Arrived and found that the upstairs master bath lavatory faucet is old, worn out and constantly running from the hot side. Customer does not want to rebuild or replace the faucet at this time since she is planning to remodel the bathroom soon. Attempted to turn off the hot side stop valve. When off, the valve starts leaking and doesn’t turn off. Also found a leak coming from the pop up stopper rod. Replaced rod as a courtesy. Replaced the hot side stop valve and supply line. Left valve turned off at customers request.
