I figured I would begin with the most recent upgrade I made to our RV (which is a Winnebago Travato Class B) I installed the IRVWPC2 Pump Controller more out of curiosity than necessity. We had so many people buying this upgrade I was really intrigued to see if it lived up to the hype. And I must say, if pump noise is an issue, this is your answer. It’s not a cheap answer but it will definitely quiet your water pump to a whisper. There is no pulsing, just smooth slow startup and shutdown. There are also a number of great safety features such as dry run protection, low flow protection, a running watchdog, and a long run timer to protect your pump from damage.
