Why does hot water flow out of a cold water tap?
Pipe proximity is one cause of hot water flowing out of the cold water tap. When pipes run parallel and are seated too closely, heat can pass from the hot water side to the cold. This heats the water in the cold water lines, producing warm to lukewarm water. Cold water can also heat up by being too close to a water heater or forced-air heating duct.
Why is my hot water coming from the wrong tap?
They can range from pipes being too close together, a recirculating plumbing characteristic, or improper heat trap installation. It could also be affected by ventilation ducts, copper piping, too much water pressure, or thermostat woes.
What Is the “Copper Heating Effect”?
The proximity issue magnifies when copper is the plumbing material installed. Copper pipes are usually the most effective at retaining heat, which makes them the more desirable choice. The drawback of choosing copper is that any radiant heat transfer holds longer and warms up the cold water supply.
Is the Heat Trap Installed Properly?
These sections, called heat traps, allow cold water to flow into the water heater tank while preventing unwanted hot water. The heat traps ensure that the correct water temperature flows from its designated tap.
How Does the Water Expansion Tank Factor In?
Because water can’t compress, it needs some space inside the water heater to expand without building excess pressure. This is the function of the water expansion tank, usually a smaller tank installed on the water heater’s water supply. The air inside the expansion tank compresses, allowing the expanding heated water to flow into it and manage water pressure.
Why does my water heater run out?
Pinpointing why your hot water supply runs out can involve anything from power supply problems or various plumbing line errors. Most causes will lie in troubleshooting your water heater for possible solutions.
How does cold water heat up?
Cold water can also heat up by being too close to a water heater or forced-air heating duct. When the supply lines sit too closely to these heat sources, the radiant heat transfers to the cold-water pipes. This affects the water temperature flowing through the adjacent water lines though the effects are often temporary.

Is the sun heating up pipes?
You mentioned warm sunny days and I presume you're in the northern hemisphere. So the sun may be playing a direct role in heating up the pipes. You've noticed how surfaces that receive direct sunlight get a lot warmer (or downright hot, depending) than the surrounding air. The inside of a south-facing wall will be a lot warmer than the inside of a north-facing wall (in the northern hemisphere) when the sun is out in force.

Is a hot water pipe insulated?
It's likely that the pipes themselves are not insulated, especially since they are cold water pipes and there's less concern for losing energy (as there is when you're trying to conserve the energy you used to heat the water standing in your hot water pipes). So the pipes and the water resting in them will equalize at the temperature of their surroundings (air) fairly quickly.
