To help you get the most out of your shower, we help you answer the question “do I need a shower pump?”.
Buying a shiny new, all-singing, all-dancing shower is great, but if your water pressure isn't up to the task, you'll be left standing under a dribble, instead of the invigorating torrent you were hoping for.
To help boost your flow rate, a shower pump is often the best solution, but do you actually need one?
In this blog post we'll explain:
- How to check your water pressure
- How to identify your hot water system
- Which shower pump is right for you
- Next steps
Checking your water pressure
You should be able to immediately tell if your water pressure is poor by checking the flow rate of various water outlets in your home. If you have an existing shower, you will already have noticed that it isn't as powerful as you like. If you don't already have a shower, see how quickly your toilet cistern takes to refill or how quickly it takes to fill your bath. A good flow rate is considered to be anything over 15 litres per minute.
To get an accurate measure of your water flow (how quickly your water is delivered), check out our guide to understanding water pressure.
Identifying your hot water system
If you have identified that you have low water pressure, the next best step is to buy a shower pump which will help to increase the flow to your shower. But before you choose a pump, you will need to check which hot water system you have in your home.
To the uninitiated, this could be quite a daunting task, so that's why we've supplied this handy infographic, which will make it easy to identify your domestic water system.
Got a gravity fed system?
Normally found in older properties, a gravity fed system relies on a combination of factors: the mains pressure to your home and the distance between the cold water tank (which is normally located in the loft) and your shower head. Both these factors can have a significant impact on the pressure of water coming out of your shower, and older properties typically suffer from water pressure issues.
Do you have a positive or negative head?
With a gravity fed system, there is 1 extra step you must take before deciding what to do about your low water pressure. You will need to identify whether you have a "positive head" or "negative head" system. To find this out, see our handy infographic below:
What can you do?
You've now identified which type of flow your gravity fed system has, so here are your options when it comes to buying a shower pump:
Improving just a single, small shower (with a 100-120mm head)
Improving pressure in a small bathroom with shower (with a 100-120mm head)
Improving pressure in a bathroom with multiple outlets, including body jets or a property with multiple bathrooms
Positive or negative head:

To help you further, take a look at the table below, where you'll find some of our most popular showers and the pumps you can use with them.
Got a combi boiler?
Very common in modern homes, the combi boiler system is a high pressure vented water system, so there really shouldn't be a need for you to increase the pressure to your shower.
What can you do?
If you do have low mains water pressure or have a shower with multiple outlets, you could potentially invest in a whole-house pump. Contact us to find out what options are available to you.
Got an unvented system?
Commonly found in properties where there is no room for a cold water tank, this system features a separate metal-clad hot water tank and wall hung boiler.
