Common Plumbing Issues and Solutions – Tabelle

Issue Solution
Clog in Drain Pipe
  1. Use a plunger to try and clear the clog. Place the plunger over the drain, ensuring a tight seal, and push and pull vigorously to create suction. Repeat several times if necessary.
  2. If the plunger doesn’t work, use a plumber’s snake (also known as a drain auger) to remove the clog. Insert the snake into the drain until you feel resistance, then crank the handle clockwise to break through the clog. Withdraw the snake and repeat if needed.
  3. If the clog persists, call a professional plumber. They have specialized tools and expertise to remove stubborn clogs.
Leaking Drain
  1. Tighten the connection between the drain pipe and the sink using a wrench. Check for any loose nuts or fittings and tighten them to stop the leak.
  2. If tightening doesn’t work, replace the rubber gasket or washer. Turn off the water supply, unscrew the drain pipe, remove the old gasket or washer, and replace it with a new one. Reassemble the drain pipe and check for leaks.
  3. If the leak continues, call a professional plumber. They can identify the source of the leak and repair or replace any damaged parts.
Low Water Pressure
  1. Check if the aerator is clogged and clean or replace it if necessary. Unscrew the aerator from the faucet spout, rinse it with water, and use a toothbrush or small brush to remove any debris. If the aerator is damaged, replace it with a new one.
  2. Ensure that the shut-off valves are fully open. Locate the shut-off valves under the sink and turn them counterclockwise to ensure they are fully open. This allows maximum water flow to the faucet.
  3. If the problem persists, check for any leaks or blockages in the supply lines. Inspect the supply lines for any visible leaks or kinks. If necessary, replace the supply lines or call a professional plumber to address any hidden issues.
  4. If necessary, call a professional plumber. They can diagnose and resolve any underlying issues causing low water pressure.
Foul Odor
  1. Clean the sink using a mixture of baking soda and vinegar. Sprinkle baking soda over the sink surface, including the drain, and pour vinegar over it. Let the mixture fizz for a few minutes, then scrub the sink with a brush or sponge. Rinse thoroughly with water.
  2. Pour boiling water down the drains to remove any buildup or bacteria. Boil water in a kettle or pot, carefully pour it down the drains, and repeat if necessary. This helps to flush out any organic matter causing the odor.
  3. Use an enzyme-based drain cleaner to eliminate any organic matter causing the odor. Follow the instructions on the cleaner’s packaging, pour it into the drain, and allow it to sit for the recommended time. Flush the drain with water afterward.
  4. If the odor persists, call a professional plumber. They can inspect the plumbing system to identify and eliminate any underlying issues causing the foul odor.
Loose Faucet Handle
  1. Tighten the screw or nut securing the handle using a screwdriver or wrench. Locate the screw or nut on the handle and tighten it clockwise until the handle feels secure.
  2. If tightening doesn’t work, replace the handle or cartridge. Remove the handle by unscrewing the set screw or nut and replace it with a new one. If the issue is with the cartridge, follow the manufacturer’s instructions to replace it.
  3. If the issue persists, call a professional plumber. They can assess the faucet and handle mechanism to determine the cause of the problem and make necessary repairs.

Understanding the functionality of these components is pivotal for troubleshooting and maintenance. By familiarizing yourself with their roles, you can promptly identify any issues that arise and take appropriate measures to address them.

FAQ

How are double sinks plumbed?

In single sink plumbing, there is only one basin with its own tailpiece connected to a sanitary tee, which is then connected to the P-trap drain. On the other hand, double sink plumbing has two basins, each with its own individual tailpiece connected to separate sanitary tees, which are then connected to the P-trap drain. Another option for double sink plumbing is using a swing tee trap. This alternative method allows for effective drainage in both basins.

Does a double kitchen sink need two P traps?

It’s unlikely that enough water would “backflow” into the first trap when the second sink is draining. Although it may seem like a possible scenario, it’s not something you can rely on. Having just one trap on a double sink is a safer option, as it eliminates the remote possibility of backflow.

Can two sinks share a drain?

To solve the issue, you should replace the current sanitary tee inside the wall with a double sanitary tee. Double sanitary tees are commonly used to connect bathrooms, allowing for sinks on both sides of the wall while utilizing the same stack.

Do you need two water lines for a double sink?

Each sink requires its own water pipe. If you do not have enough water pipes for all your sinks, it is recommended that you reach out to a professional plumbing service for assistance.
