I have installed pop-up wastes in several sinks the past few years, both in my IP and in my PPOR. For those who don't know what I'm talking about, I mean the newer-style drainage holes in porcelain sinks:
My perception is that the drains below these wastes are significantly more prone to blockages than the older grid-style wastes. Has anybody else noticed this, and do you know why? I wondered if it's because hairs, for example, would get caught on the older grid-style ones, and be pulled out when cleaning the sink, whereas these ones allow the hairs to go down into the drain. But that's just my theory... could be complete rubbish.
I'd never had problems with blocked vanity sinks before, but I've now had two instances where a plunger and draino-type chemicals haven't been sufficient to unblock, and at my IP had to have a plumber remove and clear out the trap. (Unfortunately I wasn't there and didn't ask what it was that was blocking the trap.)
Any suggested remedies?
