This video shows the installation of the Intelligent RV Water Pump Controller manufactured in Canada by Sylva Control Systems, Inc. I first learned about this device from the "All About RVs" YouTube channel in this video:

Claimed advantages of this controller include:
* Modulates pump speed to smoothly & quietly deliver just the needed water amount
* Longer pump life
* Less power consumption
* Configurable safety features: dry run protection, low flow protection & watchdog timers

The IRVWPC can be purchased directly from the manufacturer here. Their website also includes several excellent installation & setup videos:

At the time this video was created (May 2023), the IRVWPC cost $229 Canadian (approx $169 US).
