Hopefully, you have not experienced a sudden cold shower just because someone came in and flushed the toilet in your bathroom.
But if you have - you know it's not an experience you would wish to repeat.
So, what causes this and what can you do about it?
The answer is typically old shower valves and/or poor plumbing.
Is It The Shower Valve?
A shower valve works in the following manner:
- Water pressure changes in the hot / cold water supply line
- This causes a piston to open or close a small port so that the water pressure remains balanced
- The balanced water pressure keeps the water flowing at the temperature you set
- If there's a problem with the shower valve and it's piston - then your water temperature will fluctuate
If your valve in the shower has worn out or is defective, when the water pressure in your water line changes due to a toilet being flushed, the water coming out of your shower head will fluctuate and get either colder or hotter.
Know that it doesn't have to necessarily or always be a result of the toilet flushing. Running the dishwasher or washing machine while you take a shower may do the same thing.
Fixing This Problem
We recommend to have a plumber come in and fix / replace your shower valve or possibly, install a thermostatic mixing valve to help regulate the water pressure and keep the temperature steady for you while you shower.
