Blocked Gullies

Dealing with Blocked Gullies

If you’ve ever noticed puddles of stagnant water forming around your outdoor drain, the culprit is likely a blocked gully. Domestic gullies play a crucial role in directing rainwater from your gutters, surface water from your garden, and wastewater from your household appliances into the proper drainage system. These gullies are equipped with a protective grid to shield them from garden debris. If you peer down into the drain, you’ll typically see water.

In this blog, the drainage experts at Drainflow will look at the causes of blocked gullies, offer tips on clearing the blockage, and explain when it’s time to call in the professionals. Drainflow is a drain clearance company operating across Bedfordshire, Buckinghamshire, Hertfordshire, and North London. For over two decades now, we’ve been tackling blockages in domestic, road, and commercial gullies.


What Causes Gully Blockages?

What Causes Gully Blockages?

Blocked gullies can be attributed to a variety of factors, with the most common culprits being leaves and garden debris, solidified fat or grease, and invasive tree roots that manage to infiltrate the drainage system. In regions with hard water, such as Bedfordshire, limescale deposits can accumulate within the pipes, eventually leading to blockages. Occasionally we find that the culprit is a toy car, or even a bunch of keys.

Tips for Clearing a Blocked Gully

If you’re a confident DIY enthusiast, tackling a gully blockage yourself is a possibility. However, we always advise seeking professional assistance if you have any doubts about your capabilities, as damage to drain pipes is a risk.

Here are the essential steps to follow when dealing with a blocked gully. You should wear protective gloves throughout the procedure:

  1. Clear Surface Debris. Start by removing any garden debris, leaves, or twigs from the top of the gully. Often, this simple action can resolve the issue. If not, proceed to the next step.
  2. Lift the Grate. Once you’ve lifted the grate from the drain, use a garden trowel to clear any accumulated leaves and debris. This may be enough to alleviate the blockage. If not, move on to the next step.
  3. Probe with a Drain Rod. Use a drain rod to carefully explore the inside of the drain, aiming to locate and dislodge the blockage. If you encounter resistance, gently prod with the rod to break it apart, taking care not to push it further into the drain.
  4. Flush the Drain. If you successfully dislodge the blockage, follow up with a hosepipe to flush the debris through the pipe.
  5. Apply Boiling Water. As a final step, pour boiling water down the gully. This action aids in dissolving fatty buildups and further breaks down hardened debris.

Remember, safety and caution should be your top priorities during the gully-clearing process. If in doubt, don’t hesitate to consult a professional for expert assistance.

When to Call a Drain Clearance Professional

If you’ve attempted the steps outlined earlier and have been unsuccessful in clearing the blockage or if you’re not comfortable with the DIY approach, it’s wise to enlist the services of a professional drain clearance expert. These professionals possess the knowledge and tools necessary to efficiently identify and remove blockages in your drainage system.

In cases involving stubborn issues such as tree roots, wedged objects, or accumulations of silt and grease, drain clearance specialists employ high-powered water jets capable of delivering pressures of up to 3000psi. This method, known as drain jetting, offers a comprehensive cleansing of your gully, ensuring it remains in excellent condition and free from unpleasant odours.
