Preserve the useful detail
Dry the area and observe while idle, under hot and cold flow, and while the basin drains. Record brand, hole layout, and first wet point.
The decision on display
Do not transfer the hazard
Avoid overtightening old parts or operating a poor stop. Keep water away from cabinet power and preserve the finish.
Make the proposed work comparable
Separate cartridge, seals, aerator, supplies, stops, faucet replacement, counter access, finish protection, and tests.
