3 Reasons Why Your Toilet Won’t Flush And How to Fix It (Norfolk Homeowners & Businesses Guide)

A toilet that won’t flush properly is more than just a daily nuisance, it could be a warning sign that something deeper is wrong with your drainage system. Whether you’re a homeowner in Norwich or a business in King’s Lynn, HFS Waste Management is here to help you spot the issues before they become major (and costly) problems.

Here are the top 3 reasons your toilet might not be flushing and how to fix it:

1. Low Water Levels in the Cistern

   
   

The Problem:

If you lift the toilet lid and the water level is unusually low, it won’t generate enough force to flush waste properly.

The Fix:

Check the water valve behind the toilet it may have been accidentally turned off. If the valve is open and the water still won’t rise, there could be a problem with your float or fill valve. These are usually inexpensive to replace and easy to install.

Pro Tip: Still not working? There may be a blockage in the internal mechanism, that’s when calling a professional like HFS Waste Management is your best bet.

2. Blocked Toilet or Drain Line

   
   

The Problem:

Toilet paper, wipes (even “flushable” ones), or foreign objects can clog your toilet or the drain beyond it, stopping the flush.

The Fix:

Start with a plunger. If that doesn’t work, a toilet auger or snake may help shift the blockage. But if you notice water backing up into other drains (like your shower or sink), you’re likely dealing with a deeper issue in the drainage system.

Expert Advice: Norfolk’s older drainage systems are particularly vulnerable to build-up and tree root intrusions. Our CCTV drain survey service pinpoints blockages fast, without digging up your garden!

3. Septic Tank or Sewer Line Issues

The Problem:

If your property uses a septic tank or has old sewer lines, a toilet that won’t flush could mean they’re full or damaged.

The Fix:

This isn’t a DIY job. Septic tanks need regular emptying, and any issue with sewer lines can quickly escalate. HFS Waste Management offers septic tank emptying across Norfolk, using state-of-the-art equipment.
