With water pressures across the country being…let’s say temperamental...at best, it’s essential that you choose the right showering products to complement your home’s system.

If you’re a longtime sufferer of pressure problems, you’ll be thrilled to find out that even homes with substandard flow rates can be made more effective if you choose wisely.

To help out, we’ve put together this quick ‘how-to’ guide to help you figure out which system your home has, as well as recommend specific products to complement it.

How to Identify Your Water System

Before you even consider choosing a shower, the most important thing you must do is find out what kind of water system your home uses. This, in turn, will help you figure out if the shower you are currently using is ill-suited to your situation.

In UK homes, there are four common types of plumbing systems; combination, gravity-fed, pump assisted, and mains high pressure. We’ve listed their key features below, with diagrams to help you determine which system you have in your own home:

Gravity Fed Systems

Gravity fed systems are commonly found in older homes and are likely to provide low water pressure.
  • Hot water is provided by a large hot water cylinder in your home.
  • No shower pump will be installed.
  • Your home will likely have low pressure of around 0.2Bar.

Combination Boiler Systems

Combination boilers heat water directly from the mains, providing hot water on demand and powering your home's central heating.
  • A combination boiler provides your home with hot water on demand.
  • Your home won’t have any storage tanks.
  • No shower pump will be installed.
  • Your home should have medium pressure, between 1Bar and 5Bar.

Pump Assisted Systems

Pump assisted water systems make use of a booster pump to make showers more exhilarating.
  • Simply put, these are gravity fed systems with a booster pump installed.
  • If you listen carefully, you may be able to hear your shower pump when your shower is in use.
  • Booster pumps are available in “Positive Head”, “Negative Head” and “Universal Head” models.
  • Positive Head pumps are suitable for most situations in which your shower is positioned below your cold water storage tank.
  • Negative Head pumps are for situations in which your shower is positioned above the cold water storage tank (i.e. for loft conversions).
  • Universal Head pumps work in both of the conditions mentioned above.
  • A pump assisted system is likely to provide high water pressure, from 1.5Bar to 3Bar plus.

Mains High Pressure Systems

You’re unlikely to experience poor pressure if you’re lucky enough to have a mains high pressure system.
  • With a mains high pressure system, your home won’t have a cold water storage tank in the loft.
  • Your home will have stored hot water (usually in a large cylinder in an airing cupboard), and a small kitchen cupboard sized boiler.
  • If your home uses a mains high pressure system, expect pressures of between 1.5Bar and 3Bar.
