What are the main causes of blocked drains?

Todays post is a simple one.

The main cause of over 85% of blocked drains  in Australia is tree roots!

Cooking fats, oils and grease, human and pet hair, sanitary products, facial tissues and napkins used instead of toilet paper, dental floss and broken or collapsed pipes make up the other 15% of blocked drains.

If you have repeat repeat repeat problems with your sewer pipes caused by tree roots then, this simple instruction found in the “head” or toilet of an ocean racing yacht, makes a lot of sense to me. I’m sure the yacht owners won’t mind if you put a similiar sign in your troubled bathroom.

Why we need a plan of our sewer pipes

Generally, when sewer pipes and drains are installed by a licensed plumber, they are inspected by an authorised person who draws a plan of the drainage installation showing where the drains run, what plumbing fixtures are connected and what, if any, other properties are connected!

In modern times, we have a self inspection system where the plumber draws the drainage installation and submits the drawing to the local water authority or council for their records.

Owners can get a copy of this diagram from their local water authority or council. If your property has a history of blocked drains or is surrounded by trees, I strongly suggest you have a copy of this drainage diagram and keep it in a safe and easliy accessible place.

Your local plumber can assist with getting a copy of this drainage diagram.

In NSW Australia, a drainage diagram is a standard inclusion in a Contract of Sale for any property. I suggest you look there first!

Who is responsible for these drains?

Blockages and problems with drains occur no matter what type of building you live in.

Most single or multiple level houses have their own drainage systems taking the discharge from all the plumbing fixtures within the property. The owner of this  property is responsible for the maintenance and upkeep of their pipes upto the point where his pipes join the council main.

Rows of terrace houses in inner city suburbs and semi-detached homes often drain into a “common sewer line”. These terrace rows can have upto 20 homes or more, draining into 1 common line. Depending on the fall of the land, this common sewer line may pass across the front or rear of the row and then  spill into a Boundary trap, before discharging into the Water authority’s main sewer line.

Generally, the common sewer line should be maintained by and costs associated with works or repairs on this  common sewer line should be borne by all parties on that common sewer line.

If blockages, repairs or pipe renewals are confined to the pipes and drains that take the discharge from any one particular house on the common sewer line, then those costs should be borne by that individual.

Any property owners connected to a common sewer line should be aware, that should a blockage occur in the common line, downstream of where he connects to the line, the sewer may surcharge or overflow in his yard or garden if it is the lowest open drain in the line.

This can be quite unpleasant if someone else’s sewer is coming up in your yard or even worse, your home!

When blockages occur, we recommend that all owners connected to a common sewer line communicate and co-operate with all other parties on this line .

Strata home unit blocks and Townhouses will have their own drainage lines that generally drain to a Boundary trap and then on to the Water Authority or Council sewer mains.

The responsibility for the maintenance and repairs of these drains is generally directed by a Strata Title Manager  and sometimes a Real Estate Property Manager

Commercial properties, Industrial Estates and Schools genarally all have there own  drainage lines that generally drain to a Boundary trap and then on to the Water Authority or Council sewer mains.

What is a blocked drain?

drain is an outlet where water can be piped away from a plumbing fixture like a toilet or WC, a basin, bath or shower, a kitchen sink, laundry tubs or an external drain, known as a gully.

Stormwater drains can take discharge from roofing guttering and pits and grates installed to take runoff  water collected from hard surfaces.

 

A blocked drain is usually referred to when waste water accumulates around any of the drains indicated and can not be evacuated from this place.

Most drains run to either sewer or stormwater mains that are assets of Water authorities, municipal councils and the cities and towns across the country

Most blockages are generally caused by tree roots, grease, hair, sanitary products, dirt and debris or a multitude of foreign items, even broken pipes.

Blocked drains are the resposibility of the property owners.

This series of blog posts will be aimed at blocked drain basics.

We will discuss who owns the drains, how to maintain them, what you should and should not put in your drains and what to look out for if your drains are about to block up.

We will look inside pipes, show you a drainoscopy or pipe survey so you know what it’s like in the network of pipes under your homes and buildings.

I encourage your feedback, so please ask questions and we will answer them promptly!

Sewer snake is an Anaconda

Last week we removed this large tree root from a drain in Kingsford Sydney.

