Installation (Setup)
Tools Recommended: Adjustable wrench, screwdriver, penetrating oil (optional), cleaning cloth.
- Turn off Water Supply: Locate the shut-off valves under the sink and turn them clockwise until the water flow stops completely. Turn on the faucet to drain any remaining water and confirm the supply is off.
- Remove Faucet Handle: Depending on your faucet model, you may need to pry off a decorative cap to expose a screw. Use a screwdriver to remove the screw and lift off the handle.
- Remove Packing Nut/Bonnet Nut: Use an adjustable wrench to carefully loosen and remove the packing nut or bonnet nut that secures the old stem in place.
- Extract Old Stem: Gently pull the old stem out of the faucet body. If it is stuck, a slight twisting motion or penetrating oil may help. Note the orientation of the old stem for reference.
- Inspect and Clean: Inspect the faucet body for any debris or mineral buildup. Clean the area thoroughly with a cloth.
- Install New Spring and Seat: Place the new spring into the faucet body, followed by the new rubber seat. Ensure they are seated correctly at the bottom of the valve opening.
- Insert New Stem: Carefully insert the Danco 18590B stem into the faucet body, ensuring it aligns with the spring and seat.
- Replace Packing Nut/Bonnet Nut: Hand-tighten the packing nut or bonnet nut over the new stem, then use the adjustable wrench to tighten it securely, but do not overtighten.
- Reattach Faucet Handle: Place the faucet handle back onto the stem and secure it with the screw. Replace any decorative caps.
- Restore Water Supply: Slowly turn the water supply valves back on. Check for any leaks around the faucet base and connections.
- Test Faucet: Operate the faucet handle to ensure proper hot and cold water flow and shut-off.

Operation
The Danco 18590B 3S8H/C Hot/Cold Stem functions as the control mechanism for water flow and temperature in your faucet. Turning the faucet handle will rotate the stem, which in turn opens or closes the water passages and mixes hot and cold water as per the handle's position. Ensure the handle moves smoothly and water flow is consistent.
Maintenance
- Regular Inspection: Periodically check your faucet for any signs of leaks or drips. Addressing minor issues promptly can prevent larger problems.
- Cleaning: If water flow becomes restricted, mineral deposits may be accumulating. Disassemble the faucet and clean the stem and surrounding areas with a mild descaling solution or vinegar.
- Avoid Overtightening: Do not overtighten the faucet handle, as this can prematurely wear out the stem's internal components.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Faucet drips or leaks | Improperly seated stem, worn O-rings/seat, or loose connections. | Ensure the stem is fully seated. Check and replace O-rings or seat if worn. Tighten all connections, but do not overtighten. |
| Faucet handle is stiff or hard to turn | Mineral buildup or lack of lubrication. | Disassemble and clean the stem and faucet body. Apply a small amount of plumber's grease to the O-rings. |
| No water flow or reduced flow | Clogged aerator, debris in the stem, or water supply issues. | Clean the faucet aerator. Check the stem for any obstructions. Verify water supply valves are fully open. |
