  1. 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?
  2. Hey guys this is my first post, been lurking around for a year and found some good information that's helped me so thanks to the community, I wouldn't be where I am without you. I've took some readings of water pressure from my wfp system and wanted to know what membrane and booster pump I should purchase that fits my needs. I'm not sure my current setup is efficient as I bought the system from my brother without doing any research. The system was professionally installed by window cleaning warehouse (phoenix system). I want to make sure it's right as I realize having the wrong membrane or low water pressure is sub optimal in the long run and also these membranes aren't cheap! My brother with the same system is replacing his every 6 months so obviously isn't right. My questions are: What membrane would you recommend I buy? What booster pump should I buy? Outside tap pressure: 45 PSI (3.1 BAR) Outside tap water flow rate: 25L per minute (1500LPH) So from what I've read most people have a HF4 or HF5 4040 membrane which is what I have now, which requires 80-100PSI to run efficiently so I know now I should use a booster pump to raise my water pressure. I don't know though which one is suitable for my water pressure and flow rate of my outside tap to pump enough water to feed the membrane. I have 2 pre filters before the membrane (sediment and carbon filter) Water pressure after pre filters before membrane input: 30PSI (2BAR) I would like to continue to fill my 500L tank up in 4-5 hours like I do already with my setup. Thanks for reading, can't wait to get some help been sat here for hours researching!
  3. I've just moved house but before I moved I thought I needed new RO membranes as I was only getting 12ppm product water with 40psi tap pressure. At the new house the mains pressure is 51psi and I'm now getting 1ppm! I knew extra pressure helped but not that much!

    Hi guys, Currently in the carpet and upholstery cleaning business and get a lot of people asking wether I do hard floor cleaning also? Patios, decking driveways etc. So due to the amount of interest I am going to add it to my list of services. Now, the difficult bit. Finding a reliable machine? I have browsed the forum and the Honda GX360 seems to be popular. I have also see on a YouTube page I follow "dirtydriveaway" a Zeta. I realise the Honda is in the £1200-£2000 range and the zera is in the £4000 range. I understand the zeta is 21lpm and the Honda is only around 12-15lpm. How noticeable is this going to be? I'm in an area with quite a low demographic of good earners, so if I'm charging X-amount per square meter, and jack Jones who turns up with his Karcher is 50% cheaper than me gets the work I'm scared to lose the £4000 I've spent on the zeta. As much help as possible please. Links to decent machines between £1000-£2000 Can the GX360 be van mounted? Can I run let's say a 100ft hose from the machine? Return to tank bypass on a honda?
