Faucets drip constantly. Drains back up. Basins crack. Fixtures look dated. Rooter & Plumbing Masters handles every sink issue throughout West Covina—repairs that stop leaks, replacements that update bathrooms and kitchens, and installations during renovations.

Two decades working on West Covina sinks means we know what breaks, what works, and how to get jobs done efficiently.

Faucet Internal Wear
Drips start small—barely noticeable drops—then progress to steady wasteful streams. Different faucet types fail differently. Compression models need washer replacement. Cartridge types require new cartridges. Ball faucets fail at seals. Ceramic disc units eventually crack. Diagnosing which specific component wore out prevents buying wrong parts that don’t fix anything.

Drain Blockages
Kitchen drains accumulate grease, food debris, and soap creating stubborn clogs. Bathroom sinks collect hair mixed with toothpaste and cosmetic products forming equally frustrating blockages. Simple surface problems respond to basic snaking. Deeper issues—corroded assemblies, poor venting, deteriorated pipes—need different approaches.

Connection Leaks
Sinks have multiple connection points creating multiple leak possibilities. Supply lines develop pinholes. Shutoff valves weep at stems. Drain basket strainers leak. Pop-up assemblies drip. P-traps fail at slip joints. Water under sinks damages cabinets progressively until small leaks become major problems.

Basin Structural Damage
Dropped items crack porcelain. Heavy loads stress undermount adhesive bonds until sinks drop. Wall-mounted models sag when brackets loosen. Composite materials chip at edges. Once basins compromise structurally, replacement beats attempted repairs.

Disposal Failures
Garbage disposals jam from debris, leak at mounting gaskets, fail from burned-out motors, or generate excessive noise from worn components. These mechanical units integrate plumbing, electrical, and mechanical systems requiring comprehensive diagnosis.

Faucet Work
Stopping drips means replacing specific failed internal components. We diagnose which parts actually wore out, source correct replacements, disassemble properly, install new components, and test thoroughly. Sometimes complete faucet replacement makes more sense than expensive repairs on cheap worn fixtures.

Drain Clearing
Kitchen and bathroom drains need different approaches. We snake mechanically, use appropriate treatments when suitable, replace failed drain components, and address underlying venting or slope problems causing recurring clogs.

Leak Fixes
Finding leaks requires systematic checks—supply connections, shutoff valves, drain assemblies, P-traps. Repairs match sources: tightening connections, replacing supply lines, resealing drains, replacing failed parts. We fix root causes, not just symptoms.

Disposal Service
Jammed disposals often just need debris cleared and reset buttons pressed. Failed motors need complete unit replacement. Leaking gaskets need replacement with proper tightening. We diagnose accurately rather than automatically suggesting expensive replacements.
