Hi guys, I've always used a merlin, thinking of changing to a 4040, are they cheaper to run, easy to use and set up, and is the water waste alot less so better on water meter, and where do you think is cheapest place to buy, im sure this has been covered a few times but only now looking into it, i use about 600ltrs aday, cheers

A 4040 is more expensive to buy than a Merlin.
You might have to buy a booster pump for the 4040.
But a 4040 should produce less waste water than a Merlin.
A 4040 would probably produce better quality water (lower ppm) than a Merlin so you should use less resin and also save money that way.

I haven't brought enough 4040 systems to say what's best, mines a pure freedom and runs a dream, when the membrane requires changing I buy a quality, recognised make.
For 600 ltrs a day I'd stick with the merlin, great RO's - you get better performance from it if you buy a decent booster pump ( which you'll need for a 4040 anyway ) you merlin will then produce lower TDS and more litres per hour of pure, I'm did around 120 ph winter 150 summer.
