Why Is There No Cold Water in Your Shower?

If your shower only produces hot water, the problem may involve the shower valve, cartridge, pressure balance device, plumbing line, or fixture setting. While it may seem unusual, this is a common issue that can often be repaired once the cause is identified.

Because shower water that is too hot can be unsafe, the problem should be addressed quickly.

A Faulty Shower Cartridge

Many showers use a cartridge inside the valve to control hot and cold water mixing. If the cartridge becomes worn, stuck, or clogged with mineral buildup, it may prevent cold water from mixing properly.

Replacing or repairing the cartridge may solve the problem.

Pressure Balance Valve Problems

Modern shower valves often include pressure balancing features to help prevent sudden temperature changes. If this part fails, it can affect water temperature and flow.

Cold Water Supply Issue

In some cases, the problem may be connected to the cold water line feeding the shower. A closed valve, blockage, or pressure issue could reduce or stop cold water flow.

Mineral Buildup

Hard water minerals can collect inside fixtures and valves over time. This may affect both water temperature and pressure.

Why You Should Call a Plumber

Shower valves can be difficult to diagnose without opening the fixture. A plumber can inspect the valve, identify the cause, and recommend the proper repair.
