LMSC hi, machine still waiting to be sent, another boiler rebuild and mostly fine apart from water coming up through the springs..
My RO is good, but I went the cheap route (cost about £220 from memory, waterdrop g2)so it’s based on a unit that has a pump to generate the pressure. It sits behind the fridge freezer, but can definitely hear it. Runs for about 5 seconds whenever the tank calls for water.
