Nothing beats a nice warm shower after a long day at work. But imagine stepping in, only to be greeted by a weak trickle instead of a satisfying stream. 

Low water pressure doesn’t just affect your shower. If you are dealing with low water pressure, it can slow down your taps, make toilet flushes frustrating, and even impact appliances like washing machines and dishwashers. When it comes to keeping your home running smoothly, reliable domestic plumbing is essential. That’s why many households trust L G Bullen for expert plumbing in Liverpool.

If you notice a drop in pressure, it is worth investigating. Here are some of the most common culprits: 

  • Clogged Pipes 

Over time, mineral deposits, rust, or debris can build up inside your pipes – especially in older homes or areas with hard water. This restricts the flow and reduces pressure at the tap. Older homes in Liverpool often experience low water pressure due to clogged pipes, making professional domestic plumbing support invaluable. 

  • Leaks in the Plumbing System 

Even a small leak can divert water away from where it is needed. Look out for damp patches, mould, or an unexplained increase in your water bill. 

  • Pressure Regulator Issues 

Some homes have a pressure-reducing valve to keep water pressure within safe limits. If this is faulty or misadjusted, it can cause pressure to drop throughout the house. 

  • Closed or Partially Closed Valves 

Your internal stop tap (usually under the kitchen sink) controls the flow of mains water into your home. If it is fully open, it can restrict pressure across all fixtures. 

  • Municipal Water Supply Problems 

Sometimes the issue isn’t in your home at all. Maintenance work, burst mains, or high demand in your area can temporarily reduce pressure. Check with your water supplier if you suspect this. 

  • Old or Inadequate Plumbing 

Narrow or outdated pipework may not be able to handle modern water demands. If your home’s plumbing hasn’t been updated in decades, it might be time for an upgrade. Professional plumbing in Liverpool services like L G Bullen can advise on whether your system needs replacing. 

Hot vs Cold Water Pressure 

If the problem affects your hot water only, the issue is likely to be internal. Cold water typically comes from the mains, while hot water is heated and stored in your boiler or cylinder. In this case check your boiler settings or consult a professional to impact your heating system. Learn more about our boiler servicing or explore our plumbing repair services.
