    Digi Varistream is all i know, its been good to me over the last two years. It took me a while to figure out how to run the flow and pressure settings properly but now i have its brilliant.
    As with any system make sure there's no air locks or leaks otherwise you'll be chasing your tail settings-wise.
    Only way i can think to improve it is to have remote control which is where i will go when its time to replace the digi vari.

    If I was buying a controller now, I would buy the 'new' analogue unit that Spring makes. Having the 2 dials on the front (flow and pressure) makes sense to me. Simple easy adjustment. I would run it along side a separate on/off switch as we used to do with our original analogue Varistreams.

    http://www.gardinerpolesystems.co.u...Pump-Flow-Controller--LIQUIDLOGIC_ANALOG.html

    What I also like about this is that you have an 'infinite' range of motor speed settings. With our digital Varistreams (which have given us excellent service) we don't have the same level of control. For example; I run my pump on 4 as 5 wastes too much water. I would like a setting between 4 and 5 which the Varistream hasn't got.

    Also, the latest Varistreams consume current even when the unit is switched off, so they need an extra cut off switch to be added into the system to stop this.

    Flow controllers have come a long way since their introduction. Spring have a range of units that not only control water flow and pressure, but can also include a split charge relay for an auxiliary battery, frostat and the battery voltage indicator to name just a few. Whilst an 'all singing and dancing' controller would appeal to some, I'm not sure I would put all my proverbial eggs in one basket buying a unit that does everything in one package. I would be concerned that you will loose everything if the unit failed.

    Spruce thats what took me a while to figure out, i had exactly the same problem apart from i was looking for 3.5, as i run on 3. But 3 is not enough but 4 is too much, as in its fine for rinsing but goes through water too fast

    So i finally found i really good setting, i started treating the A-F settings like the decimal settings so i have ended up using No 3 and somewhere between D and F. But if there is even the slightest air lock then the flow is cr@p.
    So every morning i turn the controller up to 8 or 9 to pressurise the reel, then while its still pumping or paused disconnect the outlet from the di then set it back to 3 and if it pause after 20-30 secs i know the air is out of the system, it saves all the sucking lol
