Increasing Water Pressure
Are you tired of having a weak shower? Give us a call today
Fixing low water pressure has been a passion of mine ever since a first moved to England and shared a house in London with 4 other Saffa’s. We had one bathroom with a little electric shower over the bath. Only 4/5 of the holes in the shower head seemed to work and you probably would have had better shower pressure if you’d done what the guys doing in the picture. Since that grim introduction to showering in the UK, I’ve tried & tested every solution to increasing your water pressure available. I know what works and what doesn’t, and I can help you.

On this job (pictured) we needed to increase the water pressure to 3 bathrooms + kitchen, utility, cloakroom.
We went for a booster pump + break tanks (cold water storage tanks, similar to what you’d find in your loft really). Basic principle is, the weak incoming cold water mains fills the break tank(s), and then we have reservoir of stored water to boost from. We can set the pump to the pressure we desire / require and we’re in control.
The pump we went for was a “constant pressure” booster pump, meaning that if we set it to 4 Bar, and you open your shower, you’ll get 4 Bar. Then if someone opens a second tap, the pump will work a bit harder to give you 4 Bar at both…and so on. We tested it with all three showers and the kitchen tap running, and had great pressure everywhere. I’m using the term “water pressure” here but really I’m talking about your water pressure and flow rate.
Flow rate is really the key factor in being able to have more than one tap open at a time. Because it’s your flow that gets split in two, and it’s your flow that needs to be boosted. Your pressure actually doesn’t change at all, but people equate good pressure with a having a good shower).
The Bucket Test
If you’d like to know what your flow rate is at home, here’s a quick and easy way you can work it out. Put a 10 litre bucket under your garden tap, open the tap fully and time how long it takes to fill the bucket. If it takes 30 seconds to fill the bucket then you have a flow rate of 20 litres/min. The real test though, is then to open a second tap and do the test again with two taps open. Because that’s what will be happening when you’re in the shower and somebody turns the washing machine on.
