    Okay if your mate has the same vessel then use his head and riser tube to insert into your vessel. If it comes out zero then you know it’s your vessel internals

    Variflo + controller not calibrating

    There is an issue with the Univalve and Controllers. The ones I have set up I have had to manually change the settings to get it work properly. This is what I have found. Works fine at low speed but when you increase it it then goes ‘de’. Not knocking the Univalve but I have seen an increase with pump and controller problems with this set up. Something I’m keeping an eye on.

    Do you have a Univalve

    When you see the Calc sign C30 then use down arrow to take it to zero then it will auto calibrate.
  7. You really need the specification of the pump to determine if it is the correct pump to do the job. The pump might say 11 litres per minute but it is important to know what the closed flow rate is at xxx psi. For example if it only does 6 litres at 100 psi then you would get around 2.5 litres of pure so with this pump would be more beneficial to link the waste to the second membrane as the pump would not be powerful to feed two membranes. The Cleaning Warehouse description is not that very clear. I've got a lot of notes back at the office so will try and reply back next week.

    Simple test. Get a bag and wrap it around the bottom filter and insert back into vessel. Turn the tap on and no water should be coming out the outlet. If it is then the internal riser and head are faulty

    Changed filters pressure has dropped

    5 micron in the normal rating.

    Wrong micron size will cause this

    Air lock in R.O??

    On them membranes in the shaft there is a little lever of some sort. I think maybe wrong they have to be pushed in for pure water to be produced.

    Are Univalves temperamental?

    In Industry any valve or hose etc.. will have been tested and accredited a PSI rating. For example some John Guest fitting will only take max 150 PSI. Whereas the Univalve has had not had this test and a local guy has been through several of these. He likes to use high flow so maybe an issue the pressure is too much.

    Are Univalves temperamental?

    This may or may not be connected but having a number of customers have issues with pump issues in not turning off and burning out. All use the univalve it may or may not be a problem but would be interested if anyone has had pumps go within 6 months of using it.
