Brand new basin taps from Screwfix (Swish contemporary range, conventional rotary operation, not cartridge-type). One of them started dripping immediately after install. I fitted flexible tap connectors, using a hack saw to saw off the old pipe. On first use, the tap spewed out some copper filings..so that's probably the cause. Anyway, I decide to renew the washer. So I removed the tap shroud. But I was then unable to turn the nut that holds the tap internals. I used an adjustable wrench. I held the tap spout with my left hand and tried with some force to turn the nut with my other hand, but it still wouldn't budge. This seems unusual for a brand new tap. Any ideas?
Thanks Bruce
