Most plumbing problems don’t start with a dramatic burst pipe. They start with little annoyances:
- A tap that never quite turns off
- A toilet that keeps running
- A shower that feels more like a drizzle than a rinse
Easy to ignore… until they become bigger, more expensive problems.

10 Common Home Plumbing Problems (and What’s Really Going On)
1. Dripping Taps
That constant drip is more than just annoying – it’s wasted water and money.
What’s usually wrong:
- Worn-out washer or cartridge
- Damaged O-ring
- Corroded or worn valve seat
How the pros fix it:
- Isolate the water supply
- Dismantle the tap body
- Replace the faulty washer, cartridge, or O-ring
- Reassemble and test for smooth operation and a proper seal
DIY or call a pro?
- Confident DIYer with the right tools? You might replace a washer.
- If it’s a modern mixer tap, ceramic cartridge, or you’re unsure – call a pro.
2. Running Toilets
You flush, it refills… and then it just keeps running. That’s water (and money) literally down the drain.
What’s usually wrong:
- Faulty flapper or flush valve
- Fill valve not shutting off properly
- Float set too high
- Worn internal parts
How the pros fix it:
- Inspect internal components in the cistern
- Adjust or replace the flapper and/or fill valve
- Set the water level correctly
- Check for any cracks or hidden leaks
DIY or call a pro?
- Basic adjustments or replacing a simple flapper can be DIY.
- If you’ve tried that and it’s still running – time for a plumber.
3. Low Water Pressure
Showers that feel weak, taps that trickle – frustrating and often a sign of a bigger issue.
What’s usually wrong:
- Limescale build-up in shower heads and tap aerators
- Partially closed isolation valves
- Hidden leaks in the system
- Pressure-reducing valve issues
- Problems with the supply into the property
How the pros fix it:
- Check pressure at various outlets to narrow down the cause
- Clean or replace aerators and shower heads
- Inspect valves and pipework for restrictions or leaks
- Test and adjust pressure-reducing valves if fitted
DIY or call a pro?
- Cleaning a shower head or tap aerator is easy DIY.
- If pressure is low throughout the house or suddenly drops – get a professional to investigate.
4. Noisy Pipes (Banging, Knocking, Whistling)
Your plumbing shouldn’t sound like a drum kit.
What’s usually wrong:
- “Water hammer” – sudden pressure changes when taps or valves shut
- Poorly secured pipework
- High water pressure
- Air in the system
How the pros fix it:
- Check water pressure and fit or adjust pressure-reducing valves if needed
- Secure loose pipework with proper clips and supports
- Fit water hammer arrestors where appropriate
- Bleed air from the system
DIY or call a pro?
- You can visually check for obvious loose pipes.
- Anything involving pressure, valves, or system changes – leave to a plumber.
5. Slow-Draining Sinks and Showers
Water pooling around your feet or sitting in the sink is usually a sign of a blockage starting.
What’s usually wrong:
- Hair, soap scum, grease, and food particles building up in the trap or pipe
- Poor pipe fall or gradient
- Deeper blockage further along the line
How the pros fix it:
- Remove and clean traps
- Use professional-grade drain tools (not just harsh chemicals)
- Check for underlying issues with pipework or venting
- If needed, use cameras to inspect deeper blockages
DIY or call a pro?
- Pull out visible hair, clean the trap, use a simple plunger – DIY.
- Repeated blockages, bad smells, or multiple drains affected – call a pro.
6. Frequent Clogged Toilets
Everyone gets the odd blockage. But if it’s happening regularly, something’s off.
What’s usually wrong:
- Too much paper or non-flushable items (wipes, sanitary products, cotton buds)
- Low-flow toilets with weak flush
- Partial blockage in the soil pipe or further down the line
How the pros fix it:
- Use professional plungers or augers to clear blockages
- Inspect the toilet and pipework for design or installation issues
- If needed, use CCTV to check for tree roots, collapsed pipes, or serious obstructions
DIY or call a pro?
- One-off blockage? Try a plunger.
- Constantly clogging, or water nearly overflowing every time? Get a plumber in.
7. Leaking Pipes (Visible or Hidden)
Small leaks can cause big damage if ignored.
What’s usually wrong:
- Loose joints or fittings
- Corroded or cracked pipes
- Freezing damage in cold weather
- Poor previous repairs
How the pros fix it:
- Isolate the affected section
- Repair or replace damaged pipework and fittings
- Check nearby sections for signs of wear or stress
- Test the system under pressure to confirm the fix
DIY or call a pro?
