My Shower Is Not Getting Hot But There Is Hot Water Whats The Problem

If your shower isn’t getting hot but other fixtures in your home have hot water, the issue likely lies within the shower valve or mixing components rather than your water heater. One common culprit is a faulty thermostatic mixing valve (TMV) or pressure-balancing cartridge, which regulates the mix of hot and cold water in your shower.

Over time, these valves can wear out, become clogged with mineral deposits, or get stuck, preventing the proper flow of hot water. This is especially common in homes with hard water.

Another possible issue is a misadjusted anti-scald device, a safety feature inside the shower handle that limits how hot the water can get. If set too low or out of alignment, it can block hot water flow entirely.

In rare cases, incorrect plumbing connections or cross-flow between hot and cold lines can also affect shower temperature, especially in older or remodeled homes.
