If you're suddenly faced with a kitchen sink mixer tap that has no hot water, it can be quite frustrating. This essential fixture in your kitchen is responsible for providing both hot and cold water, so when one of those options is no longer functioning, it can make daily tasks like washing dishes and preparing meals much more difficult. But fear not, there are several simple solutions to get your kitchen sink mixer tap back up and running with hot water in no time.How to Fix a Kitchen Sink Mixer Tap That Has No Hot Water
The first step in fixing a kitchen sink mixer tap with no hot water is to determine the cause of the issue. There are several potential reasons why your tap may not be producing hot water, such as a faulty cartridge, temperature limiter, or clogged aerator. By troubleshooting the problem, you can pinpoint the exact issue and find the appropriate solution.How to Troubleshoot a Kitchen Sink Mixer Tap with No Hot Water
One of the most common causes of a kitchen sink mixer tap with no hot water is a faulty cartridge. The cartridge is responsible for regulating the flow of hot and cold water, and if it becomes worn or damaged, it can lead to a lack of hot water. Another common culprit is the temperature limiter, which is a small device that controls the maximum temperature of the water coming out of the tap. If this is set too low, it can prevent hot water from flowing. Lastly, a clogged aerator can also be to blame for a lack of hot water. Over time, mineral deposits and debris can build up in the aerator, inhibiting the flow of hot water.Common Causes of a Kitchen Sink Mixer Tap with No Hot Water
If the cartridge in your kitchen sink mixer tap is the culprit for the lack of hot water, it will need to be replaced. To do this, turn off the water supply to the tap and then disassemble the tap to access the cartridge. Take note of the make and model of your tap, as well as the type of cartridge it uses, to ensure you purchase the correct replacement. Once installed, turn the water supply back on and test the tap for hot water.Replacing the Cartridge in a Kitchen Sink Mixer Tap to Restore Hot Water
If the temperature limiter is to blame for the lack of hot water, it can usually be easily adjusted. Look for a small screw or knob on the tap and use a screwdriver or pliers to turn it counterclockwise. This will increase the maximum temperature and should allow hot water to flow again. If you're unsure of where to find the temperature limiter on your tap, consult the manufacturer's instructions or contact a professional plumber for assistance.Adjusting the Temperature Limiter on a Kitchen Sink Mixer Tap for Hot Water
If the aerator is clogged, it can easily be cleaned to restore hot water flow. To do this, unscrew the aerator from the tap and soak it in a mixture of equal parts water and vinegar for about an hour. This will help dissolve any mineral deposits or debris. After soaking, rinse the aerator and screw it back onto the tap. Turn on the hot water and check to see if the issue has been resolved.Cleaning the Aerator on a Kitchen Sink Mixer Tap to Fix No Hot Water
In some cases, the issue may not actually be with the kitchen sink mixer tap, but rather with the water heater. If you have a tankless water heater, it may need to be flushed to remove any mineral buildup that could be affecting the flow of hot water. If you have a traditional water heater with a tank, check to make sure the pilot light is lit and the temperature is set high enough to produce hot water. If you're unsure of how to check or perform maintenance on your water heater, it's best to contact a professional plumber for assistance.Checking the Water Heater for Issues with a Kitchen Sink Mixer Tap with No Hot Water
