Why Your Adelaide Drains Keep Blocking Up

If your kitchen sink is draining slowly, your shower is pooling at your feet, or you're hearing gurgling from the pipes, you've likely got a blocked drain. It's one of the most common plumbing problems in Adelaide, and in most cases, the cause is predictable and fixable.

Here's what's going on and what you can do about it.

Quick Answer

• - The usual culprits are grease and fat, hair, tree roots, or old, deteriorated pipes
• - You can sometimes fix minor blockages yourself. But if the same drain keeps backing up, there's usually an underlying issue worth getting checked
• - A basic drain-clearing service typically starts at around $150. Jobs involving tree roots or pipe damage will cost more

Why Adelaide Homes Are More Prone to Drain Problems

Many Adelaide homes built between the 1950s and 1980s were plumbed with earthenware pipes made from clay or ceramic. These pipes were standard at the time, but decades later their joints crack, shift, or deteriorate, letting in tree roots and allowing debris to accumulate.

Many inner and southern suburbs also sit on reactive clay soils that expand and contract with seasonal moisture changes, gradually shifting pipe joints out of alignment.

Combined with Adelaide's established tree cover, it all adds up to a drainage environment that's harder on pipes than most.

What typically causes the problem:

• - Grease and fat buildup in kitchen drains, which solidifies as it cools and narrows the pipe over time
• - Hair and soap scum in bathroom and shower drains
• - Tree root intrusion into cracked or deteriorated pipe joints, common in yards with large established trees
• - Hard water mineral buildup coating the inside of pipes over time, which is more common in Adelaide due to the city's naturally high mineral content in tap water
• - Foreign objects flushed or washed down by mistake, including wet wipes, which do not break down like toilet paper
• - Collapsed or corroded pipes in older homes, where the earthenware has reached the end of its life

If the same spot keeps backing up, it's rarely just a matter of what went down the drain. There's usually something structural going on.

How to Clear a Blocked Drain Yourself

If you want to know how to clear a blocked drain without calling a plumber, these steps cover the basics:

1. Remove and clean the drain strainer or cover of any visible hair or debris
2. Scrape plates into the bin and wipe greasy pans before rinsing to reduce grease buildup in kitchen drains
3. Use a plunger with firm, steady pressure on bathroom or kitchen drains
4. Try a store-bought drain cleaner for minor blockages, though use these sparingly on older pipes

When to Call a Blocked Drain Plumber

Get a licensed blocked drain plumber in Adelaide when you notice any of the following:

• - Multiple drains backing up at the same time (this usually points to a main sewer line issue)
• - A foul smell coming from indoor drains
• - Gurgling sounds after using any fixture
• - Your overflow relief gully (the external grated drain outside your home) is overflowing or the surrounding ground is damp
• - The same drain is backing up again within a few weeks of clearing it

A blocked-drain plumber in Adelaide can run a CCTV camera through the drain before doing anything else. That takes the guesswork out of it entirely and means any repair or clearing is targeted at what's actually causing the problem, not just what's visible at the surface.

For urgent issues, our emergency plumber in Adelaide is available for after-hours call-outs.

When Repeated Repairs Stop Making Sense

If your drains block every few months and your home is more than 30 or 40 years old, repeated clearing may not be the right long-term answer. In some cases, the earthenware pipe itself is too deteriorated to be worth repairing again and again.

At Mr Plumb Co, if an inspection reveals that the pipework is at the end of its life, we will recommend replacement rather than another short-term fix. Patching a failing system just delays the same problem. A proper replacement deals with it.

Other Plumbing Issues Worth Knowing About

In older homes, drains are rarely the only issue. If you have noticed changes with your hot water, it is worth reading about the signs your hot water system needs a repair, or understanding your options around hot water system repair in Adelaide, before a small issue grows.
