Setup and Installation
- Turn off Water Supply: Locate the main water shut-off valve for your home or the specific shut-off valves for the faucet you are working on. Turn them off completely.
- Drain Faucet: Open the faucet handles to drain any remaining water from the lines.
- Remove Faucet Handle: Depending on your faucet model, remove the decorative cap (if present), then unscrew the handle screw and pull off the handle.
- Remove Packing Nut: Use an adjustable wrench to carefully loosen and remove the packing nut that secures the old stem in place.
- Extract Old Stem: Carefully pull out the old faucet stem. Note its orientation and any washers or O-rings.
- Inspect and Clean: Inspect the faucet body for any debris or mineral buildup. Clean the area thoroughly before installing the new stem.
- Install New Stem: Insert the new LASCO S-1008-3 Harcraft Stem Assembly into the faucet body, ensuring it is properly seated.
- Replace Packing Nut: Hand-tighten the packing nut, then use a wrench to tighten it slightly more, ensuring a snug fit without overtightening.
- Reattach Handle: Place the faucet handle back onto the stem and secure it with the handle screw. Replace any decorative caps.
- Restore Water Supply: Slowly turn the main water supply back on. Check for any leaks around the faucet base and stem.
- Test Faucet: Operate the faucet to ensure proper water flow and temperature control.
Operating Instructions
The LASCO S-1008-3 Harcraft Faucet Stem Assembly functions as the internal mechanism that controls water flow and temperature within your Harcraft faucet. Turning the faucet handle clockwise or counter-clockwise will open or close the water valve, allowing water to flow or stop. For hot/cold applications, the stem's design allows for the appropriate water temperature control when used in its designated hot or cold side.
Maintenance
- Regular Inspection: Periodically check the faucet for any signs of leaks around the handle or spout.
- Tighten Connections: If minor leaks occur, gently tighten the packing nut. Avoid overtightening, which can damage the stem or packing.
- Replace Worn Parts: Over time, internal washers or O-rings within the stem assembly may wear out. If persistent leaks or difficulty in turning the handle occur, consider replacing the stem or its internal components.
- Cleaning: Keep the exterior of the faucet clean to prevent mineral buildup that could affect handle operation.
