Plumbing Services in West Covina, CA

Mike Diamond Plumbing handles everyday repairs and urgent plumbing problems in West Covina. Our plumbers diagnose leaks, damaged pipes, toilet and fixture problems, garbage disposals, gas lines, water-quality concerns, and other household plumbing issues. We focus on identifying the cause and explaining appropriate repair or replacement options.
  • Emergency plumbing: 24/7 availability for burst pipes, overflowing toilets, major leaks, backups, and loss of water service.
  • Pipe repair and replacement: Diagnosis and service for leaking, corroded, damaged, or aging water lines.

Garbage Disposal Repair and Installation in West Covina

A jammed, humming, leaking, or nonworking garbage disposal can interrupt kitchen use and may contribute to a sink that drains poorly. Mike Diamond Plumbing provides garbage disposal repair and installation for West Covina homes. We inspect the disposal, reset and electrical connections, mounting assembly, drain connections, and related sink plumbing to identify the source of the problem. When repair is practical, we explain the recommended work; when a damaged or aging unit should be replaced, we can install a replacement with secure plumbing and electrical connections.

Leak Detection and Slab Leak Service

Hidden water leaks can raise water bills and damage walls, cabinets, flooring, or foundations before the source is obvious. Our leak detection service helps locate concealed plumbing leaks, while slab leak evaluation addresses signs such as warm floor areas, unexplained water use, damp flooring, or the sound of running water when fixtures are off.

Drain Cleaning and Sewer Service in West Covina

Slow drains, recurring clogs, gurgling fixtures, sewage odors, and wastewater backups can indicate a blockage or damaged line. Our West Covina drain and sewer team can investigate the cause and recommend cleaning, repair, or replacement service.
  • Drain cleaning: Clear common obstructions and restore flow to sinks, showers, tubs, toilets, and household drain lines.
  • Emergency drain and sewer service: Help for urgent backups, overflows, and sanitation concerns.
  • Drain and sewer repairs: Investigate roots, buildup, corrosion, offsets, or damaged piping and explain repair options.
  • Drain and sewer replacement: Replacement recommendations when inspection shows a line cannot be reliably restored with cleaning or localized repair.

  • Water heater repair and maintenance: Evaluate heating, ignition, leaking, sediment, and performance problems.
