We’re RVers just like you

and we know how you feel about your holding tanks!

We’re Lee and Sheila Harris and we started RVing in 2016 when we were getting ready for retirement and wanted to travel. The RV life just seemed “right” for us and we made the investment, like many RVers do.

And as everyone with an RV knows, you always seem to have problems with your black and grey tanks. We were frustrated like a lot of other RVers. We found Preston Hall and the All Pro Water Flow company. Everyone told us to get a pump truck but but Hall told us we just needed the right person — and the righ service — to clean our RV’s tanks. We were happy with the service — and results — and quickly joined the All Pro Water Flow family, helping other RVers with their tank problems.

Whether you’re full-time like us or just vacationing, you know how disturbing it can be to have a problem with your RV’s holding tanks. Ours were stinky and the tank sensors hadn’t worked in years!

In our search for a solution, we met Preston Hall, the inventor of the All Pro Water Flow process, and had our RV’s holding tanks professionally cleaned. Boy, were we amazed at what had been building up for years and years and years!

Preston took the time to tell us how waste can build up over time, affecting the sensors, and causing other problems. He explained how important it is to keep the tanks filled with liquid, how often to flush them, and even how chemicals can cause tanks to gum up and become clogged. One tank cleaning procedure and we were sold!

Now, we’ve become an authorized All Pro Water Flow dealer — and hope to educate other RVers on proper holding tank maintenance and care.

We can’t emphasize that last point enough — even though you may not think you have problems now, it’s important to have your holding tanks professionally flushed and cleaned at least once a year.

Reach out to us and we’ll explain more and we’ll give you a FREE estimate on cleaning your black and gray holding tanks as well as your water heater tank.

Our service is the only way you will get your RV’s waste tank sensors working properly again. Thanks and see you out there!
