Most plumbing systems are designed to work quietly in the background. But when something goes wrong, it’s rarely subtle and rarely cheap to fix. Whether you own or rent your home, knowing how to maintain your system can save you time, money and hassle. This guide covers the essentials of plumbing maintenance, with practical tips to help you stay ahead of common domestic plumbing issues.

1. Keep an Eye Out for Leaks

Small leaks are easy to overlook but can cause serious damage if left unattended. Moisture behind units, under sinks or around toilets might indicate a problem. What to do:

• Check under basins and kitchen sinks regularly
• Look for any signs of damp or mould near pipework
• Listen out for dripping taps or trickling water

2. Monitor Your Water Pressure

Water pressure that’s too low or suddenly drops could be a sign of a hidden leak or blockage. High pressure can also damage fixtures and joints. What to do:

• Install a pressure gauge on an outside tap to check levels
• If pressure is outside the 1–3 bar range, seek advice from a plumber
• Report any sudden changes that affect more than one fixture

3. Maintain Clear and Free-Flowing Drains

Blocked drains are one of the most common complaints in domestic plumbing. Preventing them is often easier than fixing them.

What to do:

• Fit strainers over plug holes to catch debris
• Don’t pour oil or grease down the kitchen sink
• Use boiling water and bicarbonate of soda to help keep pipes clear

4. Inspect for Pipe Corrosion

Older homes with metal pipework may experience corrosion over time. This can weaken pipes and affect water quality. What to do:

• Inspect accessible pipework for green, white or rusty marks
• If your water looks brown or has a metallic taste, call a professional

5. Prevent Freezing in Cold Weather

Freezing temperatures can cause pipes to burst, especially in unheated areas like lofts and garages. What to do:

• Insulate pipes in cold spots
• Keep heating on low during freezing weather, especially overnight
• Open cupboard doors to allow warm air to reach exposed pipework

6. Schedule an Annual Boiler Service

Your boiler is a key part of your plumbing system. A service keeps it safe and ensures it runs efficiently throughout the year. What to do:

• Book a service with a Gas Safe registered engineer once a year
• Don’t ignore warning lights or fault codes

7. Know How to Shut Off Your Water Supply

If a pipe bursts or a leak starts suddenly, shutting off the water quickly can limit damage. What to do:

• Locate the internal stopcock, usually under the kitchen sink
• Check it turns easily. If not, it might need replacing
• Make sure everyone in your household knows where it is

8. Review Water Bills for Unexpected Changes

A sharp rise in your water bill without increased usage could suggest a leak somewhere in your system. What to do:

• Track your usage and billing
• If usage jumps without explanation, get your plumbing inspected

9. Keep Toilets in Working Order

A constantly running toilet or one that doesn’t refill properly wastes water and increases wear on internal parts. What to do:

• Check cisterns for slow leaks or trickling water
• Replace washers and flush valves if they show signs of wear
• Never flush items like wipes or sanitary products, even if labelled ‘flushable’

10. Book a Plumbing Maintenance Check

Some issues are easy to miss without professional experience. Regular inspections help catch things before they escalate. What to do:

• Schedule a routine inspection once a year
• Ask your plumber to check pipework, fixtures, boiler and drainage
• Discuss any recurring problems or long-term concerns
