BWT Polyphosphate Compression Connection Combi Care Scale Inhibitor 15mm is rated 2.5 out of 5 by 2.
Rated 1 out of 5 by from Doesn't even get wet Had one of these fitted 10 years ago but read recently that they get easily blocked. Last week I bought a refill and after removing the old cartridge I turned on the stopcock. Alas no water came out. I am now wondering how many years I have been replacing these cartridges when they don’t even get wet.
