Valve Maintenance Truck Package


Knapheide Custom Service Body with Integrated Wachs Valve Maintenance Skid

Wachs has partnered with Knapheide to create the most efficient and complete valve maintenance truck, equipped with maximum storage and delivering unparalleled power and versatility.

To begin, order your chassis cab fleet vehicle from your preferred dealer to meet all applicable federal, state and local regulations. Wachs Utility Products has no involvement with the truck chassis cab itself, beyond ordering recommendations and specifications. Wachs strongly recommends custom ordering your vehicle to ensure it meets these minimum required specifications:

  1. Minimum rating of 19,500 GVRW
  2. Cab to axle length of 84 inches (213.4 cm)
  3. OEM high output 300 amp or dual alternator arrangement (to supply the custom service body's 200 amp power inverter load, plus the truck's electrical load)
  4. OEM upfitter switches
  5. OEM rearview camera and prep kit
  6. OEM backup alarm

Drop ship your truck chassis cab to Knapheide using site codes: Chevy 132052, Ford 88QNR4, Ram T8569. Upon delivery of your vehicle Knapheide will upfit the custom service body onto your chassis cab. They will then install Wachs Service Body Skid, available with diesel or gasoline power (tied to the vehicle's engine type) to the custom service body, complete with all mechanical, fluid and electrical connections, ready for pickup. 

Choose from the options that best fit your needs. Wachs Service Body Skid, combined with Knapheide's customized service body professionally upfitted, creates the industry's most advanced valve maintenance truck. You specify and order your truck chassis cab, have it delivered direct to Knapheide and we do the rest. Note the service body and upfitting is unique to each truck brand and engine type.

Service Body Valve Maintenance Skid

Wachs Service Body Skid is used in conjunction with the custom Knapheide service body.  Assembled by Wachs and shipped direct to Knapheide, it is upfitted following installation of the custom service body to your furnished chassis cab.

The Service Body Skid is available with diesel or gasoline power, tied to the choice of engine in the chassis cab. It draws its fuel supply from the truck, eliminating the need for separate fueling of the SB Skid’s diesel or gasoline engine. Like our other skid platforms, all Wachs valve maintenance components such as the vac system, water supply, spoils tank and HPU come preinstalled and prewired to a steel skid, ready to bolt down to the custom service body, complete with all mechanical, fluid and electrical connections to the truck chassis cab.

The Service Body SB Skid can be optioned with a wide range of valve exercising machines, vacuum systems with powered spoils tanks, hot water systems and more. Typical equipment includes a powerful 500 CFM-11in Hg vacuum, a 250 gal spoils tank utilizing Wachs exclusive hydraulic slide, tilt & rear discharge, with a power latching rear door. Also standard is a 2.5 GPM@3000 psi pressure washer system and 80 gallon water tank, with an optional hot water system for colder climes.

A HPU (Hydraulic Power Unit) with a HTMA Class II circuit is included, with a 10 gal reservoir, and a fan cooled heat exchanger, producing up to 8 gpm @ 2000 psi to operate the ERV-750, optional TM-7 HD Plus, and accessory hand tools such as breakers. A 50 foot hydraulic hose reel, programmable arrow board and work lights round out the equipment list of this utility workhorse.
