Why is the Kitchen Sink Not Getting Hot Water?

Home maintenance issues aren’t always straightforward. Some may require significant repairs, and some only need a simple, DIY fix. The lack of hot water in your kitchen sink is the same. This issue could be caused by complications such as a blocked faucet or a water heater that needs servicing.

On the other hand, it could need a simple solution such as turning the water valve under the sink back on and figuring out which of these solutions your kitchen sink needs isn’t difficult. Let’s troubleshoot the reasons why your kitchen sink isn’t getting hot water.

Reasons Kitchen Sink is not Getting Hot Water

As we mentioned earlier, there could be various reasons why you aren’t getting hot water in your kitchen sink. You could be having a blockage in the faucet, an issue with the water heater, or a faulty faucet cartridge. You should examine each part until you find the exact cause of the issue with your kitchen sink. Let’s look at some of them.

Line Blockages

Blockages in the water lines could be preventing hot water from getting to your kitchen sink. To check whether or not you have line blockages, get under the sink and turn off the cold water supply. Next, you should loosen the cartridge and turn the hot water on. If you still don’t get hot water after this, there could be a blockage in your kitchen faucet.

To fix this:

• Get under the sink and turn off the hot water supply.
• Take out the hot water supply line and place an empty bucket under the connection.
• Turn on the cold water.
• Block the faucet spigot with your finger and turn on the cold water.

This action will force the water to pass through the hot water inlet and force anything causing the blockage to get out of the faucet. Hot water should flow again once you remove the blockage and reassemble your sink.

Water Heater Issues

Some common water issues preventing water from getting to your hot water faucet include:

• Failing heating elements and
• Leakages caused by rust and corrosion

Failing Heating elements

If there are failing elements inside your water heater, this could be the reason why you don’t have hot water in your kitchen sink. To check whether this is the problem:

• Shut off the electrical and water supply to your water heater. Remove heating elements by following the instructions on your unit.
• Check if any elements are corroded or have rust and other damage that may hinder them from working. Order new ones if they’re damaged.

Leakages Caused by Rust and Corrosion

Rust and corrosion can cause leaks. If there are signs of leakages caused by these two aspects, you will have to buy a new heater. Check where the leak is coming from so you can determine its cause. Other than corrosion and rust, other problems causing leakages include:

• Loose pipe connections
• A leaking inlet valve or gasket
• Excessive pressure in the pressure and temperature valves

These issues can be fixed, and once they are, you should get your hot water with no problem.

Cartridge Issues

There is a cartridge installed inside your single-action kitchen faucet if that’s what you have. The cartridge controls the amount of cold and hot water that comes on depending on how you turn the faucet.

The cartridge tends to collect debris that causes blockages over time. The blockage prevents hot water from getting to the faucet. To repair this issue, the cartridge must be removed from the faucet and cleaned. How to clean the cartridge will depend on the type you have.

Kitchen Sink Takes a Long Time to Get Hot

Here are some reasons why your kitchen sink takes a long time to get hot.

• There’s already water in the pipes: when you turn your faucet on, water will start to come out. However, this is water that is already in your pipes. You won’t get water directly from the heater since there was already water in your pipes.
• Distance from the faucet to the water heater: hot water has to travel from your water heater to your faucet. The water has to get through multiple pipework before it can get to your fixture. But, as it does this, the cold water will flow first.
• Volume restrictors: some fixtures have a volume/flow restrictor installed. These allow you to save on costs and conserve water. However, since the water comes through slowly, hot water will take longer to get to you.
• Malfunctioning water heater: your water heater could have a malfunction if it’s taking too long to heat water or the hot water gets finished too fast. Call a professional to have a look at it if you think it’s nearing the end of its lifespan.
• Sediment buildup: water flowing through your home usually has minerals such as magnesium and calcium in it. If you have hard water, you are more susceptible to mineral buildup, which reduces the amount of water your tank can hold. If the tank has reduced capacity, it will run out of hot water fast.
• Outside temperature: if it’s cold outside with freezing temperatures, your heater will work harder to deliver hot water since the pipes outside that are in cold ground will cool the water.
• Thickness and size of the pipes: if your pipes have a larger diameter, they’ll take longer to deliver water since they hold much more. The opposite will happen if they’re smaller.

Can You Speed Up Time it Takes to Get Hot Water?

Yes, you can. But, there are several things you must do to achieve a faster rate of hot water. Here’s how:

• Pipe insulation: adding insulation to your pipes can solve the problem, especially if they’re a wider diameter or temperatures are freezing. Insulation will keep the heat in for much longer.
• Hot water recirculation pump: this system will allow unused water to circulate back to the heater. This reduces your wait time and ensures there’s hot water in other areas of your home.
• Install higher flow rate fixtures: if your kitchen faucet has a low flow rate, replace it with one with a higher flow rate.
• Upgrade to tankless water heater: such heaters don’t have a tank to store water. They heat water through the system as it flows.
• Routine maintenance: regular maintenance of your water system can help you prevent hot water issues.

How Long Should it Take to Get Hot Water to Kitchen Sink?

The correct answer for this question is that it’s dependable. The amount of time hot water should take to get to your kitchen sink depends on:

• The distance of the faucet from the water heater.
• The diameter of your pipes
• External temperatures.
