This afternoon, I installed a new bathroom faucet in the master suite that the customer had purchased. The faucet was a Moen Boardwalk model with a widespread configuration. I carefully removed the old faucet, made the necessary supply line and drain connections, and ensured proper sealing and operation of the new fixture. I also repaired a persistent leak under the guest bathroom sink by replacing the faulty drain gasket and tightening the drain assembly. The plumbing systems are now functioning properly.
