Water Pressure Problems Hampstead: Complete Solutions Guide
Poor water pressure affects everything from showers to washing machines. Our expert water pressure service in Hampstead and NW3 diagnoses and fixes all pressure issues. Whether too low or too high, we restore optimal water pressure to your property.
Understanding Water Pressure
Normal Pressure Ranges
Ideal Pressure:
- 1.5 to 3 bar optimal for most homes
- 1 bar minimum for mixer showers
- 2+ bar for power showers and appliances
- 3+ bar for high-performance fixtures
Measurement:
- Bar: UK standard (10 bar = atmospheric pressure)
- PSI: Pounds per square inch (1 bar = 14.5 PSI)
- Metres head: Height of water column (10m = 1 bar)
Common Pressure Problems
Low Pressure (Below 1 bar):
- Weak shower flow
- Slow-filling baths
- Poor washing machine performance
- Insufficient boiler pressure
- Appliance malfunctions
High Pressure (Above 5 bar):
- Noisy pipes (water hammer)
- Leaking taps and valves
- Shortened appliance lifespan
- Increased water waste
- Potential pipe damage

Frequently Asked Questions
Q: How much does it cost to fix low water pressure?
A: Diagnosis costs £85-125. Solutions range from £85 (simple valve adjustment) to £1,200+ (pump installation). We'll provide exact costs after assessment.
Q: Can you increase water pressure?
A: Yes, through pump installation (£600-1,200), pipe upgrades (£400-1,200), or both. We'll recommend the best solution for your property.
Q: Why is my shower pressure so low?
A: Common causes: low mains pressure, limescale, undersized pipes, shared supply, or partially closed valves. We'll diagnose and fix.
Q: Is high water pressure dangerous?
A: Above 5 bar can damage appliances, cause leaks, and create water hammer. We install pressure reducing valves (£180-320) to protect your property.
Q: How long do pressure pumps last?
A: Quality pumps last 10-15 years with proper maintenance. Annual servicing extends this to 15-20 years.
Q: Can you help with period properties?
A: Yes, we specialize in sensitive installations that respect property character while solving modern pressure needs.
