LITTLE THINGS. EVERY SINGLE DAY.
Faucet &
sink repair.
The tap you use every morning should just work. We find the leak, explain the fix, and help you get back to the small comforts of home.
Repair, replacement & under-sink connections. Clear pricing before work.

A drip. A puddle.
Two different stories.
Notice where the leak starts and whether the faucet is running. That helps us follow the pressurized supply or the drain below the basin.
It won’t stop dripping.
The cartridge, valve seats or seals may not be closing properly. The faucet design determines the repair.
Look inside the cartridge ↗ WHEN IT’S RUNNINGWhere did the flow go?
Start with the outlet and compare hot with cold. Debris, a supply restriction or the cartridge can change the flow.
Inspect the outlet ↗ BELOW THE SINKThe cabinet is wet.
Supply water, a drain connection, the sink seal or a hose can leak. We trace the source before choosing a part.
Explore underneath ↗One little handle.
A lot happening inside.
Turn the faucet around. Open its shell. Separate the parts and follow the water from the supply lines to the stream.
Hot and cold enter separately. The cartridge controls what reaches the spout. Choose a demonstration or explore a labelled part.
Opening the faucet cutaway…
Choose a part below to take a closer look.
Lift the handle to open the flow and turn it to blend hot and cold water. The colors trace those water paths through the cartridge.
WHAT IT DOES
The cartridge controls the water.
The cartridge is the replaceable valve inside the faucet. Moving the handle slides ceramic discs inside it, opening water passages and blending hot and cold water.
WHAT YOU MIGHT NOTICE
A steady drip with the handle off, a stiff handle, or leaking around the handle can point here. Identify the faucet model to match its service parts.
WHAT A REPAIR INVOLVES
Identify the faucet and inspect the cartridge and its seals. Use the correct service part, then test shutoff, mixing and leaks.
This cutaway shows a single-lever ceramic-disc faucet. Open the shell and separate the parts to see how the handle moves the discs and blends the water.

Cartridge
The cartridge is the replaceable valve inside the faucet. Moving the handle slides ceramic discs inside it, opening water passages and blending hot and cold water.
Identify the faucet and inspect the cartridge and its seals. Use the correct service part, then test shutoff, mixing and leaks.
Ceramic discs
One ceramic disc stays fixed; the handle moves the other. As the holes in the discs overlap, they open a path for water. Smooth mating surfaces seal when the faucet is closed.
Match the cartridge to the faucet model. Its water openings, seals and stem must line up with the body and handle. The worn cartridge usually comes out as one assembly.
Seals & O-rings
Seals keep the hot, cold and mixed-water passages separated and seal the cartridge to the faucet body. Other designs also have spout O-rings.
Find the origin, match the seal or cartridge to the model, and check it under running-water pressure.
Aerator
The outlet insert shapes the stream. Its screens and flow-control passages can collect debris or mineral deposits.
Inspect the outlet insert for trapped debris or scale, clean or replace it, then check that the stream has recovered.
Supply lines
Separate hot and cold connectors feed the cartridge. Their connections are pressurized even when the faucet handle is closed.
Identify the leaking connection and check shutoff operation before disturbing it. Replace damaged connectors or valves as needed.
Mounting & base
The mounting shank, gasket and retaining hardware secure the faucet through the sink or counter. A loose faucet can strain its connections.
Secure the mounting hardware against the underside of the sink or counter. Replace a damaged base seal and check the faucet body for cracks before reconnecting it.
Drain & stopper
The drain flange seals to the sink. The stopper opens and closes the drain; the tailpiece carries used water into the trap.
Inspect the flange seal, stopper and drain assembly. Diagnose a slow drain separately from low faucet flow.
P-trap
Water held in the trap helps block sewer gas. Slip-joint washers seal the removable connections; the trap arm leads toward the wall drain.
Check alignment, washers and pipe condition. Check farther along the branch for blockages that need cleaning.
The details matter.

More than the tap
A sink that won’t drain or a disposal that won’t work needs its own approach. Replacing the bowl? Check its mounting and plumbing fit first. We do not install or remount undermount sinks.
