Blocked drains in your home can be a significant inconvenience. If you have a blocked drain, it’s important to know what’s causing the problem and how to fix it, and an experienced plumber can assist in restoring your pipes to proper working order. Here are some common causes of blocked drains and the steps you can take to fix the problem.

Tree Roots

Tree roots are a common cause of blocked drains. Cracked or weak pipes can be easily penetrated by tree roots. A plumber will use a drain camera to clearly identify the problem and repair it using a jet rodding machine. If your drain needs repair, your pipe may need to be excavated and re-laid. The best prevention for this issue is removing the problematic tree, but sometimes this just isn’t possible and you may need annual servicing.

Fats and Food

Fats and food quickly build up in pipes, especially during colder months. Fats can solidify and combine with wipes and solids to become a larger mass. To prevent your drains from blocking due to the accumulation of fats and foods, make sure you always allow your fats and oils to solidify before throwing them and your food scraps in the bin. If you suspect food and fats are blocking your drain, you can try pouring boiling water and detergent down to dislodge the fat, or use a mixture of bi-carb soda and vinegar.


Wipes, such as baby wipes, should never be flushed down the toilet. If you do use wipes or paper towels, it’s crucial you bin them and don’t flush them. These products absorb water, and can quickly block your toilet or drain.


A build-up of hair, shampoo and conditioner can easily cause shower blockages. A drain cleaner incorporating sulfuric acid, or a sani-snake, will dissolve your drain blockage. Prevention is key, and you can avoid blockages by throwing any strands of hair in the bin, or by incorporating a shower hair strainer.
