DIY Plumbing Fixes: What You Can Do & When to Call a Pro

Plumbing problems are a common occurrence in UK homes, from dripping taps to slow-draining sinks. While some issues require professional attention, many simple plumbing repairs can be tackled with basic tools and a bit of know-how. Homeowners often feel tempted to fix problems themselves, but without proper knowledge, DIY attempts can sometimes lead to bigger and costlier issues. It’s important to understand how to properly navigate the world of DIY plumbing fixes in the UK and learn about practical solutions for minor repairs, as well as when to call a plumber.

DIY Plumbing Fixes You Can Do Yourself

1. Unclog a Blocked Drain

A slow-draining sink can be frustrating, but in most cases, you can fix the issue without calling a plumber.

DIY Fix:

• Use a plunger to create suction in the drain and dislodge minor clogs.
• Try pouring a mixture of baking soda and vinegar down the clogged drain, then follow it with hot water to break down grease and debris.
• Unscrew the U-bend under the sink to check for the source of the clog, but place a bucket underneath first to catch any water and trapped debris.

When to Call a Pro:

• If multiple drains in the house are blocked, it could indicate a mainline issue.
• If the clog persists despite multiple attempts to clear it, contacting a professional may be necessary.

2. Fixing a Dripping Tap

A leak can waste a surprising amount of water over time, but there is often a straightforward way to fix a leaking tap.

DIY Fix:

• Turn off the water supply before starting any repairs.
• Unscrew the tap handle and remove the faulty washer or ceramic disc.
• Replace the washer and reassemble the tap before turning the water back on.

When to Call a Pro:

• If the leak continues after replacing the washer, it may be an indication of a deeper issue.
• If the tap body or internal components are damaged and need replacement, you’ll want to contact a professional.

3. Stopping a Running Toilet

A continuously running toilet can be frustrating and lead to higher water bills.

DIY Fix:

• Remove the water tank’s lid and check if the flapper valve is sealing properly.
• Adjust or replace the flapper or float mechanism as needed.
• Ensure the chain connected to the flush handle isn’t too tight or tangled.

When to Call a Pro:

• If the issue persists, as it could indicate a more complex valve or fill mechanism fault.

4. Clearing a Slow Shower Drain

Blocked shower drains often result from a buildup of hair and soap scum.

DIY Fix:

• Use a drain snake or a bent wire hanger to remove trapped hair and debris.
• Pour a mixture of baking soda and vinegar down the drain, then follow it with hot water.

When to Call a Pro:

• If the blockage is deep within the pipes and cannot be reached.
• If water starts backing up into the shower or bath.

5. Sealing Small Pipe Leaks

Leaks can quickly escalate if left unchecked, but minor leaks can often be sealed temporarily.

DIY Fix:

• Turn off the water supply before attempting any repairs.
• Apply plumber’s tape or epoxy putty to seal small leaks.
• Tighten loose fittings using an adjustable wrench.

When to Call a Pro:

• If the leak is large or located near a pipe joint.
• If the pipe is corroded and requires replacement.
