Water2buy W2B780 water softener

Been offered a few water softeners cheap, I’m in Medway but could potentially post. Not sure if they’d be any use to anyone, they are brand new boxed they are a water2buy - W2B780 They back wash automatically when needed as well. Suitable for a 10 person household £400 each but I’m sure I could get the price down if I was going to take them all