- Temporary leak tape or a bucket is fine as a short-term measure.
- Actual pipe repairs should be done by a professional – especially near electrics or inside walls and ceilings.
8. Water Heater or Boiler Issues (No Hot Water)
No hot water is more than an inconvenience – it can indicate a safety issue.
What’s usually wrong:
- Faulty thermostat or heating element
- Limescale build-up
- Pressure or temperature relief valve issues
- For gas boilers: ignition, sensor, or other gas-related faults
How the pros fix it:
- Test electrical components and thermostats
- Descale or flush the system if needed
- Inspect and replace faulty valves
- For gas appliances, a Gas Safe registered engineer must handle it
DIY or call a pro?
- You can check the power is on and reset the unit if the manufacturer allows.
- Anything beyond that – especially gas – is strictly professional territory.
9. Smelly Drains
Unpleasant smells from sinks, showers, or floor drains are more than just annoying.
What’s usually wrong:
- Traps drying out (no water seal)
- Build-up of organic matter in pipes
- Venting issues
- In some cases, problems with the main sewer line
How the pros fix it:
- Clean and flush traps and pipework
- Check that traps are correctly installed and holding water
- Inspect venting and, if needed, the main sewer connection
DIY or call a pro?
- Run water into rarely used drains to refill traps, clean visible gunk – DIY.
- Persistent smells, especially with gurgling noises or slow drains – call a plumber.
10. Outdoor Tap and Hose Bib Problems
Leaking outdoor taps waste water and can cause damp issues.
What’s usually wrong:
- Worn washers or cartridges
- Frost damage
- Loose fittings or poor installation
How the pros fix it:
- Replace washers or cartridges
- Repair or replace damaged taps and pipework
- Fit proper frost-proof taps where appropriate
DIY or call a pro?
- Simple washer replacement can be DIY.
- Any signs of cracking, freezing damage, or leaks into the wall – call a pro.
DIY vs Call-a-Pro: A Simple Rule of Thumb
You don’t need to call a plumber for every tiny issue – but you also don’t want a “cheap fix” turning into a big repair.
Use this simple rule:
- DIY is usually fine when:
- You’re cleaning (shower heads, traps, aerators)
- You’re doing basic, reversible adjustments
- There’s no gas, electrics, or structural risk involved
- You’re 100% sure how to turn the water off
- Call a residential plumber when:
- You’re not sure what’s causing the problem
- The same issue keeps coming back
- There’s a leak inside walls, ceilings, or near electrics
- It involves boilers, cylinders, or gas appliances
- You’d be guessing rather than following clear instructions
A good residential plumber will happily tell you what you can do yourself and what really needs a professional.
Residential Specialist vs General Handyman: What’s the Difference?
It’s tempting to call a general handyman for “small” plumbing jobs. Sometimes that’s fine – but there are key differences.
What a residential plumbing specialist brings:
- Deeper diagnosticsWe don’t just fix the symptom; we look for the cause (pressure, design, venting, etc.).
- Proper tools and partsProfessional-grade equipment and quality fittings designed to last.
- Knowledge of regulations and best practiceEspecially important for hot water, unvented cylinders, and anything connected to the mains.
- System-wide thinkingWe understand how one small change can affect the whole system.
A handyman might be great for shelves, painting, or minor odd jobs – but when it comes to the plumbing that protects your home, a residential specialist is usually the safer, more cost-effective choice in the long run.
Maintenance Tips to Prevent Repeat Issues
A little routine care goes a long way. Here are some simple habits that help avoid repeat call-outs:
- Clean shower heads and tap aerators regularly
Soak in vinegar to remove limescale and keep pressure up. - Watch what goes down the drains
Use strainers in sinks and showers. No grease, oil, coffee grounds, or food scraps down the kitchen sink. - Only flush the “3 Ps”
Pee, poo, and (reasonable amounts of) paper. No wipes, even if they say “flushable.” - Check for small leaks monthly
Look under sinks, around toilets, and near appliances. Catching a tiny drip early is far cheaper than repairing water damage later. - Know where your stopcock is
Make sure everyone in the house knows how to turn the water off in an emergency. - Schedule periodic professional checks
Especially for older properties, boilers, and cylinders. A quick annual or biannual check can prevent surprise failures.
Final Thought: Your Home Deserves a Proper Residential Plumber
Dripping taps, running toilets, low pressure, and noisy pipes might seem like small things – until they’re not.
A residential plumbing specialist:
- Knows how home systems really work
- Spots early warning signs before they become big problems
- Fixes issues properly, not just “for now”
