Big VacuFlush Power for Small Boats


For performance boats and other trailerable boats with space too limited for typical marine toilet systems, VacuFlush VHT vacuum holding tank systems make it easy to install a complete VacuFlush toilet system on boats from 19 ft. (5.8 m) in length.

VHT models integrate a vacuum pump, vacuum reservoir, and waste holding tank into one easy-to-install unit.

Compact in size, VHT units deliver all the benefits of larger VacuFlush systems, providing a waste tank with as much flush capacity as holding tanks that are sized for much larger boats.

Key Benefits

  • 9-gal. (36-l) waste capacity; holds as many flushes as 30-gal. (114 l) tank with standard marine toilet
  • 3/4- and full-tank sensors
  • 12 V DC operation
  • Swivel discharge fitting
  • Compact units combine vacuum pump, vacuum reservoir, and holding tank
  • Corrosion-proof, leak-proof, odor-proof
  • Easy to install - no solvent bond connections needed
  • Auto "full tank" shutdown prevents tank overfill
  • Optimized for use with versatile VacuFlush 5140 series toilets
  • High-density polyethylene tank construction
