Is my shower high or low pressure?

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.

Will a pump increase shower pressure?





Install a shower pump

A shower pump is a small mechanical device that is fitted to your home water system. Installing a shower pump is an easy and effective way to increase the water pressure in your shower.

Will low water pressure affect my electric shower?

In some cases, yes. However, the majority of modern electric shower systems are designed for use with a cold mains system with low water pressure.

Why is my electric shower not powerful?

The most common cause of low shower pressure is a blocked showerhead, as a result of limescale build-up. These blockages obstruct the water flow, leading to reduced pressure over time. Most showers are fitted with a filter, protecting the pipework from debris, but this can become partially blocked by scale.

What is the best flow rate for a shower?





Also known as “flow rate”, GPM is a measure of how many gallons of water flow out of your shower head each minute. Since 1992, a maximum of 2.5 GPM is the federally mandated flow rate for new shower heads. This means no more than 2.5 gallons of water should flow out each minute.

What’s the difference between gravity fed and pumped?

Gravity fed soft serve machines use gravity to feed the product mix into the cylinder while pump fed machines use pressurized pumps to push mix inside the freezing cylinders.

What water pressure does an electric shower need?

1 bar

How much mains water pressure is needed to operate an electric shower? A minimum running pressure of 1 bar is required at the mains entry to successfully operate an electric shower system. The water flow rate must be 8 litres per minute, and the maximum static pressure should not exceed 10 bars.

What makes a shower powerful?



The higher the wattage the more powerful the shower, but also the more expensive. If you chose an economy model, your electric shower might feel as if the water is low pressure. If you suddenly experience low pressure, then it might be a plumbing issue or leak somewhere in the shower system.

How do I increase the water pressure in my gravity fed shower?

If you wish to keep your gravity fed system and want a bath shower mixer or shower valve then your only option is to add a booster pump to your water system, thereby providing suitable water pressure to run a choice of stylish shower valves.

What pressure is gravity-fed water?

around 0.1 Bar



Gravity Fed Heating Systems
As the name suggests, the pressure supplied around your household is based upon the height in which the cold storage tank sits from the location of the taps around your house. So in gravity systems, every 1 metre drop from the water tank typically equates to around 0.1 Bar in pressure.

What type of shower do I need for a gravity-fed system?

Low pressure showers

They are also known as vented systems. The benefits of a gravity system are that they are compatible with any shower in our range, including mixer, digital, electric and power showers. This is the only system suitable for a power shower.

Can I fit a pump to a gravity-fed shower?

Conventional Gravity Fed System



A gravity fed system will consist of a large cold water storage tank in the roof or loft and a hot water cylinder in an airing cupboard. If you have a conventional gravity fed system, you will be able to fit a shower pump.

What is a gravity-fed power shower?

A gravity-fed water system usually provides low water pressure, depending on the distance from the bottom of the cold tank to the shower head. The greater the distance, the better the pressure. To give a higher pressure from a mixer shower, a booster pump can be installed.

How long can you run a shower pump?

A pump will either run continuously or it needs to rest after about 10-15 minutes of use (for about 45 minutes to cool down).

Do you need a pump with a thermostatic shower?

If the flow is equal between the hot and cold, you should be able to install a shower. If – as in most cases with an unvented system – the hot flow is much lower than the cold, then you’ll most likely need a shower pump.

Do I need a positive or negative shower pump?



If the shower is more than 600mm, about two rulers, below the cold water tank, then you need a positive head shower pump. If the shower is less than 600mm below the cold water tank, then you need a negative head shower pump.

What is the difference between an electric shower and a thermostatic electric shower?

A combination of water pressure and temperature allows a thermostatic shower to function. Unlike a thermostatic shower, electric showers have their own heating element – which is usually seen in a box on the wall – so they only need a cold water supply, whereas thermostatic showers need hot and cold water.
