Let’s face it, a lot of people put stuff down their drains that they shouldn’t. Sometimes a blocked drain comes from tree roots or other obstructions.

If you need your drain unblocked or replaced, Pro Plumber is here to help…


What are some common problems with blocked drains?

Your Pro Plumbers deal with blocked drains multiple times a week. The good news is that this problem is a common one and we’re likely experienced (and fixed) any problem you might have with your drains. Here are some common problems we see:

  • Slow draining sewer or stormwater pipes 

  • Blocked Sinks 

  • Blocked Toilets 

  • Gurgling sounds from sinks or toilets 

  • Water coming up from the ground

  • Water seeping into basements or ground floor bathrooms/laundry

If you’re experiencing any of these problems with your drains, contact Pro Plumber for a free quote to get it fixed in no time. Scroll down and read through a bunch of helpful tips and insights into unblocking your drain and some of the issues you might experience.

Drain basics

Both sewer and stormwater drains take the waste or stormwater away from the home. Sewer water is taken to a sewer main, deep in the ground. Stormwater is usually taken to the street and exits to the curb and gutter. This is all usually done by gravity. The wastewater flows downhill to the sewer main – stormwater flows downhill to the street. 

How does a blocked drain get blocked?

There are three main reasons why drains get blocked.

1. Movement
The earth is constantly moving and because your pipework is underground, if the ground moves, then so does the pipework. This causes the pipework to crack or bend causing blockages.

2. Trees & Plants
If there are open joints in the pipework, trees and plant roots are another major cause of blockages. The roots seek out the moisture on the pipework and continue to grow, filling the pipes with a mass of roots. 

3. Foreign Objects
People put things down their drains that shouldn’t go down there all the time. From a build-up of hair over time to household items that are intended for rubbish bins as opposed to drainage systems.

What's involved in clearing a blocked drain?

If the pipework is full of wastewater, we usually start by sending a high-pressure jetting machine down. This will often clear some of the blockage. Some drains can be unblocked with the use of plungers, but this is often just a quick fix, as the source of the blockage can’t be properly determined unless we do further investigation with a waterproof camera. 

So, the majority of the time, we use our waterproof inspection camera to get a look at why the drain was blocked in the first place. This usually gives us enough information to work out a solution to ensure the blockage doesn’t happen again any time soon.

We may have to dig up roots or replace old pipework.

Leak Detection

Pro Plumber have expert leak detection technicians which means we find the source of the problem without having to dig or destroy anything.

Leaking Tap

That constant "drip, drip" sound! It's enough to drive anyone mad. Not only is it torture on the mind, it's also probably wasting a lot of water and costing you money.

Toilet Repair

No one likes a toilet that doesn't work. It makes things kind of awkward, especially when you have friends over. Impress your friends, get your toilet fixed.

Blocked Drain

We get it, blocked drains are annoying. It seems like the water still goes down the drain but it takes an eternity and, in the meantime, the slightest use means your sink, shower or toilet overflows.

Gas Plumbing

You know that saying, "cooking with gas"? It's popular for a reason. One of the best ways to cook, heat your home and produce hot water, is with gas. Pro Plumber installs but also repairs gas plumbing systems.

Hot Water

Who doesn't like hot water!? We're not saying a cold shower isn't required from time to time but we really appreciate hot water - especially in Winter. Also, it helps clean things way better than just cold on its own.

Water Filter

Mmm clean water, free from nasties that upset tummies and leave you on the toilet for hours. You'll also save the environment and the hit to your hip pocket when you don't have to buy plastic bottles.

Gutters & Downpipes

Properly running, leaf-free gutters and downpipes are such a wondrous thing to us plumbers. This ensures the water flows away from your property or into a rainwater tank for later use. It's also safer in bushfire season.


Cracks in roof tiles suck in a big way. It's one of those things you don't notice until it's too late and the damage has been done. Lucky your Pro Plumber has plenty of experience with this kind of thing and can sort it out in no time.

Rising Damp

Yuck! Not only does rising damp make for a very sick house and inhabitants, if left for too long it can become a very costly problem to fix. It's best to get onto this before you have to sell a kidney to save your house.

Pipe Repair

There's nothing more satisfying for a Pro Plumber than repairing an existing pipe and saving our customers money they might have otherwise been encouraged to spend by someone suggesting entirely new pipes.


You know the coolest thing? Being able to water your garden without having to lift a finger! Even better, is controlling it with your phone. Ask us how we can automate your watering system.

Subsoil Drainage

Keeping water away from your house, especially under it, is actually way more important to the health and safety of a property than most people think. It's a dirty job but someone's gotta do it.

Annual Inspection

Preventing problems BEFORE they occur is the name of the game here. If you sign up to our annual inspection program, we can keep on top of issues before they become costly.

Rainwater Harvesting

Rainwater tanks are compulsory for all new home builds and there are two main reasons why - they save us money and reduce the burden on the local water system and helping the environment.

Fixed, Same Day

We had water leaking throughout our bathroom. Chris, the Pro Plumber, came out for free and was able to work out where it was coming from within minutes. They fixed the problem and were done the same day.

Highly Recommended

I found Pro Plumber on Facebook and messaged them for a quote to renovate my bathroom. Chris was friendly, professional and did a great job. We’re really happy with the result and highly recommend Pro Plumber to all our friends and family now.

Clean, quick and no hassle

These guys are great! Can’t recommend them highly enough. Such nice people and get the job done properly. They’re clean, quick and no hassle to deal with. The best thing was, I knew exactly what the job would cost me before they did the work. Nice not to have any financial surprises. My last experience with a plumber was horrible. I’ll definitely use Pro Plumber again.

Fixed my blocked toilet

I called Chris from Pro Plumber for a quote to fix my blocked toilet. He was at our place the same afternoon and fixed the toilet in no time at all. He then offered a free inspection of the rest of my bathroom plumbing and found an issue with the drainage system. We booked in a return visit within days and he fixed that too. Such a great service and not as expensive as I thought it would be.
