I have just installed a booster pump on my RO, and I am not sure what is doing, my flow rate or water prodution has not increased at all.

When i first installed the  pump it ran for 30 secs, then ran again 20 mins later for another 30 secs, is this right, the reading on the pressure dial is 2.5 bar, is that about right ?

Just been in the garage for 30 mins and the pump did not kick in once, even though i produced a litbout 50 litres  in that time, i cant undertand if i am producing water why the pump does not kick in more than it does.

Cheers for any help

open your flush value/tap right up,it cause of the back presure that the pump is not running,when it starts runing then start closing the value back a little.

We've just recently discussed pumps, boosters in particular here................

Have a quick check of it. 2.5 bar is roughly 40 odd PSI. You don;t say what type of booster pump you have but there should be a screw on the side of the electrical box which allows you to turn up the PSI.  Yours sounds like its set to 2.5 bar, you wanna turn the screw and set it for maybe 4.5/5 bar thats if it will go that high.

Dave, I think you made the same mistake as we did when we first bought a booster pump.

I think the pump you've got is an "on demand" pump which will kick in when pressure drops below a certain psi ..ie when another tap on system(kitchen) is opened, it senses a drop and will start up. They are not designed to run continuously.

We took ours back and exchanged it for a "continuous" use one like this..

I think it is this one, but is certainly the same shape and type

It is an on demand pump maybe I should use this one on the house and buy another, but probs a bit noisy for that.

There is no pressure adjust screw as it is factory preset and cannot be adjusted

Frank I tried flushing on full speed and was just the same

I had this as well so my guess would be to do what FPB suggests

Yep thats the pump we bought first Dave. All it will do is kick in when mains pressure drops below 2.5 bar

Hi will this pump work if there is a float switch on my tank.will it turn off when the tanks full or u gotta watch tank.

[Ian Lancaster]

Hi Dave,

I presume you are running a 40-40?

you need this pump:  http://www.machinemart.co.uk/shop/product/details/cbm240e-1in-multi-stage-230v-booster-pum We've had one running on our 40-40 for a couple of years now.  Runs at about 75-80psi and has a built in non-return valve.

Cliff,

Without looking, this subject was discussed a while back. If your float switch will handle more than 5 amps then you should wire it into that along with a solenoid valve. They must operate (switch on) together.
