Preventative Plumbing Maintenance: What Homeowners Should Check Regularly

Preventative plumbing maintenance is about finding small problems before they become emergencies. Homeowners can keep an eye on a number of simple warning signs, while a licensed plumber can inspect parts of the system that are difficult to assess safely or accurately.

For more detail on the service itself, see our preventative plumbing maintenance page.

Check for small leaks

Look under sinks, around toilets, near washing machines and around visible valves. Dampness, staining or swollen cabinetry may indicate a slow leak even when there is no obvious dripping.

• Check around flexible hoses and isolation valves.
• Look for corrosion, staining or moisture.
• Pay attention to musty smells inside cabinets.

Watch the behaviour of taps and toilets

Taps that are difficult to turn, mixers that drip and toilets that continue running can often be repaired before they fail completely. Repeated problems may also point to pressure or age-related issues.

Pay attention to water pressure

Very high pressure can place unnecessary stress on fixtures and hoses, while low pressure can make everyday plumbing frustrating. A plumber can test the pressure and assess whether a pressure limiting valve or repair is needed.

Keep an eye on drains

Slow sinks, showers that pool water and gurgling noises can be early blockage signs. Avoid relying on repeated chemical drain cleaners because they do not identify the actual cause of the restriction.

Know where your isolation points are

Homeowners should know how to isolate the water supply in an emergency. If valves are seized, damaged or inaccessible, it is better to discover that during routine maintenance than during a burst pipe.

Include appliances and external plumbing

Dishwashers, washing machines, fridge water connections, garden taps and exposed external pipework should be included in your checks. These connections are easy to forget until something leaks.

When to bring in a plumber

If you find recurring leaks, pressure changes, noisy pipes, damaged valves or ageing flexible hoses, professional maintenance can address several items during one visit.
