Kitchen Tap Runs When Toilet Flushed
If you've noticed that your kitchen tap runs when the toilet is flushed, it could be down to a few different reasons. Let's explore some possible causes:
- Water Pressure Imbalance: This is the most common cause of such a phenomenon. When the toilet is flushed, a large amount of water is suddenly drawn from your home's main water supply. If your plumbing system isn't correctly balanced, this can cause a temporary drop in water pressure elsewhere in the house, resulting in your tap starting to run. Once the toilet cistern is refilled, the pressure should stabilise again.
- Faulty Fill Valve: If the fill valve in your toilet cistern is faulty or worn out, it could cause the water to run continuously, resulting in pressure changes within your home's water supply system. This change in pressure could be the reason why your tap runs when the toilet is flushed.
- Cross-Connection: A cross-connection is an inappropriate or unintended link between a potable water supply and a non-potable source. If there's a cross-connection between your toilet and kitchen tap supply lines, it could result in your tap running when the toilet is flushed. However, this is not a common occurrence and is generally against plumbing regulations.
- Pipe Size Issues: If your pipes aren't sized correctly, you may experience variations in water pressure when multiple water appliances are used simultaneously. For example, if your pipes are too small, they may not be able to handle the sudden demand for water when the toilet is flushed, resulting in your kitchen tap running.
- Faulty Plumbing Installation: If your plumbing was not installed correctly, there could be a series of problems, including incorrect pipe sizes, improper balancing, or issues with the toilet itself, all of which could lead to your tap running when the toilet is flushed.
- Old or Deteriorating Plumbing System: If your home's plumbing system is old or deteriorating, it may not be able to maintain stable water pressure when high-demand appliances like toilets are used. This could also be the reason for your kitchen tap running when the toilet is flushed.
Remember, diagnosing and repairing plumbing problems can often be complicated and should usually be left to a qualified professional.
If you're experiencing issues with your plumbing, it's always a good idea to get in touch with a plumber.

How to Fix a Kitchen Tap That Runs When the Toilet Flushed
If your kitchen tap starts running when the toilet is flushed, there could be several causes and corresponding solutions.
Here's how you might address each one:
- Water Pressure Imbalance: This might be a complex problem to solve as it involves the overall water system in your house. The best course of action is to call a professional plumber. They will be able to diagnose the issue and install a pressure balancing valve if needed to even out water distribution when high-demand appliances are used.
- Faulty Fill Valve: The fill valve inside your toilet cistern may need to be replaced. You can usually do this yourself by purchasing a new fill valve from a hardware store and following the instructions provided. However, if you're unsure, it's best to get a professional plumber to handle this.
- Cross-Connection: Cross-connections should be fixed immediately as they can pose a significant health risk, potentially allowing non-potable water to enter your drinking water supply. If you suspect a cross-connection, you should contact a professional plumber immediately.
- Pipe Size Issues: If the pipes in your home are too small, you may need to have them replaced with larger ones. This is a significant job and will require a professional plumber.
- Faulty Plumbing Installation: If the plumbing system was not installed correctly, a plumber might need to reconfigure or replace parts of the system. This could involve a variety of tasks, from resizing pipes to refitting valves, and should be done by a professional.
- Old or Deteriorating Plumbing System: An old or deteriorating plumbing system may need significant repairs or even complete replacement. A professional plumber will be able to assess the condition of your plumbing and recommend the best course of action.
Remember, whilst DIY solutions may seem like a good idea, if you're unsure about any aspect of plumbing repair, it's always best to call in a professional.
Not only will they be able to accurately diagnose the issue, but they can also ensure that any repairs are carried out safely and effectively.
