Introduction
Welcome to our guide on how to fix hot water coming out of cold tap! If you’re experiencing this problem, you’re not alone. Many homeowners encounter this issue and find it frustrating, especially when it comes to daily activities such as washing dishes or taking a shower.
Before we dive into the solutions, let’s first understand why hot water is coming out of your cold tap in the first place. Typically, hot water and cold water are separated in your plumbing system with separate pipes. However, when hot water comes out of your cold tap, it suggests there is a cross-connection between the two pipes. This cross-connection may be due to various reasons, which we’ll explain in more detail below.
In this article, we’ll guide you through several methods to fix hot water coming out of cold tap, as well as the advantages and disadvantages of each. By the end of this guide, you’ll be equipped with the knowledge to solve this problem once and for all!
How to Fix Hot Water Coming Out of Cold Tap
Method 1: Check the Plumbing System
The first method to fix hot water coming out of your cold tap is to check the plumbing system. This involves examining the pipes and valves to identify where the cross-connection is happening.
Start by turning off the main water supply and draining all the taps in your home. Next, open the cold tap where hot water has been coming out and let it run for a while. If the water remains hot, it’s likely there’s a cross-connection somewhere near the hot water heater.
You can then check the valves and pipes near the hot water heater to see if there are any issues such as a faulty valve or a broken pipe. If you’re unsure, it’s best to call a professional plumber to help you identify and fix the problem.
Method 2: Install a Backflow Preventer
Another solution to fix hot water coming out of cold tap is to install a backflow preventer. This is a device that prevents hot water from flowing back into the cold water pipe.
Backflow preventers come in different types and sizes, so it’s essential to choose one that’s compatible with your plumbing system. You can either install it yourself or seek the help of a professional plumber.
One advantage of using a backflow preventer is that it’s a long-term solution that prevents hot water from entering the cold water pipe. However, it can be costly and time-consuming to install, especially if your plumbing system is complicated.
Method 3: Adjust the Anti-Scald Valve
The anti-scald valve is a safety feature that controls the temperature of hot water flowing out of the tap. If it’s malfunctioning, it could be the reason why hot water is coming out of your cold tap.
To fix this issue, locate the anti-scald valve, which is usually located behind the faucet handle. Use a wrench to turn the valve in a clockwise or counterclockwise direction, depending on the valve type. This adjusts the temperature of the water flowing out of the tap.
One advantage of adjusting the anti-scald valve is that it’s a simple and quick fix that doesn’t require any special tools. However, if you’re unsure how to do it, it’s best to seek the help of a professional plumber.
Method 4: Replace the Faucet
If all else fails, you may need to replace the faucet entirely. A faulty faucet can cause hot water to mix with cold water, resulting in hot water coming out of your cold tap.
To replace the faucet, turn off the main water supply and remove the old faucet with a wrench. Install the new faucet by following the manufacturer’s instructions.
One advantage of replacing the faucet is that it’s a permanent solution that ensures hot water doesn’t flow out of your cold tap. However, it can be costly and time-consuming, especially if you’re not familiar with plumbing work.
