Ive got really low water presure at the moment would a pump help? i've seen one on gardiners @ £150 + to run all the time do you think this would be a good thing to run all the time? i had low presure b4 but this is just silly

how low is your pressure?  i keep getting told mine is rubbish at 43psi. My RO still works though.

The trick here is to get the right pressure for the system if you want optimum performance.
Yes a system will stil produce at a lower pressure but the amount of waste to product will increase or in other words it will take longer to produce the amount of water compared to a higher pressure.
Not sure of the price but RO Man supply booster pumps.

pressure is important, but without a high enough flow rate you could have 100psi and production still wouldn't be up.  Whatever pump you go for make sure it has a high enough flow rate to meet your pumps demands - normally 4 times the maximum output.

I'VE GOT ABOUT 15 PSI at the moment

15 psi you definately need a pump it must be just dripping out with pressure that low.
I have 55psi water pressure but bought a booster pump with my system and it has made a big differance in the amount of water it makes

Are you sure you have it connected to a mains supply and not your water tank in the attic.

yeah i;m sure  lol, it was 35 but it has dropped dramaticly in the past month. Where did you get your pump from? can you recommened.

[neil100]

I,m in the same boat. I was just going to start a new topic on the subject but Mr Bond beat me to it.

I think my water pressure as droped. I have a Low pressure membrane, a 40 40 RO. My tds going in is 100 and its comeing out at 13. Though I am probably producing 1ltr of pure water to 3 ltrs of waste. I could adjust the valve and produce the pure water a bit faster but my tds would be around 20.

Like Mr bond I have seen the b 70 LPM Booster Pump on Gardiners site, Heres their explanation of it.

To be used if your mains water pressure is too low for an RO system to work. We recommend this for use with a Merlin RO unit in areas with water pressure below 60psi. This will increase production rate (up to 225 litres per hour), lower water ratio and decrease TDS output (down to 001ppm depending on input quality). Most other 'booster' pumps for RO systems are not designed for use hour after hour and will burn out if used for anything other than occasional use. This booster pump is man enough to cope with the demands of a Merlin on full demand.

I had my pressure tested before I bought my Ro nearly a year ago. It was 45psi, I think its lower now. Would that booster pump make a diffrence?

Would that Booster Pump damage my Low pressure membrane?

If I bought it what would my tds be approxiamtley?

Its the same price as a couple of bags of resin so I have to work out if its worth my while buying it.

I bought a pumped R/O unit from the R/O man.
So could not say how much they are as mine was in with the price.

Hi Neil100

The booster pump should make a big difference to your ro.  Firstly, 13ppm from any RO is unacceptable, it should be lower - a lot lower.  We use a merlin and get get product water of 5ppm from an inlet of 300-350ppm.  By increasing pressure thre tds readings should drop to somewhere around the 4/5ppm.  Secondly, you haven't mentioned rate of production but I would hazard a guess that its lower than it should be - again a booster pump will improve production.

Before you buy any booster pump though - check your sediment and carbon filters are in good condition.  Replace if necessary.

Lastly, give Steve at Freshwater systems a call - he may be able to help out with a booster pump for you.
