Is Your Cold Water Too Hot?

When you are getting warm or hot water from your cold faucets, it could be something minor, or it could be a real problem. For this reason, you cannot gamble with time. Always have this issue addressed right away, starting with learning the possible causes behind it. There could be a wide range of culprits causing your cold water to run warm, but the most common include too much water pressure, closeness of pipes, recirculating plumbing, improper installation of heat traps, water expansion tank valves, and even something known as the heating effect.

Here are some details to help you better understand and detect these possible cold water-hot water causes:

🢚 High Water Pressure

High water pressure is a great thing, when it is the right amount of pressure. When water pressure is too high, it can begin to cause problems throughout the rest of the home’s plumbing. One such problem is cold water running hot.

🢚 Water Expansion Tank Valves

If you have a water expansion tank installed, it will require a one-way valve or pressure lowering valve on the water meter, otherwise, hot water will flow into your cold water tap. Another possibility is that the thermostat in the immersion heater has gone defective, causing any stored water in the water heater to boil over into the cold water lines.

🢚 Poor Heat Trap Install

When your plumbing pipes and systems are being installed, your contractors must ensure that heat trap is placed in the water heating inlet. Otherwise, hot water stored inside a water heater will flow out and integrate with the cold water lines.

🢚 The “Heating” Effect

Near your faucets are copper lines, which can heat up from hot water usage. When this happens, the heat can transfer, and make the fixtures and cold water very hot. This heating effect is temporary, however, and will cool once all the cold water has flowed through the lines.

🢚 Recirculating Plumbing

If your home is constructed with hot water recirculating plumbing, it could be the root cause of your cold water tap running hot. You will continue to get warm water from the cold water tap until the heated water makes it to the temperature valve that regulated re-circulation.

🢚 Pipe Vicinity

Hot water plumbing pipes that are too close to the cold water plumbing pipes are known to cause the cold water-hot water issue. Over a period of time, this heats up the cold water pipes, which warms up the water that flows through them. This result is increased if a water heater is nearby.
