RO/DI on Low Pressure

[sparks]

I currently use a TWP (Tap Water Purifier) for my make up water.
I would like to go to a RO/DI system but as i am on tank water only, i have a house hold pressure pump. Is there anyone using a RO/DI on a house hold pressure pump say of 30/35 PSI Max.
If so what brand. Is their any problems with its operation?

You'll need a booster pump. You can get them on line. for 120-150$ I use one from Premier Water System it was the best price I could find and easy to install

I use my reefpure RO/DI on my standard household pressure. It will work. You just wont get the rated output. I get about 25 GPD. I use the tornado model.

You do need a booster pump. With low pressure not only do you get less output, but the output from the RO membrane is of much lower quality too. Without a pump you will exhaust you DI resin far too quickly - this may not be a cost-effective scenario long-term.

Thanks for that guys.
I have read that a few reefers using the TWP have reported unacceptable readings of phosphate from them.
I must say if the cartridge is replaced before its spent, i have always had Phosphate readings of zero. Any comments on TWP please?

They work 100% fine.
