What Happens When the Water Comes Back On?

Common Plumbing Issues After Low Pressure or Supply Interruptions

Recent water supply issues in Tunbridge Wells have left many homes dealing with more than just dry taps. When water pressure drops or cuts out completely, it can cause a ripple effect through your plumbing system, sometimes leading to annoying or even costly problems.

Since the water started to flow back into the taps of Tunbridge Wells, there has been a rise in callouts related to issues triggered after the water comes back on. Here’s what to watch for and how to avoid long-term damage.

1. Airlocks in Your Pipes

When water flows inconsistently, or not at all, air can get trapped in your plumbing system. That air creates a blockage (an airlock) that prevents water from running freely.

Signs of an airlock:

• Taps spluttering or running dry

• Radiators not filling properly

• Odd noises in the pipework

• Inconsistent water pressure in certain rooms

Fix: You may be able to remove a minor airlock yourself - but if the issue persists, it’s time to call a plumber before the air causes damage.

2. Secondary Hot Water & Booster Pumps Running Dry

Many modern homes rely on pumps to boost water pressure or circulate hot water. If the water supply drops or air enters the system, these pumps may:

• Run dry

• Overheat

• Fail prematurely

A booster or hot water pump running without water can burn out quickly, leading to expensive repairs or full replacement.

If your water pressure has just returned, keep an ear out for unusual pump noises and check your system is repressurising correctly.

3. Worn or Damaged Components Failing

Low pressure and trapped air can push already tired components over the edge. Common issues include:

• Faulty mixer taps

• Leaky seals or joints

• Toilet cisterns failing to fill

• Valves sticking open or closed

If your plumbing system is older, even a short water outage can put strain on weak points - causing leaks or inefficient performance.

What You Can Do:

• Run cold taps slowly when the water returns

• Turn off pumps temporarily to avoid dry running

• Watch for unusual sounds, smells or leaks

• Call a Gas Safe engineer or plumber if anything feels off
