Why Is Hot Water Coming Out of the Cold Tap On My Sink?

There are many reasons why hot water occasionally comes out of your cold tap. Check out the top seven reasons below.

1. Location of Pipes

Your sink has two pipes, one that carries hot water and another that carries cold water. When these pipes run parallel to each other, the temperature of the hot water pipe can influence the temperature of the cold water pipe. You can fix the issue by correcting the pipe placement.

2. High Water Pressure

When the hot water pressure level of the tap gets too high, the hot water may be forced to exit the cold water tap.

3. Malfunctioning Thermostat

The immersion heater of your plumbing system has a thermostat that regulates water temperature. A malfunctioning thermostat can cause the immersion heater to overheat your water supply, resulting in hot water coming out of the hot water and cold water taps.

4. Copper Heating Effect

Copper piping is extremely conductive, meaning heat travels through it easily. As hot water passes through the copper pipes, it heats them. Cold water then passes through the warmed pipes, which causes lukewarm water to exit the cold tap.

5. Water Expansion Tank Valves

Water expansion tanks have an operational valve that lowers water pressure on demand. If hot water is coming out of your cold tap on your sink, this is a sign of a damaged operational valve. To prevent this issue, replace the operational valve if it’s malfunctioning or broken.

6. Incorrect Heat Trap Installation

Poor installation of the heat trap can cause warm and cold water to intermingle.

7. Faucet Cartridge Issues

Most sinks contain a cartridge that guides the flow of water. When this cartridge malfunctions or breaks, one of two things can happen. Warm water can travel through the cold water pipe in your home. In addition, this issue can cause your faucet to only pull water from the hot water pipe. A licensed plumber can help you fix a damaged faucet cartridge in your house.

4 Common Problems With Kitchen Sinks

As often as sinks are used in the home, issues are bound to arise from time to time

1. Clogged Drains

Everything from hair and toothpaste to food scraps and grease gets stuck in your sink and drains. This debris build-up not only puts a stench in the air but also slows the drainage process. First, try removing the clog manually. Use a drain plunger. The suction and compression can help loosen the clog. Place the plunger on the drain and push down.

When you pull the plunger up, it will pull water in the drain upward. This may begin loosening the clog. Push the plunger back down. Continue this process several times until the clog is loose. If this does not work, you will likely need a plumber. To prevent damage to your drain pipes, avoid using chemical drain cleaners.

2. Clogged Faucets

Hard water contains minerals that build up over time and impede water flow. Remove the tip of the faucet and clear the strainer of any debris or build-up.

3. Leaking Underneath

A leaky drain basket underneath your sink occurs when a bad pipe connection or improper sealing is present. Start by tightening the pipes, then install new ones if necessary.

4. Leaking From the Faucet

Make sure the water is turned all the way off. If the leaking persists, call your local plumber
