Our kitchen taps are dripping. I've just checked and they've got DTC 32 cartridges. I can match up replacements, I'm sure, with a bit of reading, but why? What is the advantage of these abominations over traditional taps that took the 1p washers that I've fitted so many times before? And why does it have to be so complicated that, I read, professional plumbers will often suggest replacing the taps?
Can I still buy a kitchen mixer tap that takes proper washers? For one thing, it would be more environmentally friendly!
