My RO system is a Watts Premier RO Pure and I want to make sure my DI filter is in the correct spot. I’ve had it in position A as noted below as the final stage before going into a pressurized tank. But the more I’m thinking about it, the way my system works would have the water pass through the DI filter and enter the tank but then when it runs to the faucet, it passes in reverse mode through the DI again and this doesn't seem correct. My other option is to put it in position B after the pressurized tank but from what I have read this shouldn't be done because of the high pressure that would be pushing water through the DI filter. One other option I have considered is putting it in position A but have a valve to bypass the DI when it runs to the faucet.
I would appreciate any advice.
Thank you.
