Owning a home comes with its fair share of responsibilities, and one of the most important systems to maintain is your plumbing.
While it’s easy to take running water and flushing toilets for granted, ignoring small issues can lead to costly repairs later.
That’s why we’ve put together this comprehensive guide of essential plumbing tips every UK homeowner should know.
Whether you’re living in a new-build or an older property, these simple, proactive steps can help you avoid major plumbing headaches.
If you need expert help, the team at GSM Builders is always here to assist across London and the surrounding areas.
1. Understand Your Water Main
Every homeowner should know where their main water shut-off valve is. This valve controls the entire water supply to your home.
In an emergency, like a burst pipe, turning this off quickly can prevent flooding and severe damage.
Tip: It’s usually located near where the water pipe enters your home—often under the kitchen sink or near the front wall.
2. Fix Dripping Taps Promptly
A dripping tap might seem like a minor annoyance, but it can waste litres of water over time. It may also be a sign of worn-out washers or faulty fixtures.
Replacing a tap washer is cheap and easy, and doing so can save water and reduce your utility bills.
3. Don’t Ignore Slow Drains
A slow-draining sink or bath is often the first sign of a blockage. Avoid using chemical drain cleaners, which can damage your pipes. Instead, use a plunger or a natural solution like baking soda and vinegar.
If the problem persists, it could be deeper in the system—call in a professional plumber to check for pipe issues.
4. Know What NOT to Flush
The toilet is not a bin. The only things that should go down the toilet are human waste and toilet paper. Flushing wipes (even the ones labelled as “flushable”), cotton buds, or sanitary items can clog pipes and damage your home’s plumbing system.
5. Insulate Your Pipes in Winter
Frozen pipes are a common issue during the cold UK months. When water freezes, it expands and can burst your pipes, causing major leaks. Insulate exposed pipes in lofts, basements, and external walls using foam insulation sleeves.
Also, keep your heating on low during cold spells—even when you’re not home.
6. Regularly Check for Leaks
Leaks are not always obvious. Small leaks under sinks or behind appliances can waste water and cause mould. Make it a habit to check under sinks, around the toilet base, and near your boiler for signs of moisture or musty smells.
Spotting and fixing leaks early can save you money and prevent structural damage.
7. Clean Your Showerhead
Over time, UK hard water causes limescale build-up, especially on showerheads. This can reduce water pressure and even block the nozzles. Remove the showerhead and soak it in vinegar overnight to keep it clean and working efficiently.
8. Install Strainers in Sinks and Showers
Hair, soap scum, and food waste are the most common causes of drain blockages. Installing simple mesh strainers in your sinks and showers will trap debris and keep it from entering your plumbing system. They’re cheap, easy to clean, and save you from future plumbing bills.
9. Know Your Water Pressure
Low water pressure can be a sign of a hidden leak or sediment build-up in your pipes. High pressure, on the other hand, puts strain on your plumbing and can lead to leaks or broken appliances. Use a water pressure gauge or ask your plumber to check and adjust it as needed.
10. Service Your Boiler Annually
Your boiler is the heart of your home’s heating and hot water system. An annual check ensures it’s running safely and efficiently. It can also catch potential problems early, saving you from unexpected breakdowns in the middle of winter.
Always use a gas safe registered engineer for any boiler servicing.
11. Learn Basic Plumbing Tools
Having a few basic plumbing tools can save you in emergencies. A plunger, pipe wrench, adjustable spanner, and a roll of PTFE tape are great to have in your toolkit. Knowing how to use them properly can help you handle small issues before calling in the professionals.
12. Check Outside Drains and Gutters
Leaves, mud, and debris can clog outside drains, especially in autumn and winter. Blocked gutters and drains can overflow, causing water to pool around your home’s foundation or enter your basement. Regular cleaning and inspection of outdoor drainage are essential.
13. Upgrade Old Plumbing
If your home is over 30 years old and has never had a plumbing upgrade, it might be time to consider replacing older pipes. Old galvanised or lead pipes can corrode or pose health risks. Modern copper or plastic pipes are more reliable and safer.
Speak to GSM Builders if you’re unsure whether your plumbing needs an upgrade.
14. Be Careful When Drilling
Before drilling into walls, floors, or ceilings, check for hidden pipes. Damaging a pipe can cause flooding and expensive repairs. Use a stud finder or ask a professional if you’re unsure.
15. Use a Reliable Plumber
Finally, build a relationship with a trusted, experienced plumber. Having someone you can call in an emergency makes all the difference. At GSM Builders, our qualified team is ready to help with anything from blocked drains to full plumbing system installations.
