After seeing numerous recommendations for this controller, I installed the IRVWPC (Intelligent RV Water Pump Controller) today. This thing is fantastic.
It regulates the voltage to the pump which prevents hammering and offers supreme improvements in noise on lower flow.
I did a couple before/after decibel tests as well, it offered a drop of approximately 10dB (and no hammering if you use the toilet at night!)
I have posted the installation of this controller into my Minnie Winnie 22M: https://www.winnieowners.com/forums/...2m-364754.html
Many thanks to jwiebe for bringing this great water pump controller to my attention. I suspect others may wish to get one of these too. They really are great.
Thanks, Eagle5
