Plumbing Tips Everyone Should Know

Everyone knows how frustrating water and sink issues can be. It can be worse when you probably want to do some oily and messy dishes, and the kitchen sink isn’t receiving any hot water. 

There are several reasons your kitchen sink is out of hot water. After understanding the root cause, you will be better positioned to devise a solution and preventive measures.

Although some hot water issues are self-manageable, you might need to call a professional plumber for the more complex ones to avoid messing up the system. We are just a phone call away for all your plumbing needs.

Let’s discover eight reasons why there’s no hot water in your kitchen sink. 

Plumbing Tips Everyone Should Know 1

A Faulty Cartridge

The cartridge is located at the faucets to control the quantity and speed of water passing through them. In hot and cold water systems, the cartridge allows passage of both temperatures, as required and operated by the user. There’s no water in your kitchen sink because the cartridge might be experiencing some defects. 

Like any other part of the sink, the cartridge is prone to breakages, blockages, and mineral build-up, preventing it from functioning correctly. A faulty cartridge might not allow a smooth exchange of hot and cold water to the sink. 

Mineral Build-Up Across the Faucets

Another reason your sink is not receiving hot water could be the presence of mineral build-up across the faucets. Faucets are prone to mineral deposits resulting from hard water usage over many years. 

These deposits collect across various parts of the taps and might lead to blockages or improper functioning of the system. Mineral build-up can get worse with time if not managed. 

A Faulty Heating Element 

Like any other artificial equipment, the water heating element is prone to damage, faults, and breakdowns. There’s no hot water in your kitchen sink because the heating element might be experiencing any of the above issues. 

Due to its complexity, problems relating to water heating elements might require you to seek a professional’s help rather than doing it yourself. Regular maintenance of the water heating element can also help reduce the chances of breakdowns. 

Blocked Water Line

A blockage in the water lines prevents water from flowing through them smoothly. The reason your kitchen sink isn’t receiving hot water could be the presence of blockages in the line that transports hot water.

Water lines can be blocked by mineral deposits, debris build-up, and frozen water crystals (especially during winter).

You can check for blockages across the water lines by turning off the water to unscrew the cartridge. Check for any obstruction across the cartridge by cleaning and screwing it back to test its functionality. 

Prevailing Leaks

Le leaks significantly affect the intensity of hot water flowing into the sinks. If not managed, the leaks can result in no hot water in the sink. A leaking pipe can interfere with the flow of hot water, mainly if it’s located close to the water heating element. 

There are several temporary leaking solutions, such as using rubber tapes and applying epoxy putty while working for more permanent techniques. 

A Faulty Shutoff Valve

A shutoff valve is a solid component located within the main water inlet, which is opened or closed to control water flow into the house. Sometimes, your sink is not receiving hot water because of a faulty valve. 

Closing the shutoff valve partially can result in low water pressure, affecting the level of hot water flowing into the sinks. You might need to protect the primary water supply system from damage and unauthorized operation if you have kids and pets. 

General Water Pressure Issues

Since the cold water lines are connected directly from the main water supply, they are not significantly affected by water pressure issues like their hot water counterparts. When the entire house is experiencing low water pressure, the hot water lines are more hit, preventing hot water entry into the kitchen sinks. 

To tackle common water pressure issues in the house, check the water level in the primary source or install a pressure booster. 

Large-Sized Pipes

Did you know that the size of the pipes can affect the flow of water into the sinks? If your lines are extra-large, hot water will take longer to reach the kitchen sink since the pipes hold more cold water. 

For instance, when you turn on the hot water taps, you will receive cold water for a while before the hot water flows out. You can solve the issue by installing smaller pipes.
