Tucker RO/DI and water pressure question

Am I missing something, is their a way to turn up/turn down the water pressure on a tucker ro/di, or do I need to buy some sort of attachment?
Thanks for any input!

A pump…

Do you feel as though you are not getting enough pressure?

If you’re coming from using a DI tank or a DI only system, moving to an RO/DI system can be a bit of a shock as the output is about 1/2 of what you’re used to, still enough to clean glass but no more. The only way to increase the flow rate is to add a pump.
