Bought at a plumbing supply shop, hooked up and installed without a hitch. Did the washing as directed. The first few times I turned on the tap, murky white water gushed out and clogged the drain for many seconds. This seems to be a normal property of filter elements, and a good washing has remedied the situation. There is no scale, no unusual flavors, and no harsh aftertaste in the water. Let's have a look at the filter tool. The strength of 12 cubes is impressive, but unlikely.
