Why the Shower Temperature Suddenly Changes
A widespread issue, especially in older homes, is shower temperature changing when other plumbing fixtures are used simultaneously.
A widespread issue, especially in older homes, is shower temperature changing when other plumbing fixtures are used simultaneously. This can be incredibly unpleasant, whether the water goes frigid or searing. However, this is not an issue that has to be endured; there are techniques plumbing companies can employ to lessen or even eliminate this issue.
Why this happens
Plumbing systems used to be installed differently in homes, but these methods have since improved, which is why sudden temperature changes in showers are more prevalent in older homes. Older homes typically have a plumbing system that’s made up of a trunk and branches. All the branches feed off the trunk, affecting the other lines when water is run. This affects not only the water temperature in plumbing fixtures but also the water pressure. When water is used in two fixtures simultaneously, the pressure decreases simply because it must be divided between two sources.
Update the pipe configuration
There are several ways to fix this problem, but the most efficient yet complicated option is to place the pipes in a different type of configuration. With a new configuration, each plumbing fixture can have its supply line instead of working off of just one trunk in the house. This is the most expensive solution, so it’s usually better suited for significant plumbing overhaul projects.
Manage water pressure and temperature
Increase water pressure
A simpler, more affordable option is to find a way to increase the water pressure. If the water pressure can be substantially increased, the effects of the temperature change and pressure should be less noticeable.
Add a mixing valve
Additionally, consider adding a mixing valve to the shower. This valve is designed to control the mix of hot and cold water that enters through the showerhead. Installing this evens the temperature before it exits the showerhead, helping ensure the water temperature does not jump to extremes.
Sudden changes in shower water temperature are often considered unavoidable; however, this does not have to be the case. No matter what happens in other parts of the home, every shower should remain comfortable. Professional HVAC companies can assist in implementing these solutions to ensure safe, balanced shower temperatures.
