    4040 RO Booster Pump

    I've had my 4040 RO for 12 months now. Got it from Doug at Daqua who I can't rate highly enough. I've always been good at changing my filters as per the recommendations, flushing regularly etc etc. The unit is kept away from frost and I like to think well looked after. The issue I always had was it was running at 40psi and would only ever give a 91-92% rejection rate. After much deliberation I decided to invest in a booster pump. Bought from X-Line and double checked it would be sent wired and ready to go. It arrived all ready and I can't rate it highly enough. I'm now getting between 70-90psi and a 96% rejection rate so the pump will pay for itself. Link and pictures below incase it's useful to anyone else in the future. Thanks @spruce and @Tuffers for your help with this. https://www.xline-systems.co.uk/en/xline-shop-2/wfp-controllers-pumps/240v-booster-pump-with-electronic-shutoff-detail

    RO booster pump advice

    I bought a 4040 RO with a HF5 membrane a few months back. My tap pressure reads approx 50psi. The RO is in the garage at the front of my house and the tap is at the back. I’ve run 15 meters of hose to the RO. Originally I had a hose reel and couldn’t get past 35PSI, once the reel was removed the actual hose gives me just over 40 PSI. This is measuring just after the prefilters and before the membrane. Once I set it to 55/45 I’m running anywhere between 30 & 35 PSI. when I bought it I had a TDS of 175-210 and got an output of 9-12. This rose over the summer & fluctuated between 210 & 420. This wasn’t too bad as I would just wait for the TDS to drop back to 210 and get 12 out but recently it’s been consistently between 350 and 410 and I’m struggling to get below 30 output. I’ve checked and tested every part of the RO and been on the phone to Doug at Daqua and I’m confident it’s all set up well. I am assuming I’m getting such a shocking output because I’m running at 30-35PSI. im considering buying a booster pump, I reckon this will pay for itself in the resin saved. Does anyone have any other suggestions and can anyone recommend a good pump. I currently use a solenoid shut off, will this work with a booster pump?
  3. Just bought a booster pump and it says on the pump "inlet pressure: 30psi" Does that mean it requires an inlet pressure of 30psi or that 30psi is the maximum. Anyone know?
