At what water pressure level do I need to add a booster pump?
Read online that increasing the pressure to 75 -85 psi drops the TDS resulting in less use of DI resin.
Any opinions
I'm not willing to risk my tank on an ebay system prefer name brands, if ebay has it for $100 and most others are $200-$225 something has to be different.
I have thousands of $$ in the tank plus my time
the Spectrapure is worth a look
