Whats the pentair RO like? Good results?

What RO do you guys use? I'm looking to upgrade to a bigger system.

Ive had one for a couple of weeks 1st impressions are very good, produces at 60lph even at minimum tap pressure of 40psi but the product water does come out at 70ppm so resin use is high, i do now have a booster pump from Gardiners that im going to try next week to see if things improve further.

[Jakey boy]

70ppm seems high?

Can you give an update after you've fitted boosted pump?

I have the pentair prf RO. With a booster pump it is bringing tds down from 175 to 007. If your tap pressure is under 50 you will need a booster pump in the winter as its very slow without it.

Which booster pump are you using?

Would you mind posting a picture of your setup, showing the pump? I thought the pimp needed to be between the pre filters and RO membrane? But the prf doesn't seem to have a hose between the pre filters and ro membranes to attach the pump?

Ive set up my pump tonight on the pentair system it has improved it somewhat its now pumping at 65psi and the tds is now down to 40ppm i had expected more if im honest not sure if it will get better or if there is anything else that can be done to improve it.

Chris you need more pressure, get upto 80 psi and it will drop further.

How many ltrs have you run through it ?

Through the ro unit so far ive run through about 4000ltrs unpumped and about 500ltrs pumped how can i get more pressure the pump from Gardiners is only rated at 80 psi but its only running at 65psi

[Smudger]

I think it's down to supply, are you taking water from an out let near where the mains supply enters your house/property or further away like off a spur then through a hose?

You may find with the low pressure and small bore pipes and hose that Alex's pump is not suitable in giving you enough water and pressure.

I use this (4 yrs now)

If you ring them they will tell which is the best model I think mine is the 102 it pulls water through the pipe work giving you pressure and volume it was a lifesaver when home based as supply was around 15 psi

As said earlier, get extra prefilters because before you know it the membranes will be contaminated.

Which pre filters do you use Darran?

These housings

One sediment filter one carbon block - just standard the next filters will be fibre dyne ones also looking at the di vessel with acid cleaned charcoal that vin uses.