 In fact, it was a tree root anaconda, measuring 6.3 metres long and it had completely blocked the pipeline. After removing the tree root from the pipeline and carrying out a “Drainoscopy” to determine there was nothing else wrong, our client elected to have Vaporooter sewer root control applied to his pipeline.

He understands the Vaporooter Guarantee.

” If you have a blocked drain caused by tree roots after an application of Vaporooter, we will clear your blocked drain for free”

Now, will someone call a reptile handler and have this beast removed!

A tale of two drains

 These 2 sewer drain  pipes with their lids removed are taking the discharge from neighbouring properties. They are surrounded by different species of large trees. Tree roots are growing into the sewer pipe through the pipe joints

The drain on the left belongs to a client who, after many years of tree root blockages to her sewer pipes, grew tired of the sewer overflow running through her home.

The pipeline runs underneath her marble tiled entrance and the suggestion to renew the pipeline would mean excavating the black and white tiled floor. Matching the tiles would be difficult!

The drain on the right is as we found it. We told the owner about Vaporooter!

The images below show the inside of each pipe.

Guess which drain has had Vaporooter?

Protecting Your Pipes And Drains From Tree Roots

If you’ve ever had to deal with tree root blocking your plumbing, you know that it’s an experience that no one would want to have twice. Drain back up leads to health hazards and removing tree root blockages can be costly.

Many home and business owners attempt to prevent future root intrusion through pipe maintenance and preventative measures.

Much of the root removal process includes measures that protect your plumbing from roots growing back into your pipes. Defensive measures include chemicals or chemical foam that coats the inside of your plumbing with root killing herbicide such as Vaporooter.

Other methods of plumbing maintenance include routine pipe and joint replacement or a complete overhaul of your plumbing (known as relaying). This protective measure is considered undesirable because it’s a very expensive maintenance option.

Mechanical plumbing maintenance might include regular pulling or rodding, which clears root obstruction before it grows to completely block pipes. This sort of maintenance keeps tree roots and other obstruction at bay, but it’s not a complete protective measure.

Protecting you pipes could be as simple as regular chemical treatment of your plumbing system. Chemical powder, liquid or foam is applied to the pipe to reinforce plumbing and prohibit future tree root intrusion. However, many home and business owners are nervous about dumping chemicals down their plumbing.

The best preventive measures often include a combination of several maintenance techniques. For example, regular mechanical maintenance followed by chemical treatment is a popular way to support plumbing.

Even careful pipe maintenance may not be enough to keep tree roots out of your plumbing, epically if you have numerous tree roots growing near your underground pipes.

The best solution is one that’s discussed with, and executed by an experienced plumber. A good plumber will help you decide the management method that’s ideal for your plumbing needs, such as Vaporooter.

Tree Roots in Pipe And Drain Joints

So, how did the tree roots get into your plumbing in the first place?

Pipe Joints - Protect Them With Vaporooter

It’s possible that the three roots found their way in through a damaged pipe or a weak spot in your plumbing system. Most likely, they first infiltrated through pipe joints, which are one of the weakest spots in the drainage system.

The joint is the part of the plumbing system that connects one pipe to another. Tree roots seeking food and moisture will travel along a pipe until it finds a defective area that can be used to infiltrate the pipe.

Pipe joints are often made of one of three materials, rubber, cement or an unplasticized polymer material know as UPVC. Each kind of material has a different level of resistance to tree root intrusion.

Cement (or mortar) joints are not very stable, and lend to the exact ruptures and cracks that let tree roots right in.  Cement is unstable because it’s so rigid that any movement of the surrounding soil can cause it to fracture. Cement joints cannot be treated with root fighting chemicals because the chemicals can cause the cement to degrade. On the upside, if they don’t crack or degrade, cement joints offer good resistance to roots that would degrade other types of joints.

Rubber ring joints are both easy to install and flexible enough to withstand shifts in the surrounding soil. But, they are an easier material for the roots to penetrate. Rubber joint’s resistance to roots rests on factors such as the quality of the ring installation and chemical treatments to the material. For example, some manufactures treat the rubber rings with root fighting chemicals.

UPCV pipe joints are the plumbing joint superstars.  These plastic-like pipes offer huge resistance to root intrusion. They offer the same tree root resistance as undamaged cement joints and they can be treated with resistant chemicals like rubber joints.
