The installation of an Advanced Valve Technologies EZ Valve ensured a fire and police station maintained their water supply during vital repair works to a fire hydrant. Hydratec Services, a trusted long-term partner of AVT, was called on to assist with the repair of a leaking fire hydrant in an East Texas location. 

Typically fire hydrants are supplied by a T-line. This is a small section of water line that is fed by the main line running along a street. Conventional water valves require a large section of pipe to be available when installed due to the need for at least two excavations for the fitting of line stops and a valve, but the AVT EZ Valve requires just one small excavation allowing them to be fit on this small T-line and isolate the hydrant without affecting the rest of the local water supply.


Hydratec owns the kit required to install AVT EZ Valves so when they learned about the issue, they knew the installation of an insertion valve was the best option.

The leaking fire hydrant could not be repaired under pressure so had to be shut off. This highlighted several issues. The closest isolation point was a good distance from the hydrant so up to three city blocks which included a hotel, several restaurants and retail properties, a police station, and a fire station, would also need to lose their water supply for the repair to be completed.

Hydratec Services sent a team of three water industry professionals to fit the EZ Valve. They took just one-and-a-half-hours to install the EZ Valve on the 6-inch cast iron pipe.

“Many times fire hydrants sit at the end of short pipes leading from water mains so installing traditional line stops is out of the question,” notes Shawn Petty, AVT’s vice-president of global sales. “The AVT EZ Valve can be installed on relatively short pieces of pipe and has time and time again proved itself to be the ideal solution when fire hydrant repairs are required.”


Advanced Valve Technologies is part of ClockSpring NRI, the high-performance critical infrastructure solutions company that provides innovative, tested, safe, and environmentally-conscious asset integrity solutions for construction, maintenance, and rehabilitation of infrastructure assets. 

On the EZ Valve’s use in East Texas, AVT President Harry Gray says, “This is a great example of how the compact, yet robust AVT EZ Valve delivered the perfect solution to a potentially costly and highly disruptive issue. We are seeing more and more water system operators opt for the EZ Valve when they need to shut off fire hydrants for repair and this is a perfect example why.”

The AVT EZ Valve insertion valve, can be installed on water pipelines sized from 1.5 to 24 inches without shutting off the water and in many cases, in under an hour. AVT designs are innovative, minimize risk to the environment, and reduce costly downtime. 


“Our primary focus is on disruptions in water service that cost providers money and leave end users without service,” adds Gray. “Our products are supported by experienced sales, engineering, and manufacturing professionals alongside a robust and all-encompassing training curriculum which means water professionals can become fully certified to install the EZ Valve in just one day.”

The insertion valve can be used in a range of industries such as water and wastewater utilities, onshore, petrochemical and refinery, pipeline and distribution, and tanks and terminals. In addition to fire hydrants, the valve also serves a range of specific applications such valve exercising and the addition of control points.
