Sink and drain services in San Juan
A sink that drains slowly, leaks under the cabinet, or smells unpleasant can become a daily nuisance. While some problems start minor, an unattended clog or leak can damage connections, pipes, and nearby surfaces.
At Plumber of San Juan, we facilitate communication between residents, homeowners, property managers, and businesses that need help with sinks, faucets, drains, and sewer lines. You can request service for clogs, leaks, worn-out components, new installations, and replacements.
The goal is to identify the cause before recommending a solution. Not all clogged sinks require the same procedure, and a visible leak could originate from the faucet, drain, trap, or a supply connection.
Signs of problems in a sink
Some problems are obvious, like a sink full of water that won't drain. Others develop gradually and may go unnoticed until they affect bathroom use or cause dampness.
Among the most common signs are:
- Water slowly flowing down
- Sink completely covered
- Bubbling or gurgling sounds
- Bad smells coming from the drain
- Returning water
- Leaking under the sink
- Humidity inside the cabinet
- Faucets that keep dripping
- Rusty connections
- Recurrent plugs
When several drains show symptoms at the same time, the problem could be in a shared pipe. In that case, addressing only the sink drain will likely not resolve the underlying cause.
Repairing leaks under the sink
The space under the sink contains several parts that can develop leaks. Water could escape through the supply lines, valves, drain, trap, or fittings.
A small leak can cause damage if it continues for weeks and become an emergency if the volume of water increases. Constant moisture can deteriorate cabinets, produce odors, and spread to floors or walls. In apartments and condominiums, it could also affect areas below.
To locate the source of the leak, the connections are usually checked while the water is running and while the sink is draining. The solution may include tightening connections, replacing seals, changing a valve, repairing the trap, or replacing a damaged part.
Sink unclogging and drain cleaning
Bathroom sinks often accumulate hair, soap, toothpaste, personal product residue, and dirt. Over time, these materials can stick to the inside of the drain and restrict flow.
In kitchens and service areas, grease and food scraps can also cause blockages. That's why it's important to identify which line is affected and what materials might be causing the clog.
Depending on the location and severity of the blockage, the job may require cleaning the plug, disassembling the trap, or using tools to reach a deeper section. When the problem recurs frequently, it's advisable to check the condition of the line rather than simply temporarily opening it.

Problems with the siphon and connections
The trap is the curved section of pipe located under the sink. It holds a small amount of water that helps block odors from the drainage system.
This part can become clogged with debris, loosen, crack, or deteriorate due to corrosion. Signs of a problem include leaks inside the cabinet, foul odors, and slow drainage.
It's not always necessary to replace the entire assembly. In some cases, simply cleaning the trap, adjusting a joint, or changing a seal is enough. If the material is cracked or heavily corroded, replacing the part may be more practical.
Installation and replacement of sinks
You can also request assistance installing or replacing sinks in bathrooms, kitchens, offices, and commercial properties. The work may include connecting the faucet, water lines, drain, trap, and seals.
Before installing a new unit, it's advisable to confirm that the size, drain location, and faucet configuration are compatible with the space. The condition of existing valves and pipes should also be checked.
Replacement may be appropriate when the sink is cracked, loose, corroded, or no longer fits a remodel. Proper installation helps prevent leaks and alignment problems.
Why does a drain get clogged again?
A drain that clogs again shortly after being unclogged may indicate that some of the buildup remains in the line. There could also be a trapped object, a damaged pipe, or a blockage in a shared line.
Chemicals don't always eliminate the entire cause and can create hazards if mixed or left inside the pipe. If you used any cleaners before requesting service, inform the technician.
Check if other fixtures are producing bubbles, noises, or water backflow. These details help determine if the problem is limited to the sink or is part of a larger blockage.
How to care for sinks and drains
Avoid throwing hair, grease, food, or thick products down the drain.
Use a grid to catch debris.
Clean the plug and visible area regularly.
Don't ignore slow drainage or bad odors.
Check under the sink for moisture.
Do not mix unclogging chemicals.
Request an evaluation if the problem returns.
Close the valve if a connection is continuously releasing water.
Do not dismantle pipes if you cannot shut off the water supply or if strong chemicals have been used. A makeshift repair can worsen the leak or make subsequent work more difficult.
Frequently asked questions about sinks and drains
Why does my sink drain slowly?
Common causes include hair, soap, toothpaste, grease, or debris inside the drain plug, trap, or pipe. If several fixtures are draining slowly, there may be a deeper blockage.
Can a leak under the sink be repaired?
In many cases, yes. The repair depends on whether the water is coming from a connection, a valve, the trap, the drain, or a supply line.
When should I replace the sink?
This may be convenient if it is cracked, unstable, corroded, damaged around the drain, or if a remodel requires a different configuration.
Do you service commercial drains?
Service can be requested for offices, restaurants, shops, buildings, rental properties, and other commercial facilities in San Juan.
How much does it cost to unclog a sink?
The price depends on the location of the blockage, accessibility, the severity of the obstruction, and the tools required. The cost will be confirmed after assessing the problem.
