Steps
Turn off the hot and cold supply valves under the sink. Open the faucet to drain the line and relieve pressure before you take anything apart.
Pry off the handle index cap, then remove the handle screw with a Phillips or Allen key. Pull the handle straight off.
Use an adjustable wrench to loosen and remove the bonnet or retaining nut. Keep the faucet body steady so you do not twist the supply lines.
Pull the cartridge straight up by its stem. Do not twist it or lever a screwdriver against the faucet body, which can crack the valve.
If it will not move, fit a Delta cartridge puller over the stem. Thread it on and turn the puller nut to draw the cartridge out evenly.
For white mineral crust, soak a cloth in white vinegar and wrap it around the cartridge for 15 to 30 minutes, then try the puller again.
Clean the inside of the valve body with a soft brush and vinegar. Rinse well and wipe away loose debris before fitting the new part.
Push the new Delta cartridge in with its tabs lined up. Refit the nut, handle and screw, then turn the water on slowly and check for leaks.
Tips and common mistakes
Turn off both supply valves and open the faucet before you start, so hot water cannot surprise you.
Use a proper cartridge puller instead of prying with a screwdriver, which can crack the faucet body.
Avoid petroleum-based oils on the cartridge O-rings; use a little food-grade silicone grease instead.
If the cartridge breaks off inside the valve, stop and call a plumber rather than drilling it out.
Questions
Why is my Delta faucet cartridge stuck?
Mineral scale, corrosion or a dry O-ring can lock it in place. Vinegar and a cartridge puller usually free it without force.
Can I use WD-40 to loosen a stuck cartridge?
It is not the best choice for drinking water parts. Use white vinegar to dissolve mineral buildup and keep lubricants food-grade.
How do I find the right replacement cartridge?
Look for the model number under the handle or on the faucet base, then match it to a Delta cartridge. Take the old cartridge to a hardware store if the number is worn.
