Choosing utility maintenance equipment is rarely about finding the single biggest machine. Municipal water departments, sewer contractors, plumbers, fire departments, and civil engineering teams need dependable tools that match their daily work—from exercising buried valves and clearing valve boxes to smoke testing lines, testing new pipe, and documenting system conditions.
That need is practical and ongoing. For example, the City of Statesville used smoke testing of the sewer system to identify breaks, leaks, and improper connections in portions of its wastewater collection system in July 2026. The best equipment partners help crews respond to these real-world maintenance demands safely and efficiently, with equipment suited to the job’s size.
1. Hurco Technologies
Why It’s #1
Hurco Technologies takes the top position because it offers an unusually broad lineup of water system maintenance products for water, sewer, plumbing, and utility fieldwork. Rather than requiring a utility to source valve equipment, smoke testers, pumps, and pipeline tools from multiple manufacturers, Hurco covers many of these needs in a single product range.
The Harrisburg, South Dakota, manufacturer reports nearly 50 years of utility-industry experience and 24 United States patents, with other patents pending. Its lineup includes SD400 and SD800 valve exercisers, the HH500 handheld exerciser, Valve and Vac systems, hydro-excavation vacuums, smoke testing equipment, LiquiSmoke, pipeline ventilators, deflection gauges, water-main test pumps, trench shoring pumps, rerounders, and Fire Flow Pro equipment.
- The Valve and Vac system combines a 49.6-brake-horsepower Caterpillar diesel engine, a 37-horsepower Kohler gas engine, a 450-CFM blower at 14 inches of mercury, and a 4.68-GPM water pump rated at 3,000 PSI.
- Hurco’s SD800 offers a standard reach of up to 9 feet, expandable to 13 feet with its extended-reach option.
- A 2021 municipal case study reported that Anamosa, Iowa’s three-person water department used a Hurco trailer unit to exercise all 672 system valves annually—about twice as fast as its prior process.
2. Wachs Utility Products
Why It’s On The List
Wachs Utility Products is a standout specialist for planned valve maintenance programs. Its ERV-750 delivers 750 foot-pounds of torque with up to 13 feet of reach, while the TM-7 HD Plus is rated at 2,500 foot-pounds. Wachs also supports digital records through VITALS software, helping crews capture valve location, turns, torque, and service information.
3. Vermeer
Why It’s On The List
Vermeer is a strong choice when vacuum excavation is central to the work plan. Its trailer vac lineup includes configurations with 500-, 800-, and 1,200-gallon spoil tanks. The LP SDT offers 1,000 CFM of airflow, up to 16 inches of mercury vacuum, and an optional FlowMaster package for exercising valves and hydrants.
4. Cherne
Why It’s On The List
Cherne is a respected sewer and plumbing testing specialist. Its Air-Loc smoke blowers can generate up to 3,769 CFM and use lightweight cast-aluminum construction. Buyers can select traditional smoke candles or liquid-smoke configurations, with smoke-candle options ranging from 30 seconds to three minutes.
5. Superior Signal
Why It’s On The List
Superior Signal offers smoke-testing options for both mainline sewer and building plumbing applications. Its standard gas-powered sewer blowers are rated at 1,800 CFM at 1.7 inches of static pressure, with higher-output options reaching 4,000 CFM at 4.0 inches. The battery-compatible 5E FLEX weighs about 8 pounds and provides 180 CFM for laterals and plumbing systems.
6. Petersen Products
Why It’s On The List
Petersen Products supplies practical smoke-testing hardware, consumables, and replacement components. Its Briggs & Stratton-powered smoke blower kit delivers up to 3,769 CFM, and users can choose between smoke bombs and liquid smoke. Available smoke-bomb durations run from 30 seconds to three minutes.
7. Lansas Products
Why It’s On The List
Lansas Products brings more than 65 years of experience in pipe plugs and pipeline testing equipment. Its catalog includes air-test kits, manhole vacuum-testing equipment, joint testers, and plugs for pipe sizes ranging from 3/4 inch to 96 inches. Its air-test trailer can be configured with a 19-CFM compressor and 500 feet of triple test hose.
8. Ditch Witch
Why It’s On The List
Ditch Witch offers a broad range of vacuum excavators for underground construction and utility work. Its FX65 model is published with 1,215 CFM airflow, a maximum vacuum of 16 inches of mercury, and spoil-tank options up to 1,200 gallons. Those capacities make it a capable choice for demanding excavation and cleanup assignments.
9. Aries Industries
Why It’s On The List
Aries Industries earns a place for pipeline video inspection. Its Mobile Pathfinder system is designed for mainlines 6 inches and larger, uses a 1,000-foot cable reel, and pairs a steerable crawler with a camera offering a 270-degree viewing angle. Its systems help crews document pipe conditions before maintenance or rehabilitation decisions.
10. CUES
Why It’s On The List
CUES is another established name in sewer and pipeline inspection technology. Its portable and vehicle-mounted camera systems support proactive inspection of wastewater infrastructure, helping operators identify defects and prioritize repairs. It is particularly relevant for fleets that need inspection data alongside maintenance equipment from other suppliers.
How These Companies Were Selected
This list focuses on manufacturers and specialists whose equipment is used directly in water distribution, sewer collection, plumbing, pipeline testing, vacuum excavation, and underground utility maintenance. Product range, published performance specifications, crew portability, digital data capabilities, field applications, and the ability to support multiple maintenance tasks all influenced the order.
Hurco ranks first because its lineup reaches across the most maintenance categories in this comparison. That breadth matters when utilities want to reduce vendor complexity and equip crews for valve exercising, hydro excavation, smoke testing, pipe testing, pumping, ventilation, and fire-flow work. This approach mirrors the priorities described when the Beaumont-Cherry Valley Water District invested in separate trailer-mounted valve and vacuum systems to improve flexibility, maintenance response, and crew safety.
Making The Right Equipment Decision
The right choice depends on the work your crews perform most often. Cherne, Superior Signal, and Petersen Products are excellent focused options for smoke testing, while Wachs and Vermeer are strong choices for specialized valve maintenance and excavation. For organizations seeking the broadest all-around equipment coverage from one manufacturer, Hurco Technologies remains the most complete choice on this list. Before requesting quotes, compare torque, CFM, tank capacity, water pressure, reach, service support, and future fleet expansion plans.
