It's attached to the water line at the back of the fridge. Comes out the water/ice dispenser at the front. please log in to view this image
I wouldn't want to drink the tap water here. Not all fridges have ice makers and water/ice dispensers on them here but I'd say maybe 90% of them do... At least here in the South they do.
Ah you have a plumbed in fridge freezer. You can get some really good ones with both water and ice dispensers that don't require plumbing. Ours has a water dispenser and isn't plumbed in. I think the requirement is for the water supply to be no more than 1.5 metres away and we don't have that configuration in our kitchen.
That's what I'm talking about. I think all new machines have that function but it requires you to run it as a programme with drum cleaning powder or liquid, it doesn't clean itself even though it's called 'self clean'. The reason being - on itital use - to get rid of any oily residue or other substances still in the machine from the manufacturing process and subsequent runs of the programme to keep it bacteria free.
Maybe yours doesn't need any cleaning powder. The one we just bought is the first I can remember needing powder in the first clean. We didn't know such stuff existed
Says to obtain better results put linescale remover into detergent compartment. Doesnt say it's definitely needed though.
We've got boss water in Liverpool Never had any problems with limescale in washing machines and never seen it in the kettle ever. If you have hard water I'd do a limescale dose every now and again in the soap drawer.
We have very soft water. (Have to add magnesium salts, chalk, and baking soda to my water to prevent my snail's shells from erroding)... Instead of limescale we get sand and grit come through our pipes and sometimes clogs up shower heads or appliances.
Pet might be a strong word... they keep the aquarium clean and produce good bacteria that help micro-fauna that is eaten by young fish and shrimp.
Funnily enough I do know someone who has pet snails. Started off taking them home to look after in school holidays and the school decided they didn't want them back. African snails or something like that - they live in a tank but not in water.
