Mueller Fire Hydrants

Mueller Systems Announces Fully-Integrated Remote Disconnect

Mueller Systems, a leading provider of innovative water infrastructure products and services and technologically advanced metering systems for water, electric and gas systems, introduced the 420 RDM (Patent Pending: Patent Application No. 13/149,720), a fully-integrated remote disconnect meter (RDM) for the water industry that enables municipalities to remotely manage water services. Mueller Systems is a subsidiary of Mueller Water Products, Inc. , a leading North American provider of water infrastructure products and services, and offers a full line of residential, fire line and commercial meters, automatic meter reading (AMR)/advanced metering infrastructure (AMI) systems and related products that optimize the delivery and use of water and energy.

The 420 RDM enables municipalities to remotely manage water services through AMI networks, such as Mueller Systems' Mi.Net™ Mueller Infrastructure Network for Utilities—from the office or from the safety of their vehicles, helping them to improve customer service, as consumers will not have to wait for a field crew to arrive to turn on their water. Remote service management capabilities provided by the 420 RDM also help municipalities—especially those that experience high account turnover—to improve employee safety, reduce labor and operational costs and lower their carbon footprint, as field crews and service vehicles will not have to be dispatched to connect or disconnect service.

Improved employee safety and customer service as well as the increased operational efficiencies provided by the 420 RDM further enhance the benefits of the Mi.Net System. These benefits include on-demand meter readings, e-mail alerts and alarms based upon near real-time information as well as the ability for utilities to best manage their water resources through on-going access to custom data and information.

Unlike other disconnect valves on the market, the 420 RDM can be quickly and easily installed, as it is fully-integral with 5/8" positive displacement (PD) meters—in standard AWWA laying lengths—without requiring any re-plumbing. And, it can be used for complete water service shutoffs or configured to limit shutoffs to provide Life Sustenance Flow for utilities that have policies against completely terminating water supplies to residential customers.

"The 420 RDM is another one of Mueller Systems' developments that greatly enhance the operational efficiency of municipalities in ways that improve safety and customer service while reducing operational costs," said Hassan Ali, vice president and general manager of Mueller Systems. "Water service providers that use the Mi.Net System can now remotely connect and disconnect water services with this easy to install solution that provides another practical component of this highly efficient network.

MUELLER CO. considers a fire hydrant to be a critical piece of emergency equipment used to preserve lives and property. For this reason all Mueller Fire Hydrants are designed, built and tested to assure high performance and dependability.

Each component part of a MUELLER Fire Hydrant is specially designed to assure proper and reliable operation. Attention to detail doesn't stop once the part is designed. Quality control tests are made on all component parts to assure dimensional and material integrity are maintained. Every MUELLER Fire Hydrant is pressure tested and operated before it leaves our plant to assure it meets our high quality standards. Features: Anti-Friction Washer - helps assure easy turning operation for the life of the hydrant. Oil Filler Plug - permits quick check of oil level. Lets you add oil without removing bonnet. Oil Reservoir O-Ring Seals - seal oil in, water out. Stainless Steel Safety Stem Coupling - pulls free if hydrant is hit by a vehicle preventing damage to the stem and main valve. Coupling will not break into pieces that could drop into lower barrel and affect valve operation. Top of lower stem is below the top of the lower barrel so that a tire cannot depress the stem and open the main valve. Repair is easy and economical. Safety Flange - breaks cleanly to help prevent barrel damage, yet is strong enough to withstand normal handling. Allows economical repair, adding of extension section, rotation or changing of upper barrel without digging or water shut-off. Bronze Upper Valve Plate - conical design for smooth flow. Drain Valve Facings - specially designed, long-life facings provide effective sealing. Ductile Iron Cap Nut - retains main valve. Seats against cap nut gasket to prevent corrosion of stem threads. Locked in place by a stainless steel lock washer. Mueller HP Epoxy coated for durability. 250 PSIG - 3-way hydrant:
250 psig (1723 kPa) maximum working pressure, 500 psig (3447 kPa) Shoe Designed For Maximum Flow And Easy Connection - with its smooth transitional contours, extended neck and integral anti-rotation pads, allowing use of standard tee-head bolts. The inside of the shoe is covered with MUELLER HP® Epoxy Coating. This thermosetting epoxy forms a tough corrosion-resistant barrier to chemicals, physical impact and electrical currents.
