    No as i have good pressure
    Never measured it but ro kicks out at 4ppm from just about 300 (varies from 290-310)
    I just leave the waste open a touch and it is fine

    Realistically you could do 800l per day with the waste open about 1/4 and have low tds to go through di with no worries
    I measueed it at 1000l per day in 20 hours with the waste shut by measuring how long for a 25l drum but it will be a little slower with the waste open a touch but prolongs the membrane life also

    Yip I have a Collins 450gpd worked faultlessly apart from a little leak I sorted in seconds for the last 4 months, changed the filters four weeks ago as recommended (very inexpensive) maybe not the fastest to filled a tank certainly does everything I need my tap water is 6.5 psi and take approx 4 hours to fill 200 litres.
