Remove Old Valves, Escutcheons, and Supply Lines

What happens here

Attempt to turn the old shutoff valves. If they are seized or difficult to turn, proceed with caution. Use pliers or side cutters to carefully break off and remove the old escutcheon plates from around the PEX pipes. Then, disconnect the old braided supply lines from both the old shutoff valves and the sink faucet connections under the sink, taking care not to damage the faucet connections or the PEX pipes protruding from the wall.

Goal: Disassemble the old plumbing components from the PEX pipes and sink faucet.
