We have a standard 'mains' pipe that goes under the floorboards to the fridge location and there is a 1.5m connecting pipe to the actual unit.
Our filter is easily replaceable and has a light to warn it needs changing.
The water itself isn't chilled as it comes straight off the mains. But it's filtered and the ice is just there. I actually thought our ice maker was bust at first. Until I realised it was going to take a few hours for it to create enough ice to be dispensed
But it's ace and I love the convenience - as do the rest of the family. The Maytag seemed a very good buy... £900. Most Maytags are usually £1500 upwards. I think this may have been a new entry level model for the UK market as there were a few internet sites selling them.
It seems you are paying a lot for special finishes on some of these fridges - especially some of the Samsung and LG models which appear to be identical except that some have mirrored doors or stainless steel all round.
A lot of the cheaper units have very plain sides, which won't look to great if the fridge is going to be free standing.
