All your videos are spot on. If people took the time to watch them before installing they’d never have to call you. I loved the user manual. The way my wife follows her recipe for cooking… that’s how I followed your user manual. I loved it. Every second of it. I’ve never had customer service like this.

RPS is now one of my very favorite companies.With the help of Daniel, I purchased a 6000watt Water Secure System. It was a great project to install and brought me back to using some skills that I haven’t used in years. It worked perfectly as soon as I turned it on.

- Susan, OK


We’re getting close to what, roughly five years but it’s working fine still.It’s been the best investment we’ve ever done, sir.Seriously. Oh yeah, the best thing we’ve done. We don’t have to run a generator, we’ve got plenty water, it’s always full, it always works and we can almost turn back on it.
