Peerless Single Handle Bathroom Faucet in Chrome P188621LF

The copper tubing for the water supply is attached to the underside of the faucet using o-rings mounted in a phenolic block, which can be a potential source of leaking over time. Most standard faucets have a metal block the pipes are brazed to, eliminating any possibility of leakage. The faucet itself works properly and there were no leaks after installation. But I caution new purchasers of this particular faucet not to place undue stress on the tubing as it could result in a leak around the o-rings where they attach to the phenolic block. So use care when installing.

It appears that this faucet may have been a return. The plumber installed this faucet and it started leaking through the faucet.
