At Citywide Plumbers, we understand that not every bathroom issue requires a full-scale service call. Some minor repairs can be managed on your own, saving both time and money—provided you know what to do. This guide walks you through the most common DIY bathroom repairs, along with tips on when to stop and call in a professional.
1. Slow Draining Sink – Clear the Waste Trap
Problem: Water pooling around your basin? Likely a clogged trap.
DIY Fix:
-
Place a bowl under the U-bend.
-
Unscrew the fittings, remove debris, rinse, and reattach.
-
Avoid over-tightening to prevent cracks.
When to Call Us:
If it smells bad, leaks, or doesn’t resolve with cleaning, our team can sort it professionally and hygienically.
2. Weak Toilet Flush – Check the Flapper
Problem: Toilet not flushing fully or water runs constantly.
DIY Fix:
-
Remove the cistern lid and inspect the flapper valve.
-
Replace if worn or not sealing properly.
-
Also check chain tension and fill level.
When to Call Us:
If you’ve tried adjustments but it still fails to flush, we’ll diagnose the mechanism safely and quickly.
3. Mouldy Sealant – Re-silicone Edges
Problem: Discoloured or peeling silicone around baths and showers.
DIY Fix:
When to Call Us:
If water damage is visible beneath the seal or tiles are loose, call us before things worsen.
4. Radiator Not Heating – Bleed It
Problem: Bathroom towel radiator is cold at the top.
DIY Fix:
-
Use a radiator key to slowly release air from the valve.
-
Catch water drips in a towel.
-
Once water flows steadily, close the valve.
When to Call Us:
If there's rust, brown water, or no improvement, the system might need power flushing—something we handle expertly.
Safety First: When Not to DIY
-
Gas-related issues? Never DIY—this is illegal without Gas Safe certification.
-
Major leaks or flooding? Shut off your water and call us immediately.
-
Water pressure too high/low? Could be a deeper system fault.
-
Electrical near water? Dangerous—do not attempt.
