RO/DI and water quality questions

Minimum pressure is like 40, but that will not be good on your membrane. I ended up buying a booster pump and chloramine kit and I'm not looking back. Yes it's a little more, but at least I know I'm covered if the city decides to do something and put more chemicals in the water.

Will this work?

So what do you think Matt? I have 80psi when the water hits the membrane or that's what it reads on the gauge. Overkill for a 75gpd membrane?

80psi is a little high and should be ok without a booster pump for sure

I have a booster pump on it, the gauge prior to membrane is reading 80psi. Getting 0 to 1 TDS before DI. Overkill or not, I'm fine with it and nobody is complaining.

Checked my pressure before the rodi unit. 53psi. Is this ok or do i need a booster pump?
