Task 1 — Replacing a faucet cartridge (bathroom)
A precise, reproducible sequence that avoids drips and wasted water.
Timeframe: 60–90 minutes. Tools: adjustable wrench, cartridge puller (or a pair of needle-nose pliers), bucket, towels, silicone lubricant, replacement cartridge (specific to model), plumber’s grease, adjustable pliers.
- Shut off the hot and cold water at the angle stops. Open the faucet to relieve pressure; verify no water remains in lines.
- Protect the area with towels; place a bucket under the valve to catch residual water.
- Remove the decorative handle with a small screwdriver; extract the set screw; lift off the handle.
- Use the cartridge puller or pliers to extract the old cartridge. If stubborn, tap lightly with a rubber mallet to free.
- Install the new cartridge with plumber’s grease on O-rings; reassemble in reverse order.
- Turn on water slowly; check for leaks. If drips persist, reseal with a bead of silicone around the escutcheon plate.
Material cost range: replacement cartridge typically $15–$40, depending on brand (MOEN, Delta, Kohler). Silicone sealant tube: $4–$6. Optional cartridge puller: $8–$20 if not included with tools.
Final check: hot and cold flow balanced; no leaks behind the escutcheon; print a quick budget note for future replacements (estimate $0.50 per month for maintenance, if balanced well).
