Why Your Home Has Low Water Pressure — And How to Fix It
Poor water pressure isn’t just annoying — it can make everyday tasks like showering or doing the dishes a real chore. If you're dealing with trickling taps, weak showers, or slow-filling appliances, you're likely experiencing low mains water pressure.
Common Causes of Low Water Pressure at Home
There are several reasons why your water pressure might be lower than expected:
Shared Supply or Peak Demand
If you live in a built-up area or new development, your mains supply might be shared with other homes. During peak usage (morning or evening), pressure drops as demand increases.
Distance from the Mains Supply
Homes located farther from the main water line or at a higher elevation tend to receive weaker pressure due to natural friction loss in the pipe network.
Old or Narrow Pipework
Older properties often have undersized pipes or internal corrosion that restricts flow.
Plumbing Restrictions
Partially closed valves, clogged filters, or faulty pressure-reducing valves can also choke water flow.
Low Pressure from the Water Company
Sometimes, it’s not your house — it’s the supply itself. Your local water provider might be delivering below-standard pressure, especially during maintenance periods.
How to Test Your Water Pressure
You can run a quick test using a pressure gauge attached to an outside tap or washing machine inlet. In the UK, typical mains pressure should be 1.5–3 bar. Anything below 1 bar is considered low.
How to Solve Water Pressure Problems
✅ Check Your Stop Tap
Ensure your internal stop tap is fully open. Even partially closed taps can seriously reduce flow.
✅ Clean Tap Aerators and Showerheads
Sediment or limescale can build up and reduce flow at the outlet — clean them regularly.
✅ Speak to Your Water Supplier
They’re responsible for delivering minimum pressure to your home — and may be able to inspect or confirm supply issues.
✅ Install a Water Pressure Booster
If all else fails, a pressure booster system is the most effective long-term fix. Our compact booster units with built-in pumps are designed to increase pressure throughout your home — without major plumbing changes.
