When you turn on the shower, all you get is hot water. There might be several reasons for this. Here, we’ll quickly review the most common frequent reasons for this issue.

Pressure Balancing Valves Issues

The primary function of a pressure-balancing valve is to prevent sudden changes in water temperature caused by variations in water pressure. It accomplishes this by balancing the flow of hot and cold water to maintain a stable mix, regardless of changes in the pressure of either water supply.

Your pressure-balancing valve could be faulty for starters. It can result from corrosion, mineral buildup, a broken cartridge, or a damaged valve. If this valve goes bad your shower can suddenly stop supplying cold water, and constantly only hot water coming out of your shower. Replacing the faulty valve can solve this problem.

Water Heater Issues

If your shower is connected to a hot water heater, there may be a problem with the heater that is affecting the cold water supply. For example, if the heater is malfunctioning, it may not be sending cold water to the shower. Check the water heater for any visible issues or consult a professional to assess and address the problem.

Plumbing Issues

Cold water can be difficult to obtain. A shower may not produce cold water if the pipe that delivers it is blocked. Clogged pipes, broken valves, or water mains can cause this problem.

However, you should be aware that this rarely happens and is more likely to happen when there is construction adjacent or there is a problem with the local or municipal water supply.

If the problem is with the cold-water supply in the residence, there will be hot water only. On the other hand, a blockage in the cold-water line for a shower is very unusual because debris can enter the pipe. If the cold-water line is blocked, the entire house will be without cold water.

Damage Shower Valve

In some cases, the problem may be the shower valve itself. If the shower valve is broken or clogged, the hot and cold water may not mix properly, resulting in a hot shower.

Internal shower valves components, such as the cartridge or mixer, can become damaged, worn, or blocked, preventing cold water from flowing properly. In such cases, you may need to replace the faulty valve or its components. Consider contacting a plumber or manufacturer for assistance.
