This review of All Pro Water Flow originally appeared in the October 2003 issue of RV NEWS.

Preston Hall, the inventor of the All Pro Water-Flow system, has been an RVer for years. And just like other RV owners, he’s had to deal with holding tank odors and false readings from tank monitor.

A lot of conditions contribute to odor problems in black and grey water tanks — among them is the content that is not eliminated when dumping, sludge and paper hanging up on sensors, and by mixing different chemicals.

Even using existing cleaning attachments, which are usually attached to garden hoses, it’s extremely difficult to eliminate build-up in holding tanks. These attachments operate at between 40 and 50 PSI, and just can’t get rid of all foreign matter.

The All Pro Water Flow system is based on thoroughly hydro-jetting the RV’s tanks. At pressures between 1,750 and 6,000 PSI, depending on the size of the holding tank, and using clean water, any tank will be completely cleaned and flushed. Custom adapters and nozzles determine the spray pattern, and with the use of clear pipe connectors along with a fiber optic camera, your customers can watch the cleanup take place. A complete holding tank service takes just about one hour, and your customers won’t even have to leave their rig when it’s being done.

The All Pro Water Flow system works equally well on boats, buses, and airplanes. The operation can be done at your lot, at a campground or other location — generating new revenue stream for your company.

Many RV dealers have been referring their customers to All Pro Water Flow, and K&C RV, the largest RV dealer in Colorado, is the newest dealer to take advantage of an All Pro Water Flow service center.
