I having trouble connecting a new sink. The 1/2 inch connectors are
okay, but the 1/4 inch tubing from the (single-control handle) faucet
to itself leaks, and I'm afraid I'll twist and break the tubing if I
turn it too much, since there's nothing to hold the tubing while I turn
the nut. Was it a mistake to buy this sink with it's 1/4 inch
connectors, or should I just keep tightening it fearlessly?
