Why is there no flow or low flow rate with varying temperatures in my Bristan Plumbing Product?
- CCameron RodriguezJul 30, 2025
Several factors can cause this issue. Start by checking the showerhead, hose, and filters for any blockages and clean them if necessary. Ensure that the stop or service valve in the water supply pipework to the shower valve is fully open. If you have an instantaneous water heater, the flow rate or pressure may be too low, causing it to cycle on and off. If the water pressure is affected by other outlets, avoid using other water outlets while showering. Also, verify that the water pressure is sufficient. Additionally, airlocks or blockages in the pipework can cause these symptoms, so flush the pipework. Finally, confirm that both hot and cold water are reaching the shower valve, as the valve will shut down if either supply fails.
