Depending on your current flow rate, you may be able to increase the flow simply by removing the filter or restricting device or replacing the shower head with a higher-flow model, such as increasing to a standard 2.5 gpm head. Before you change the shower head, make sure that the new model is legal in your area.
If you just experience a (dramatic) increase in pressure it is very likely that you flow regulator stopped working correctly. Maybe it broke, became unscrewed, or whatever. To stop the flow you would need to find a replacement regulator (probably from manufacturer) or just get a new shower head.
If the problem is not related to your plumbing, a relatively inexpensive option you can try is to buy a special shower head for low water pressure. These are shower heads that are designed specifically to help increase water flow in areas with pressure issues.
A high pressure shower head maximizes the flow of water through the shower head for a powerful spray. Waterpik® shower head engineers design water passages to minimize flow restriction and optimize the shower force, and put every shower head design through more than 1,000 hours of testing.
The Reason. The explanation for this is the spray head being too close to the water level in the cold water storage tank. If your home suffers from low water pressure, a standard shower valve is often not enough to provide a powerful and invigorating flow of water.
30 meters/100 feet/3 bar: General water resistant watches can withstand minor moisture from splashing, but should not be worn for swimming, diving, bathing, or showering.
Water pressure is measured in 'bar', and generally speaking anything 0.3 bar or below requires a low water pressure tap or shower, and anything at 1.0 bar or above requires a high water pressure tap or shower.
Water systems which operate at 1.0 bar pressure (10 m of drop) or greater are considered high pressure systems. Those with a pressure less than 1.0 bar are considered low pressure. When you're ready to choose a tap or shower, you'll find the water pressure it's suitable for will be clearly labelled.
First, shut off the water at your house's internal water main. Turn the shut off valve completely to the right. Loosen the the locking nut on the water pressure regulator by turning it to the left. Turn the adjusting screw to the left to reduce the water pressure or to the right to increase the water pressure.

A 10.8kw electric shower is the most powerful electric shower there is and it means that it will provide improved pressure and a higher water temperature. For the best performance, 10.8KW electric showers need a minimum of 1.5 bar water pressure with a flow rate of 11 litres a minute.
A high flow shower hose which has an internal diameter of at least 10mm will deliver more water with very little pressure loss compared with a small bore shower hose (typically 8mm).
Water pressure is a measure of the force of the water moving through your pipes. Water pressure is measured in bars, with 1 bar being the force needed to raise water to a height of 10 metres. Each tap or shower will be rated with a minimum required pressure rating, typically between 0.1 and 3 bar.
Pressure is higher at night, when fewer people are using water. If your pressure reads over 80 PSI, you need to take action to protect your plumbing system.
On average, the water pressure in a home should not be more than 80 psi. When water pressure reaches over 80 psi, signs of trouble may start to occur. High water pressure can be caused by: A local water company keeping water pressure high for tall buildings and fire hydrants in the area.
High water pressure shortens the life cycle of your appliances and damages your plumbing fixtures, leading to leaks and pipe bursts. Not only that, but excessive water waste is bad for the environment and may cost you more than you think.
Test your Water Pressure
- Hook up the pressure gauge to an outside water spigot.
- Turn on the water.
- Read the instant reading. Make sure the shutoff valves near the water meter are fully open. If the reading is low, the city may be delivering water at a low pressure (less than 40 psi)
- A reading of 45 to 55 psi is ideal.
Your plumber is right; anything above 80 psi (pounds per square inch) is too high and in fact requires a pressure-reducing valve under code. But 95 psi is not exceptionally high, and I can tell you millions of homes have had water pressure above the recommended mark for decades, suffering no ill effects.
Standard Water PressureThe incoming water pressure should never be over 75 psi. Larger homes require a higher incoming pressure rating than small homes, as water will slow down slightly each time it encounters a bend in the pipes.
Water suppliers' statutory service standard level of mains water pressure is 10 metres/head (or one bar). This means there is enough force/pressure to push the water to a height of 10m. Another way of putting it is enough water pressure to fill a cold water storage cistern in a two storey house roofspace.
Usually it's installed in one of two places, buried in the ground on the main water line either near the area the water line goes into your home or at the water meter. But again, because there is no standard, the valve can be anywhere buried under the ground on the line.
