Why Hot Water is Coming From Your Cold Faucet

Why Hot Water is Coming From Your Cold Faucet

There are a number of minor plumbing issues that can be caused by a few different culprits, and a great example here is any issue where hot water is mistakenly coming out of a cold water tap. There could be a few reasons behind this, some that are simple and straightforward to remedy and others that may be a bit more involved. 

At Neighborly Plumbing & Services, we're happy to offer a wide range of plumbing solutions to clients around Salt Lake City, Millcreek, Sugar House, Park City and nearby areas, including for needs like water heaters and many others. Here are some of the possible reasons why you might be noticing hot water out of the cold water faucet, plus what can be done about it - either on your own if you're comfortable or with the help of our team if needed. 

Pipes Too Close Together

In some cases, pipe location is to blame for hot water coming out of cold faucets. If your pipes are too close together, the hot and cold pipes can become intertwined, sending hot water through the cold lines. 

This is a classic case for why any plumbing work should be done by an experienced professional who knows how to properly install and configure pipe systems. Re-configuring pipes is a job typically too complex for DIYers, but one our team of plumbing experts can complete in short order. 

Pressure Concerns

If your hot water pressure has become too high, either in the water heater or a specific faucet, there may be too much hot water flowing into the cold water lines, leading to hot water even in the cold faucets. This can be an issue with older tanks that need to be replaced or if you've recently added a new appliance like a dishwasher, which may require additional plumbing work and/or system reconfiguration. 

In some cases, a quick adjustment of a given faucet's pressure will solve the issue. However, if the problem persists, you may need to consider a full water heater replacement or call in our team of experts to assess and re-configure your plumbing system. 

Thermostat Issues

When we talk about a thermostat in this setting, we don't mean your home's HVAC thermostat, but rather your water heater's thermostat. If the settings are out of whack or there is damage to the device, your hot water may be a bit too hot, leading to it flowing through cold faucets as well. 

In this case, if you're comfortable and experienced enough with plumbing work, you can try adjusting the thermostat yourself. Otherwise, our team here at Neighborly Plumbing & Services can take care of it for you. 

Damaged Operational Valves

Operational valves are important components of water expansion tanks, providing on-demand limiting of water pressure to avoid damage to other fixtures. If these are damaged, hot water can flow through the cold lines. Again, we recommend calling in our team for such an issue, as it needs to be done correctly and without risking further damage. 

Improper Heat Trap Installation

Another possible culprit for hot water coming out of cold faucets can be an improperly installed heat trap. This device is important for preventing heat flow from the tank to other parts of the system, and if it's not done correctly, you may find yourself with hot water coming out of your cold taps. 

The installation of a heat trap requires careful work and precision, so unless you're an experienced plumber, this is also one job we'd recommend our experts for. 

Problems With Your Faucet Cartridge

Most faucets today utilize a cartridge to control the flow and temperature of water, so if there is an issue with the component itself - from damage to misalignment - it can lead to hot water coming out of a cold faucet. This is another job that requires precision to do correctly, so if you find yourself in this situation, we'd recommend giving us a call first thing to get the issue quickly resolved.
