Wachs Hydro-Vac Trailer is a safe, non-destructive and cost-effective machine for precise utility excavation that requires less backfill and restoration. The Hydro-Vac trailer prevents underground damage, while offering a more accurate way to excavate soil and locate underground utilities. Powered by a long lasting Kubota 4 stoke diesel, the trailer comes with a Pintle hook for connection to a medium duty pickup or larger truck.

Built off Wachs Standard Builder Trailer platform, it can be configured just the way you want it, built exactly to fit your needs and budget. Its future upgrade path means you can order what you need today, knowing that you can upgrade the trailer tomorrow. The Standard Builder allows for an ala carte selection of our standard valve maintenance modules to be installed onto our heavy duty trailer. The Builder platform’s upgrade path offers maximum versatility – for example, configure a Hydro-Vac trailer with hydraulics today, add a ERV-750 Valve Exerciser later.

A step up in power, capacity and size from the smaller Trav-L-Vac 300, the Hydro-Vac trailer includes a powerful vacuum that generates 500 CFM at 11in Hg. It includes a large, 250 gallon spoils tank that features our exclusive hydraulic powered slide, tilt, and dump system with power latching door, here in a rear dump configuration.  This power spoils tank features a twin cylinder, electric over hydraulic dump system that incorporates a slide and tilt system that moves the tank out before tilting to clear for dumping, then lifts to 55 degrees to discharge debris.

Also driven from the common power train is a 2.5 gpm @ 3000 psi pressure washer system with 3 gallon anti-freeze tank and 95 gallon vertical water tank. Includes 2-1/2in, 1-1/4in & 7/8” suction wands, short & long wash-down guns, 20ft suction hose and 50ft retractable hose reel.

Note a valve exerciser is not included with the Hydro-Vac trailer, it features vacuum, power spoils tank and power wash units only. Valve exercisers can be ordered separately, or refer to our diesel powered Standard LX Trailer that includes the ERV-750 exerciser for fuller valve maintenance capabilities.
