Laundry tubs are convenient, if they leak, it can damage your floor and increase water bills. A leaky laundry faucet wastes around ten thousand gallons of water annually.
Laundry room faucets often aren't constructed from strong materials, which makes them prone to faster wear and tear than standard taps. You should be able to fix a leaky two-handle laundry faucet yourself by following these tips.
Prepare to Fix the Faucet Leak
To fix the leak, gather:
- plastic gloves
- Phillips screwdriver
- adjustable pliers
- seat wrench
- stem washer
- white vinegar
- spray lubricant
- pipe thread compound
Shut off the water supply from the valves, which are commonly round or oval knobs located below the tray. If you can't find the knobs, look in the basement, or turn off the main water supply from the valve on the water meter. Relieve water pressure by turning on a tap.
Remove the Faucet
Most laundry tub faucet leaks occur at the handle stem. The handles on laundry faucets commonly have handles with visible screws, but they still may be under a cap. If there is a cap, untwist it by hand, or grip it with pliers wrapped in a cloth to avoid scratching the surface.
Use the screwdriver to detach the screws, and remove the handles. Look for two hexagonal nuts on the valve stem, and remove the top nut, or packing nut, by rotating adjustable pliers to the left, then detach the second nut.
If hardware is hard to turn, coat it with some lubricant, let it stand five minutes, and try again. Grasp the end of the stem with the pliers, and pull the faucet from the tub. Replace damaged or rusted packing nuts or faucet screws.
Inspect the Valve Stem
Check the valve stem sea and the metal retainer that holds the washer on the valve stem for dirt and mineral deposits. Use a file to clean the retainer.
Feel the valve stem seat for mineral deposits. Valve stem seats that feel rough commonly indicate mineral deposits. To clean the valve stem seat easier, rotate the seat wrench it to the left to remove it. Soak the seat in white vinegar overnight, or replace corroded parts.
Inspect the washer and retention screw. Unscrew damaged washers and retention screws from the stem, and replace them with new ones. Coat new or existing valve stem threads with pipe compound, secure the stem to the faucet, and add several drops of spray lubricant to the stem. Reinstall the handles, turn on the water and try the sink again.
