Water Supply Disruption in RH & TN Postcodes: What To Do During Ongoing Outages

Water Supply Disruption in RH & TN Postcodes: What To Do During Ongoing Outages

Recent water supply disruption across RH and TN postcode areas has left many households dealing with low pressure, intermittent supply or complete outages.

While most issues are caused by external mains supply problems, there are important steps you can take to protect your plumbing system and appliances during and after the disruption.

1️⃣ Turn Off Sensitive Appliances

If supply becomes unstable:

• Turn off washing machines
• Turn off dishwashers
• Avoid running combi boilers
• Delay filling baths

When water returns suddenly, pressure surges and air in the system can damage appliances.

2️⃣ Protect Your Boiler

Water outages can affect boiler pressure.

If your boiler runs dry or pressure drops too low, it may lock out.

Once supply is restored:

• Check boiler pressure (should sit around 1.0–1.5 bar when cold)
• Reset only if pressure is stable
• Do not repeatedly repressurise without checking for leaks

3️⃣ Run Taps Slowly When Supply Returns

When water returns:

• Open cold taps slowly
• Allow air to purge
• Expect spluttering initially
• Let water run clear before use

Discoloured water is common after outages and usually clears within minutes.

4️⃣ Check for Leaks

After supply restoration:

Inspect:

• Under sinks
• Around outside taps
• Radiator valves
• Washing machine hoses

Sudden pressure changes can expose weak joints.

5️⃣ Know Your Stop Tap Location

If pressure returns aggressively or you spot a leak:

• Turn off your internal stop tap immediately
• This prevents water damage

Every homeowner should know where this is located.

6️⃣ Store Emergency Water if Outages Continue

If disruption is ongoing:

• Store bottled water
• Fill containers in advance
• Keep some water aside for toilet flushing

Planning ahead reduces stress during extended outages.

When Should You Call a Plumber?

Most outages are supply-side issues. However, contact a professional if:

• Water pressure remains low after restoration
• You notice new leaks
• Your boiler repeatedly loses pressure
• Discoloured water continues
