Blocked drains are a common problem for homes and businesses across New Zealand. From slow-draining sinks to unpleasant smells and water backing up, drain blockages can quickly disrupt your day and lead to expensive repairs. At Grantham Hydro, we regularly help Kiwi households prevent drainage issues before they turn into major problems.
The good news is that most blocked drains can be avoided by following a few simple habits and scheduling regular maintenance.
Avoid Pouring Grease and Fat Down the Sink
Cooking grease, fats, and oils are one of the main causes of blocked kitchen drains in NZ homes. Although grease goes down the sink as a liquid, it cools and hardens inside the pipes, sticking to the pipe walls and trapping food scraps over time.
To prevent this, let the grease cool and dispose of it in the rubbish bin instead of the sink. Wiping greasy pans with a paper towel before washing them is another effective way to protect your drains.
Use Drain Strainers in Kitchens and Bathrooms
Drain strainers are an easy and affordable way to stop debris from entering your plumbing system. In the kitchen, they catch food scraps, while in bathrooms, they prevent hair and soap residue from building up in the pipes.
Hair is a common cause of blocked shower drains in New Zealand. Regularly cleaning your drain strainers can help keep water flowing freely and reduce the risk of blockages.
Dispose of Wipes and Hygiene Products Properly
Even products labelled “flushable” can cause serious drain problems. Wet wipes, paper towels, sanitary products, and nappies do not break down like toilet paper and often get stuck in pipes.
To protect your plumbing, only flush toilet paper down the toilet. All other items should be placed in the bin. This simple habit can prevent major drainage issues, especially in older NZ homes.
Be Mindful of What Goes Down the Drain
Food scraps, coffee grounds, eggshells, and fibrous materials like vegetable peels can all contribute to blocked drains. Even with a waste disposal unit, it’s best to limit what you allow down the sink.
Running hot water after washing dishes can help clear small residues, but it won’t prevent blockages caused by grease or solid waste.
Schedule Regular Drain Maintenance
One of the most effective ways to prevent blocked drains is regular professional maintenance. Routine inspections and cleaning help remove build-up before it becomes a serious issue.
Grantham Hydro recommends proactive drain care, particularly for older properties, rental homes, and commercial buildings. Regular maintenance can save money in the long term and extend the life of your plumbing system.
Watch for Early Warning Signs
Slow drainage, gurgling sounds, unpleasant odours, or water pooling around drains are early signs of a developing blockage. Addressing these issues early can prevent more severe damage and costly repairs.
If drainage problems keep coming back, it’s best to have your system checked by experienced professionals.
