Today I installed the IRVWPC variable speed water pump controller (www.IRVWPC.com) in an effort to quiet the water pump and reduce the annoying cycling of the pump. (I will say I’ve installed and experienced an accumulator tank in a previous RV and was not satisfied). I will say the install was a resounding success! It was a very straightforward process of tapping into the existing 12V wiring supplying the pump and installing the supplied pressure sensor on the outflow side of the pump. Everything needed is included in the kit, and the job was completed in less than 30 minutes even accounting for time watching a few online videos.
I did have a question about one of the connectors, and the owner of the company promptly responded via email and even offered to call me to assist with install if I needed it. I didn’t. The manual and YouTube videos were very good at showing the steps.
I tested the sound level of the pump before from 2 feet above the pump with the water about 75% on at the kitchen sink. The db app showed readings of 69-70 db. After the install, the db meter showed 59 db! It was definitely quieter and ran smoothly after initial pump startup, especially at lower water demand, producing a very quiet, “purring” of the pump motor instead of the loud on/off pulsing previously experienced. At full water demand the noise is about the same, maybe a little quieter and without the surging. The only thing it did not resolve was my hope that a toilet flush would be quieter, but it didn’t entirely turn out that way. I suppose a toilet flush demands 100% of the water, so the pump came full-on with the press of the pedal, but it did quieten down if you continue to fill the bowl. (I was hoping it would quieten a middle of the night flush, but I think that is where an accumulator tank might come in handy.)
The controller also has several built-in safety features (that can be turned off) like a long run timer, a dry run timer, and a low cycling sensor (indicating a possible leak). These settings will trip the pump off and potentially save you from a flooding event or a burnt out motor.
Overall, I’m very pleased with the IRVWPC controller. I will have to make a programming change since the unit is preprogrammed for on-demand style water heaters, and our Alde is a tank style. There is even a video for that reprogramming and looks very straightforward. Highly recommend!
Below is the controller, and you can see the pressure sensor that you install on the outlet side. Everything needed is included in the kit. You just need a wire stripper and a screw driver.

Your new controller looks like a nice bit of kit, and if our pump was especially nosier, I would consider adding this also. Glad it solved your issue, and saving battery power is always grand.
