Common Summer Plumbing Problems in Hertfordshire (And How to Prevent Them)

At C A Waters Plumbing & Heating, we know that summer brings its own set of plumbing challenges for homeowners across Hertfordshire, from Radlett and Bushey to Chorleywood and beyond.

Here’s a look at the most common summer plumbing issues we’ve dealt with — and what you can do to avoid a costly emergency callout.

Outdoor Tap Leaks & Garden Hose Issues

During summer, outdoor taps and hose connectors get heavy use. Loose fittings, cracked washers, or frost-damaged pipes from winter can start to leak under pressure.



Prevention tip:

Check garden taps for drips, corrosion or loose joints before regular use. If unsure, call your local Hertfordshire plumber to inspect and reseal.

Shower Drain Blockages

With more frequent showers during warmer weather — and sometimes sand, dirt or even pet hair being washed away — shower drains can clog quickly.

Prevention tip:

Use a drain catcher to trap debris and clean it weekly. A slow-draining shower? We offer rapid-response drain clearing in Bushey, Radlett and surrounding areas.

Leaking Toilets or Constant Refills

Toilets working overtime during school holidays can develop flush or refill faults. Leaky valves waste water and increase bills.

Prevention tip:

Listen for constant running water or check for damp around the base. If in doubt, we can replace faulty cistern components quickly.

Burst Pipe Risks from Pressure Spikes

Although burst pipes are more associated with winter, hot weather can expand pipework and lead to cracks or joint failures — especially in older homes.

Prevention tip:

Schedule a summer check-up of exposed pipework and garden plumbing. We cover all of Hertfordshire, North London, and nearby areas.

Boiler Pressure Fluctuations

Did you know boiler pressure issues can spike during warmer months too? Reduced use and trapped air in heating systems can trigger fault codes.

Prevention tip:

Bleed radiators and monitor the pressure gauge. If you're unsure, our Gas Safe engineers can diagnose and fix any boiler pressure issue promptly.
