What causes high water pressure from a showerhead?
1、The water pressure from the showerhead is too high, which may be due to excessive water pressure. In this case, an anti-jet valve can be installed to reduce the water pressure.
2. It could also be due to a malfunction in the showerhead, resulting in excessive water pressure and inability to adjust, in which case the showerhead should be replaced.
3. The high water pressure from the showerhead might be due to the adjustment valve being set to maximum outward water flow. This results in the showerhead spraying water forcefully outwards, creating a concentrated and rapid stream. To reduce the water flow, adjust the valve to ensure that all the outlets direct water outwards, which will reduce the water pressure.
How to handle excessive water pressure from a showerhead?
1. Install a pressure reducing valve at the main shut-off valve for the household water meter. If the household has a water meter flow adjustment switch, you can adjust the flow rate manually. Alternatively, these valves can be purchased at building material markets at reasonable prices, and installation can be arranged.
2. Utilize check valves and flow restrictors. These small components not only reduce water consumption and pressure, but also prevent backflow. After shutting off the water, they maintain the pressure within the shower head and balance it with the external atmospheric pressure, preventing dripping. According to one requirement of the National Standard GB18145-2014, both the handheld shower head and the overhead shower head must be equipped with check valves and flow restrictors, which are specified for water conservation and pressure reduction.
3. Replace the showerhead. Options include showerheads with air inlets, also known as air-in showerheads, and oxygen-enriched showerheads. These are generally more expensive than standard showerheads, but the price is acceptable to consumers. Most showerheads are made of ABS material, but ABS is not inherently inferior, nor is copper inherently superior. Current technologies are mature, and ABS is cost-effective and suitable for ordinary consumers.
4. If possible, a small-capacity valve can be used to control the water flow. This requires coordination between the distributor and the manufacturer.
