thanks all...got some other advice from some people. Feedback in point form: Brita C150 It included all the tubing needed to connect to the water outlet, the machine should've included a braided steel hose to go to the machine Bunnings had a brass T-joiner that did the job along with lots of good-quality Teflon tape (not the stuff included with the filter - it's crap) Brita does include a pressure reducer and shut off valve The 3/8" valve from ECM Sync goes straight into the Brita C150 The output to water mains has a 1/2" valve to plug into the T-Junction or Water Tap. Just need the right brass/tape to connect Waste For the waste you'll need an additional part (I think it's called the "drain waste kit" or similar), basically an open-topped plastic box that sits under the drip tray. You will need to drill out the drip tray - there's an indent for that, my tip here is to source a rubber plug and drill to the same diameter so it's simple if you move the machine and want to run the drip tray again. And keep the hole small - well under a cm - to limit the flow rate. The outlet from the drain box is small, so it will fill up and overflow if a lot of water goes through. I'd even start at 4mm or so, you can always drill it out further later on if needed.
