PSI for RODI

[dottybacks]

Hi I am new to this fourm and I am from Canada I have been into the hobby for over two years now. I have a question about my rodi system that purchase from aquasafecanada yesterday. Theminimum operating water pressure is 50 PSI but the water pressure in my house is 40-60PSI because I am living in a condo so is this going work and how do I notice that if the PSI is lower than 50?

It will be fine. 40 psi is about the minimum operating pressure they will work efficiently at with 60-80 being preferred as it makes the membrane more efficient.
Something you might try is to watch your pressure throughout the day and on different days of the week to see when it is highest and make water during those periods to increase the life of your DI resin.

Hopefully you bought a handheld TDS meter too so you can monitor the membrane and DI conditions. You will notice when pressures are higher the TDS coming from the RO membrane will be lower and it will increase slightly as the pressure goes down and the membrane is less efficient. The lower the RO only TDS the longer your DI will last.

Yes I do have a TDS meter it comes with the purchase. Thank you for the info it helps a lot. Well I am still wondering hiw to put all the parts together it kind of confuse when I look at the instruction on their website.
