Underwriters Laboratory (“UL”) and FM Approvals (“FM”), two third-party certification companies, have approved many of these products. Additionally, our products are typically specified by a water utility for use in its infrastructure system.

Water Flow Solutions

Water Flow Solutions’ product portfolio includes iron gate valves, specialty valves and service brass products. We recognized $824.9 million, $755.5 million and $634.4 million of net sales in our 2025, 2024 and 2023 fiscal years, respectively, for Water Flow Solutions products and solutions.

Water Valves and Related Products. Water Flow Solutions manufactures valves for water systems, including iron gate, butterfly, tapping, check, knife, plug, and ball valves, and sells these products under a variety of brand names, including Mueller®, Pratt®, and U.S. Pipe Valve and Hydrant. These valve products are used to control distribution and transmission of potable water and non-potable water. Water valve products typically range in size from ¾ inch to 36 inches in diameter. Water Flow Solutions also manufactures significantly larger valves as custom orders through some of its product lines. Most of these valves are used in water transmission or distribution, water treatment facilities or industrial applications.

Water Management Solutions

Water Management Solutions’ portfolio includes fire hydrants, repair and installation, natural gas, metering, leak detection and pressure management and control products and solutions. We recognized $604.8 million, $559.2 million and $641.3 million of net sales in our 2025, 2024 and 2023 fiscal years, respectively, for Water Management Solutions products and solutions.

Fire Hydrants. Water Management Solutions manufactures dry-barrel and wet-barrel fire hydrants. Water Management Solutions sells fire hydrants for new water infrastructure development, fire protection systems and water infrastructure repair and replacement projects.

Our fire hydrants consist of an upper barrel and nozzle section and a lower barrel and valve section that connect to a water main. In dry-barrel fire hydrants, the valve connecting the barrel of the hydrant to the water main is located below ground at or below the frost line, which keeps the upper barrel dry. Water Management Solutions sells dry-barrel fire hydrants under the Mueller and U.S. Pipe Valve and Hydrant brand names in the United States and under the Mueller and the Canada Valve™ brand names in Canada. Water Management Solutions also makes wet-barrel fire hydrants, where the valves are located in the hydrant nozzles and the barrel contains water at all times. Wet-barrel fire hydrants are made for warm weather climates, such as in California and Hawaii, and are sold under the Jones® brand name.

Most municipalities have approved a limited number of fire hydrant brands for installation as a result of their desire to use the same tools and operating instructions across their systems and to minimize spare part inventories. We believe the large installed base of Mueller fire hydrants throughout the United States and Canada, reputation for superior quality and performance as well as specified position have contributed to the leading market position of our fire hydrants. This large installed base also leads to recurring sales of replacement fire hydrants and hydrant parts.

Repair Products and Services. Water Management Solutions also sells pipe repair products, such as couplings, grips and clamps used to repair leaks, under the HYMAX®, Mueller® and Krausz® brand names.

Natural Gas Distribution Products. Water Management Solutions produces machines and tools for tapping, drilling, extracting, installing and line stopping, which are designed to work with its water and gas fittings and valves as an integrated system. We also provide gas valve products primarily for use in gas distribution systems.

Water Leak Detection and Pipe Condition Assessment Products and Services. Water Management Solutions develops technologies and offers products and services under the Echologics® brand name that can non-invasively (i.e., without disrupting service or introducing a foreign object into the water system) detect underground leaks and assess the condition of water mains comprised of a variety of materials. We leverage our proprietary acoustic technology to offer leak detection and condition assessment surveys. We also offer fixed leak detection systems that allow customers to continuously monitor and detect leaks on water distribution and transmission mains. We believe Water Management Solutions’ ability to offer non-invasive leak detection and pipe condition assessment services is a key competitive advantage. With our Singer Valve and i2O products, we provide a range of intelligent water solutions including pressure control valves, advanced pressure management, network analytics, event management and data logging.

Water Metering Products and Systems. Water Management Solutions manufactures and sources a variety of water technology products under the Mueller® brand name that are designed to help water providers accurately measure and control water usage. Water Management Solutions offers residential, fire protection and commercial metering solutions. Residential and commercial water meters are generally classified as either manually read meters or remotely read meters via radio technology. A manually read meter consists of a water meter and a register that gives a visual meter reading display. Meters equipped with radio transmitters (endpoints) use encoder registers to convert the measurement data from the meter (mechanical or static) into an encrypted digital format which is then transmitted via radio frequency to a receiver that collects and formats the data appropriately for water utility billing systems. These remotely or electronically read systems are either automatic meter reading (“AMR”) systems or fixed network advanced metering infrastructure (“AMI”) systems. With an AMR system, utility personnel with mobile equipment, including a radio receiver, computer and reading software, collect the data from utilities’ meters. With an AMI system, a network of permanent data collectors or gateway receivers that are always active or listening for the radio transmission from the utilities’ meters gathers the data. Water Management Solutions sells both AMR and AMI systems and related products. Our remote disconnect water meter enables the water flow to be stopped and started remotely via a handheld device or from a central operating facility.

Manufacturing

See “Item 2. PROPERTIES” for a description of our principal manufacturing facilities.

We will continue to expand the use of Lean manufacturing and Six Sigma business process improvement methodologies where appropriate to safely capture higher levels of quality, service and operational efficiency in our manufacturing facilities in both segments.

Mueller Water Products operates ten manufacturing facilities located in the United States, Israel and China. These manufacturing operations include foundry, machining, fabrication, assembly, testing and painting operations. Not all facilities perform each of these operations. Our existing manufacturing capacity is sufficient for anticipated near-term requirements. Our new brass foundry in Decatur, Illinois, is operational, and we have closed our legacy brass foundry that was built in the 1900s. Our iron foundries use both lost foam and green sand-casting techniques. We use the lost foam technique for fire hydrant production in our Albertville, Alabama, facility and for iron gate valve production in our Chattanooga, Tennessee, facility. The lost foam technique has several advantages, especially for high-volume, larger products, including a reduction in the number of manual finishing operations, lower scrap rates and the ability to reuse some of the materials while the green sand process is better suited for smaller, simpler parts. Over the next few years, we intend to increase capital investments in our facilities to expand production capacity and enhance operational capabilities, including investment in our two iron foundries.

Additionally, we design, manufacture and assemble water metering products in Cleveland, North Carolina. In Atlanta, Georgia, we design and support AMR and AMI systems in our research and development center of excellence for software and electronics. Our facility in Jingmen, China, manufactures and assembles specialty valve products, and our facility in Ariel, Israel, designs, manufactures, and assembles repair products and solutions. Our research and development center in Toronto, Ontario, Canada, designs and supports leak detection and pipe condition assessment products and solutions. Product design and support for our intelligent water solutions products and services for pressure management are in Southampton, United Kingdom.

Purchased Components and Raw Materials

Our products are made using various purchased components and several basic raw materials that include brass ingot, scrap steel, sand and resin. Purchased parts and raw materials represented approximately 35% and 8%, respectively, of Cost of sales in 2025.

Patents, Licenses and Trademarks

We have active patents relating to the design of our products and trademarks for our brands and products. We have filed, and continue to file when appropriate, patent applications used in connection with our business and products. Many of the patents for technology underlying the majority of our products have been in the public domain for many years, and we do not believe third-party patents individually or in the aggregate are material to our business. However, we consider our proprietary information consisting of expertise and trade secrets relating to the design, manufacture and operation of our products to be particularly important and valuable. We generally own the rights to the products that we manufacture and sell, and we are not dependent in any material way upon any third-party license or franchise to operate. See “
