RO water pressure?

[Ramon Estevez]

If my RO/DI is running a little under 55 PSI do I need to buy a booster pump or should I look at it as a nice to have rather than a Need?

Nice to have, it will increase your efficiency of your RO membrane.

Can be quite a stark increase in the RO output by running your PSI in the 80's vs 50's. BRS did a good video on this, though be aware your TDS may slighly rise going into your DI resin.
