Not a lot of time, so just some of my stacked bowls, before the plumber is coming to check, if our water taps have to be replaced. "Designer" taps, but poor quality.They seem to be water soluble! :-(
Addendum: we need to replace them,... what a waste. It's not only about money, it is about trying to live a sustainable behaviour and lifestyle, but throwing away something, that should last much longer.
