I've never had any luck with red hat (reach to wash?) either stuff didn't do what was stated (RO unit) or arrived broken (filters)
I know they use pro pumps and I've used these but they only lasted 5 months the supplier ( not red hat ) did replace them but this was only 3 months ago so these are still running and time will tell if they last
Nice guy but gets a bit uptight when dealing with problems
