*all units that are in houses with low PSI haha there is the correction.
Lol, I just didn't want everyone reading this shopping for a new RODI system to think they HAD to get a booster pump as well. That's all, in MOST cases they are appropriate as it seems generally household PSI falls in the 40ish PSI Range. But it's not true everywhere, so it's always best to know the pressure of your home before investing in a booster pump
