Hello all. I need your help in convincing some of my customers that they have a less than optimum RO delivery system. What pressure do most of you use to deliver this? I keep running across a lot of places that use a basic irrigation pump, with a bladder tank setup. When new something like this will deliver water at around 50 psi. I like to use a booster pump that puts it out at a little over 200 psi. I think a lot of distributors use these cheap pumps because they are cheap and simply don't know any better. So that I don't come across as simply trying to sell these people something they don't need, I thought it a good idea if we could see what the norm is.

Spot free rinse pressure to bays ?

Ours comes out at a higher pressure than most, about 350-400 psi. We have found that customer like this better. It feels like there getting something, but its not too much that they can use it instead of high pressure rinse. I think that water usage is about 2 gpm at this pressure

At one location it comes out at 200 psi and at another we have it at 500 psi coming out of the hp. pump. People love it that high. I also agree that you don't want to go to high cause people would use it for hp rinse. I think alot of this should be based off of what you can produce in your ro unit.

We're also running medium (450 psi) pressure with a Cat 390 pump and large orifice solenoids. There are a few customers who use it instead of rinsing, but it's infrequent and easy to convince them that it's cheaper to go around once with high-pressure rinse before spot-free. At least 80% end the cycle on spot free rinse.

250 psi, procon pump.
In my case my distributor used a shallow well jet pump on a precharged bladder tank that only put out 40-60 psi. I think the main reason was it was easier to install and charged about as much as a booster pump. I changed it to 350 psi and use of SFR went through the roof. With my old system almost no one used it.

I run about 200psi also.
I realize this is old but what kind of tubing to you use for this pressure? My tubing is 3/8 od white unmarked tubing that runs out to each bay. We currently have 125 psi and I am wanting more.
