Clogged Sink Repair in Alhambra, CA

A sink that drains slowly or backs up is usually blocked within a few feet of the drain: in the trap, the pop-up stopper, or the short branch line into the wall. We clear it there, reseal the joints, and tell you what was in it.

What we do

  • P-traps removed, cleaned and resealed
  • Pop-up stoppers and linkages cleaned and adjusted
  • Branch lines to the wall cleared with a hand auger
  • Kitchen sinks with disposals unjammed and cleared
  • Double-sink and continuous-waste kits rebuilt
  • Leaking slip joints and washers replaced

In Alhambra homes

The City of Alhambra’s 2025 water quality report lists total hardness at 240 ppm, which the U.S. Geological Survey counts as very hard. Hard water leaves scale inside drain pipes that catches soap, hair and grease and narrows the line over time. In older homes, about 77 percent of the city’s housing per a city report, those pipes may also be original galvanized steel that has narrowed from the inside.

Bathroom sinks

Hair and soap wrapped around the pop-up stopper is the usual cause. We pull and clean the stopper, clear the trap, and adjust the linkage so the stopper opens fully.

Kitchen sinks

Grease and food build up in the trap and the branch. We clear the trap, run a hand auger into the line, and check the disposal and dishwasher drain connections while we are there.

Why chemical cleaners make it worse

Caustic drain cleaners rarely clear a full blockage, and the chemicals sit in the trap when we open it. If you have used one, tell us so we take care opening the drain.

Old galvanized drains

Older steel drain lines narrow with scale and rust. Clearing them helps, but a line that clogs again soon may be worn inside; we tell you if that is what we see.

Keeping drains clear

Wipe grease into the trash, use a hair catcher in bathroom sinks, and run hot water after using the disposal. Those habits keep most clogs away.

What goes to a plumber

Main line stoppages, sewer backups and anything needing a powered drain machine through the cleanout go to a plumber or drain service.

What we find

Hair, soap scum, grease, coffee grounds, eggshell grit and small objects dropped past the stopper. Telling you what came out helps keep it from happening again.

Tub and shower drains

A slow tub or shower drain often clears the same way, at the stopper and trap. We can clear those during the same visit if you mention them.

Gurgling and slow sinks together

If several fixtures drain slowly or gurgle at once, the blockage is likely further down the line or a vent issue, which goes to a plumber with a powered machine.
