11,767,923) and easily installed above grade valve attachments that prevent sheared fire hydrants from releasing water surges.

A sheared (broken) fire hydrant can spew thousands of gallons of water per minute onto roads, sidewalks and buildings. Incidents like this are very common, occurring mainly due to automobile accidents.

With a minimal effect on actual hydrant operation, Hydrant Guard goes unnoticed until it’s needed. As soon as a hydrant is sheared, the Hydrant Guard breakaway check valve springs into action. Its valve plates immediately close, effectively sealing the water supply and significantly reducing water loss, leaving only a witness stream as a signal.
