Everything You Never Knew You Needed to Know About Water Pressure


Water pressure might not sound like the most riveting of topics – but bear with us on this one. It might not have the glitz and glam of a high-end whirlpool bath or a fancy underwater lighting system, but if you’re a whirlpool bath or shower owner, you need to know about water pressure. But don’t worry, to save you from trawling the web for info, we’ve collected up all the essential stuff in today’s blog post. Let’s get started.

The fundamentals of bathroom water pressure

 If you’ve ever turned on a tap or shower only to be greeted by a weak drizzle of water rather than the expected torrent, you’re already aware of the effects of poor water pressure. Put simply, the term “water pressure” refers to the amount of force required to move water from the mains supply through your home’s pipework and out of the various outlets (taps, showers, and so on). This pressure is measured in units called “bars”, with one bar being the amount of force it takes to move water upwards ten metres.

Why water pressure matters in your bathroom 

Okay, so now we’ve covered exactly what water pressure is, it makes sense to also discuss exactly why it matters. One of the fundamentals of moving water around any building is that gravity matters. In a nutshell, this means that the more storeys a building has, the harder it will be for water to be delivered to higher rooms with equal pressure. When pressure is low, the result can be taps which lose a lot of their force – or, even worse, a shower which isn’t much more than a dribble. In addition, low water pressure can increase the amount of time it takes to fill your bath – and who would want that?

 How to troubleshoot low water pressure

 If you’re suffering from low water pressure in your bathroom, there are a few things you can do to identify the cause. From there, you can either resolve the issue if you’re able to, or speak with your local water authority to learn more about the causes. Here are some of the most common causes of low water pressure in the bathroom:

  • A room is simply too high up. If you live in a home with multiple storeys, your water supply will have a much tougher time reaching the bathroom if it’s on a higher floor. Even when it does, it may be weak due to the laws of gravity.
  • The geographical location of your home. All of our water is supplied from a local reservoir or similar reserve of water. The further your home is from this main supply, the weaker the flow could potentially be.
  • Local blockages in the system. If you’re lucky (relatively speaking), you may find that low water pressure is being caused by a blockage in your local system. If it’s only one tap with a low pressure problem, it’s definitely worth checking with a plumber.

We hope you learned a thing or two from today’s article on water pressure. Of course, getting the pressure right is only the start — if you’d like us to pair that with a top-notch whirlpool bath or shower, all you have to do is ask.
