What to do if water won't drain?

If water is no longer draining properly from your plughole, the cause is usually a blockage in the pipe. In some cases, simple methods such as hot water, washing-up liquid or a plunger can help, but for more stubborn blockages, a specialist product is often required. HG offers a range of effective solutions for both light and severe blockages in sinks, showers and toilets. If the problem persists after treatment, it is advisable to contact a professional plumber to prevent further damage.

HG solutions for a blocked drain

HG offers several products depending on the type and severity of the blockage:

• For a normal blockage in the sink, toilet or shower drain, HG drain and plug unblocker (500 ml) is a ready-to-use solution. Pour 500 ml into the drain, leave to work for 5 minutes and rinse thoroughly with water.
• For stubborn blockages in the kitchen, we recommend HG kitchen drain and plug unblocker first. This enzyme-based product is designed specifically for grease and food residue in kitchen drains and works effectively without damaging pipes.
• For the most stubborn blockages in the kitchen and bathroom, HG duo unblocker is the solution. This powerful two-component system works on the most severe blockages in both kitchen and bathroom drains.
• If you have a blockage where water has stopped flowing completely, you can use HG drain and plug unblocker gel. The gel sinks directly to the blockage and can be left to work overnight if necessary.

Solutions for a blocked drain

Before using a specialist product, you can try the following methods carefully:

• Pour hot water mixed with washing-up liquid down the drain. The heat and grease-dissolving properties can clear minor blockages.
• Use a plunger to create pressure and loosen the blockage. Place the plunger over the drain opening and pump vigorously up and down.
• Use a drain snake to remove hair or debris. Be careful not to damage the drain.

If these methods do not solve the problem, an HG product is the next recommended step. Always follow the instructions on the packaging for safe and effective results. If the problem persists, call a professional plumber to prevent any serious damage.

Causes of water that won't drain

Common causes of water not draining include:

• Build-up of hair, soap residue or limescale in the drain pipes
• Grease and food waste accumulation in kitchen pipes
• Damaged or ageing pipes that restrict water flow
• Blockages further down the drainage system or municipal sewage problems

To prevent issues in the future, carry out regular maintenance using HG drain cleaner sticks monthly in your drain to prevent dirt from building up. Avoid flushing unsuitable materials down the drain and consider professional inspection if problems persist. For persistent problems, it's advisable to call a plumber for inspection and repair to maintain proper drainage in your home.
