Common Sink Plumbing Problems

Slow or Clogged Drain

Kitchen sink drains accumulate grease, food particles, and soap scum over time. Bathroom sink drains catch hair, toothpaste, and mineral buildup. When water takes a long time to drain — or stops draining entirely — it usually means there’s a blockage in the P-trap or further down the drain line. We don’t just clear the immediate clog; we ensure the drain line is fully clear.

Leak Under the Sink

Under-sink leaks are often traced to the drain basket gasket, P-trap connections, supply line fittings, or the shutoff valves. Even small leaks cause significant cabinet damage and mold growth over time. If you notice water stains, a musty smell, or warping in your under-sink cabinet, it’s worth having a plumber take a look.

Low Water Pressure at the Sink

If only one sink has low pressure, the issue is likely a clogged aerator — the small screen at the tip of the faucet — or a partially closed shutoff valve. If low pressure is affecting multiple fixtures, it may indicate a broader water pressure or supply issue in the home.

Noisy Pipes When the Sink Runs

Banging, rattling, or humming pipes when you run the sink can indicate loose supply lines, water hammer, or a failing pressure regulator. These issues are often easy to fix when caught early but can cause damage to pipe connections if ignored.

Garbage Disposal Problems

The garbage disposal is directly connected to your kitchen sink drain. Issues like humming without spinning, not turning on at all, frequent jams, or leaking at the connection point are all problems our plumbers address regularly.

Rust, Corrosion, or Discoloration

Visible rust around the drain basket or on supply line connections is a warning sign. Corroded fittings can fail without much notice. In Central Texas, hard water accelerates mineral buildup and corrosion on metal components.

Kitchen Sink Plumbing

The kitchen sink sees constant use and carries more plumbing complexity than most other fixtures — a garbage disposal, dishwasher drain connection, filtered water line, and sometimes a hot water dispenser all tie into the kitchen sink plumbing stack.

Our services for kitchen sinks include:

  • Drain cleaning and clog removal
  • Garbage disposal installation and repair
  • Sink basket strainer replacement
  • P-trap repair or replacement
  • Under-sink supply line replacement
  • Shutoff valve repair or replacement
  • Dishwasher drain connection repair
  • Undermount and drop-in kitchen sink installation

Bathroom Sink Plumbing

Bathroom sinks deal with a different set of problems — primarily hair, soap buildup, and hard water scale. The pop-up drain assembly (the stopper mechanism) is a frequent source of issues, either leaking or no longer holding water in the basin.

Our services for bathroom sinks include:

  • Drain cleaning and hair clog removal
  • Pop-up drain assembly repair or replacement
  • Supply line and shutoff valve replacement
  • Vessel sink and undermount sink installation
  • Pedestal sink installation
  • Vanity sink replacement during remodels

Sink Installation Services

Whether you’re upgrading a kitchen sink, remodeling a bathroom, or adding a new sink to a utility room or wet bar, our team handles installations from start to finish — including the rough-in connections, drain configuration, and faucet hookup.

We work with all standard sink types:

  • Drop-in (self-rimming) sinks
  • Undermount sinks — kitchen and bathroom
  • Vessel sinks
  • Farmhouse and apron-front kitchen sinks
  • Pedestal and wall-hung bathroom sinks
  • Utility and laundry sinks

If you’re purchasing a new sink for a remodel, we can advise on compatibility with your existing countertop and drain rough-in before you buy — saving you the headache of a return.

Hard Water and Sink Plumbing in Central Texas

Hard water is a fact of life in Buda, Kyle, and San Marcos. The mineral content in our water supply causes scale buildup inside faucet aerators, around drain baskets, and along supply line connections. This buildup reduces flow rates, accelerates corrosion, and eventually causes premature failure of fittings and valves.

If you find yourself frequently dealing with mineral-related issues in your sinks, a water softener or whole-home filtration system may be worth discussing with our team.

When to Call a Plumber for Sink Issues

Not every sink problem requires a plumber, but some should prompt a call sooner rather than later:

  • There’s active water pooling under the sink or in the cabinet
  • Multiple drains in the home are slow or backing up
  • The shutoff valve under the sink won’t fully close
  • Water pressure has dropped noticeably at one or more sinks
  • You smell sewage or mildew coming from the drain area
  • Drain cleaning products haven’t resolved the slow drain
  • The garbage disposal leaks at its mounting collar

Frequently Asked Questions — Sink Plumbing

Why does my kitchen sink drain slowly even after I clean the P-trap?
If clearing the P-trap doesn’t resolve the issue, the blockage is likely further down the drain line — past the point where the sink connects to the larger drain stack. This type of clog typically requires a drain snake or hydro-jetting service to clear effectively.

Is a slow bathroom sink drain a big deal?
A slow bathroom drain is usually caused by hair and soap buildup in the upper part of the drain. While it often starts as a minor inconvenience, it can worsen quickly and lead to standing water. It’s worth addressing before it becomes a full blockage.

My sink has low water pressure but the rest of the house seems fine. What’s causing it?
The most common cause is a clogged faucet aerator — the small mesh screen at the end of the faucet spout. Unscrew the aerator and rinse it with vinegar to dissolve mineral buildup. If that doesn’t help, a partially closed shutoff valve or a deteriorating faucet cartridge may be the culprit.

Can you install a new kitchen sink in an existing countertop?
Yes. Sink replacements in existing countertops are a routine part of our work. The main considerations are the sink cutout dimensions, the type of mounting (drop-in vs. undermount), and whether your existing faucet connections are compatible with the new sink. We’ll assess everything before and during installation.

What causes that sewage smell coming from my bathroom sink?
A sewage odor from a drain is often caused by a dry P-trap (the curved pipe under the sink that holds water to block sewer gases). If the sink isn’t used regularly, the water in the P-trap evaporates. Running the water for 30 seconds usually resolves it. If the smell persists, there may be a venting issue or a cracked drain fitting.

How do I prevent garbage disposal drain clogs?
Run cold water before, during, and for 15–20 seconds after using the disposal. Avoid putting fibrous foods (celery, artichokes), starchy foods (potato peels, pasta), grease, or large amounts of food at once down the disposal. Grinding a handful of ice cubes occasionally helps clean the blades and reduce buildup.
