FAQs

How much Flash Sink and Drain Unblocker should I use?

Always refer to the specific dosage instructions on the product label, as this can vary depending on the severity of the blockage and the type of drain.

How long should I leave the product in the drain?

The recommended waiting time is typically between 15 minutes to a few hours, depending on the blockage. Check the product label for the exact duration.

Can I use this unblocker in my toilet?

This product is specifically designed for sinks and shower drains. It is generally not recommended for use in toilets, as toilet plumbing differs significantly.

What should I do if the unblocker doesn't work?

If the drain remains blocked after following the instructions, try a second application or consider using a plumbing snake. Persistent blockages may require professional plumbing assistance.

Is this product safe for all types of pipes?

While generally safe for standard indoor plumbing, it is best to consult the product label for specific material recommendations. Avoid use on incompatible materials.

How often should I use this product for maintenance?

For regular maintenance and to prevent future slow-draining issues, using the product monthly or as needed is recommended, following the light application guidelines on the label.

What safety precautions should I take?

Always wear protective gloves and eyewear. Ensure the area is well-ventilated. Keep out of reach of children and pets. Never mix with other cleaning products.

Troubleshooting

Drain remains slow after use

Ensure the recommended amount was used and allowed to sit for the full duration specified on the product label. For very stubborn or long-standing blockages, a second application may be required, or a plumbing snake may be necessary in conjunction.

Unpleasant odour during application

This is normal for concentrated drain unblockers. Ensure the area is well-ventilated by opening windows. Avoid prolonged inhalation of fumes.

Product splashes during pouring

Pour slowly and carefully directly into the drain opening. Use protective eyewear to prevent eye contact.
