The old membrane was a Filmtec one, it used to be ok, taking water down to 15-20, it's 5 years old now though and when I took it out it was pretty slimy, as was the inside of the tube.
Not sure of the water pressure as I haven't got a guage on it but it's fairly good, on an open tap it's running at around 10ltr per min into a bucket.
I still need to get an auto cut off solenoid fitted but not sure what bits I need to do it or where to get them from, any help would be appreciated.
