Ian White2024-11-04Trustindex verifies that the original source of the review is Google. Great Job by them, I had a slow draining kitchen sink, that refused to be fixed by me. I called Flow Sure Drains, and it looked like it was going to defeat him as well, but Tony refused to give up and with some detective work figured out the issue, despite me giving him incorrect information, given to me by a company I paid 5 years ago to survey my drain system, on which inspection cover was Surface water and which was foul water. Turns out both were foul water! So thank you for giving up Russell Jones2024-08-18Trustindex verifies that the original source of the review is Google. Fantastic service.

When to Call About a Blocked Toilet
Signs Your Toilet Is Blocked
A blocked toilet can be messy, stressful, and even a health risk if not fixed quickly. Many small problems start with signs people ignore. Here’s how to tell if your toilet needs professional attention:
- Water rising too high when you flush: This is often a sign of a blockage in the trap or pipes.
- Water drains away slowly: If the flush takes too long to go down, there may be a partial blockage.
- Bad smells from the toilet: Waste stuck in the system can cause unpleasant odours
- Toilet won’t flush at all: This is a clear sign that the pipe is blocked
- Water or waste backing up: Water coming back into the toilet or nearby drains needs urgent attention.
If you’re dealing with any of these signs, Flow Sure Drains can fix your blocked toilet fast, anywhere in Bristol or Chepstow.

FAQ’s
1. What causes a blocked toilet?
A blocked toilet is often caused by too much toilet paper, wet wipes, or sanitary items being flushed. In some cases, the blockage may be deeper in the pipe, caused by a build-up of waste, foreign objects, or even tree roots in the drain outside.
2. How do I know if my toilet is blocked?
Signs of a blocked toilet include:
Water rising too high after flushing
Water draining away slowly
Gurgling noises from the bowl
Unpleasant smells
Overflowing or backflow from the toilet or nearby drains
If you notice any of these signs, it’s best to deal with the blockage straight away.
3. How to unblock a badly blocked toilet?
To unblock a badly blocked toilet, start by stopping the water supply if it’s at risk of overflowing. Use a plunger with firm, steady pressure to try and break the blockage. If that doesn’t work, a toilet auger (a long, flexible tool) can help reach deeper into the pipe.
If the problem continues, it could be linked to issues elsewhere in your system, such as a blocked shower or main drain. A professional inspection may be needed to fix the problem properly.
4. How to unblock a badly blocked toilet without a plunger?
If you don’t have a plunger, you can try pouring hot (but not boiling) water into the bowl from waist height to add pressure. Follow with a mix of baking soda and vinegar, leave it for 15–30 minutes, then flush. You can also try using a toilet brush or a wire coat hanger (with care) to break up the blockage.
If your toilet remains blocked — or you also notice a blocked shower or slow-draining sinks — the issue may be further down the line and require expert help.
5. Why does my toilet keep blocking?
A toilet that keeps blocking may be caused by:
Flushing items that don’t break down (like wipes or sanitary products)
A low water pressure flush
A narrow or damaged drain pipe
A more serious issue in the main drain
Sometimes, a repeated toilet blockage can be linked to other drainage problems in your home, such as a blocked shower or shared waste pipe. A professional inspection can help find the root cause and stop the problem from returning.
6. Can a blocked toilet fix itself?
No, a blocked toilet will not usually fix itself. While water might slowly drain over time, the blockage often remains and can get worse. Ignoring it could lead to an overflow, pipe damage, or a more expensive repair.
It’s best to fix a blocked toilet as soon as possible to avoid further issues.
7. When should I call a professional for a blocked toilet?
You should call a professional if:
DIY methods haven’t worked
The toilet keeps blocking repeatedly
Water is backing up or overflowing
There’s a strong smell or gurgling sound
More than one drain is affected
At Flow Sure Drains, we specialise in clearing any blocked toilet quickly, safely, and with no mess.
