I’ve had Antony out to look at our drains on a couple of occasion, both times prompt, knowledgeable and charging clear and fair prices. Very happy with the service! 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.

Warning Signs of a Blocked Drain
Blocked drains are a common issue in both residential and commercial properties across Bristol and Chepstow. Identifying the early signs of a blockage can help you avoid costly repairs and water damage. Here are the most common signs that you may need professional drain unblocking in Bristol or Chepstow:
- Slow-Draining Water: If water is taking longer than usual to drain from your sinks, baths, or showers, it could be an early sign of a blockage in your pipes.
- Bad Smells: Persistent, unpleasant odours coming from plugholes or drains often indicate a build-up of waste, grease, or debris.
- Gurgling Sounds: Unusual gurgling or bubbling noises from your drainage system suggest trapped air caused by a partial blockage.
- Water Backing Up: If water rises in one fixture (e.g. a sink or shower) when another is in use, it points to a serious obstruction in the main drain.
- Frequent Toilet Blockages: Toilets that clog regularly or flush inefficiently could indicate a deeper issue that requires professional attention.
- Damp Patches or Overflow: Water pooling around outdoor drains or damp patches near internal drains may signal external drainage problems.
If you are experiencing any of these issues in your Bristol or Chepstow property, our expert team is here to help. We offer fast, reliable, and affordable drain unblocking services across the region, ensuring your system is flowing freely again in no time.

FAQ’s
1. How to unblock a drain?
You can try basic drain unblocking at home by pouring boiling water down the drain, followed by a mix of baking soda and vinegar. Let it sit for 15 minutes, then flush again. Use a plunger or drain snake if needed.
If this doesn’t work, or if water is backing up, it may be time for professional drain unblocking. At Flow Sure Drains, we offer fast, clean, and reliable services, including emergency drain unblocking when you need help right away.
2. How to unblock a shower drain?
Start by removing the cover and pulling out hair or debris. Then try hot water, a natural cleaner (baking soda and vinegar), or a drain snake. If water still drains slowly, the blockage could be further down.
For persistent problems, our team offers expert shower drain unblocking and fast response for emergency drain unblocking, available 24/7.
3. How to unblock a drain pipe outside?
Clear away leaves and dirt from the top of the drain. Use drain rods to push through the blockage and rinse with clean water.
If water overflows or smells bad, the problem might be deeper. This often needs professional drain unblocking or urgent help from our emergency drain unblocking team in your area.
4. How to unblock an external drain?
Remove the drain cover, clear surface debris, and use a drain rod or high-pressure water if needed. Wear gloves and take care around waste water.
If DIY doesn’t work, Flow Sure Drains can help with safe, professional drain unblocking, including 24/7 emergency drain unblocking for urgent issues.
