What Our Clients Say
I am proud to supply this feedback as it has been a long time since I was treated so amazingly well as a customer until I dealt with Polymaster. A) received excellent Pre Sales & Service from your dealer, Martha at Electel. B) Then 10 days before delivery I received a positive call from a polite young lady who ran through the complete scope of the order. To say I was appreciative was an understatement. Wished more companies had your service commitment / DNA. C) Then a day before delivery I received a polite phone call from a truck driver who introduced himself as your driver and ran through the logistics / offloading etc. Said he couldn’t give me an exact time but would ring me in morning to advise exact ETA. I have never met a truck driver who was so organised. All of the above culminated in to me being blown away with Polymaster’s outstanding customer service. Thank you very much and please pass my feedback onto your Mgr Director. It was a pleasure to deal with a company who is so transparent and organised, congrats.
From entering details online and then talking with Tony Columbro to ensure I had details correct to then the text messages when the tank was ready. Then notified it was loaded and on its way to its new home. The whole process was professional and super smooth. Love the tank.
Once tank was ordered it was confirmed and outlets checked . Delivery day was advised and driver was excellent . Great company to deal with.
Good communication from Polymaster and delivered without a problem. Very happy with the quality of Polymaster products too.
Thanks to the driver, Bruce for delivery to a spot made difficult by recent rain. Managed to get tanks to their right spots. Good effort!
Sales people were excellent in providing updates to delivery and delivery driver also keep me informed of delivery times and helpful with information regarding the tank.
Great customer service especially Rachel. Also the driver was extremely helpful and professional in his handling of his job. Tank arrived on time as promised. The only little thing is that the tank was not put on position but close for us to push it the the foundation. Definitely we will order our next tank from them. Just recommended my friend to buy from Polymaster.
Good price. Great communication. On time friendly delivery service. Brilliant. Oh and the product is second to none.
Very happy with the product, also very happy with all the text messages telling me how the production was going. Will definitely be buying another tank from you in the future.
Besides the delivery arriving a day early the entire experience was excellent. Tim was excellent and did everything possible to help out to make sure the tanks were put in the best place. Thanks very much."
Ecstatic with delivery made by Mark Sinclair today - haven't had good old service like this in a very long time. Mark was polite, helpful & an absolute bloody gem. Highly recommend Polymaster to everyone.

My experience was excellent. I don't know how it could be better. Everything worked exactly as I hoped.
The customer service was fantastic with a step by step walk through on the setup of the tanks. The recommendations on how to get the best set up of the tank fittings pump positioning. To the delivery of the tanks and the positioning on the ground.

Over the moon with the quality of the tanks and the service ????
Both truck drivers are excellent. Very helpful. All tanks are wonderful. Very quick delivery after placing order. Had phone calls from Polymaster to check tank details and progress of delivery.
"Great customer service from office, keeping me up to date with delivery time etc. Delivery man mark was on time, knowledgeable and did a fab job getting in a tight driveway. Very happy with my tank thank you."
First class service. First class product.
We’ve found working with Polymaster to be a positive experience. The quality of the products which we have used has been very high, and the willingness and technical capacity of the staff to tackle non-routine engineering modifications has given us confidence in the finished build.
The decision to sell Polymaster tanks to my customers is an easy one due to the fact that I strongly believe they are the best quality tanks on the market and I can confidently stand by the product I am supplying.
We are very pleased with the choice we made to go with Polymaster due to the quality and excellent service. We will endeavour to use more Polymaster tanks as we continue to upgrade our property.
Septic FAQ
What should you never put in a septic tank?
Never put oil, gasoline, paint thinners, solvents, photographic chemicals, weed or insect killers down the drain. They can poison your septic system and possibly threaten water supplies for your whole neighbourhood. Even latex paint is unhealthy for your septic system.
How long does it take for toilet paper to break down in a septic tank?
If you purchase toilet paper that is labeled septic safe it should dissolve completely within 20 minutes. You can test this yourself by taking your septic-safe toilet paper brand and scrunching it into a cup of water.
How often should you clean your septic tank?
Septic systems overtime will build up with an excess of accumulated solids that should be pumped out every 3-5 years. This will depend on the volume that is put through the tanks so varies greatly on application. Make sure the tank is pumped out by a licensed liquid waste contractor, please see the local council in your area about any special EPA regulations.
Warning - Never allow anyone at any time to enter the septic tank as it is a confined space and once operating is an extreme health risk.
Can I install a septic tank myself?
Unfortunately, a septic tank is a bit specialised, so you aren’t able to DIY this job. Septic tanks must be installed by a licensed plumber and then signed off by your local council authority. This will ensure your warranty is valid, and when you purchase a Polymaster Septic Tank your covered for 10 years.
Polymaster tanks are a one-piece moulded tank, they are lightweight and easy to handle. Lifting lugs are incorporated into the design to make it easy to lower into place. The forward thinking Polymaster engineers designed the septic tanks to minimise the amount of work required on site, these are pre-assembled before leaving the factory, so the plumber can simply position the tank and connect in and out flow pipes! The low profile and compact design minimises the amount of digging required prior to installation, the depth of excavation is minimised, and the hole is easier to backfill after installation. Saving the plumber time during the installation and you in cost.
How often do I have to empty a septic tank?
This depends on how much waste your household creates. Remember it is only solids that really build up. The Australian Department of Health recommends pumping tanks every 5 years however it depends how much solid waste is flushed into the tank. Pumping out the tank must be done by a licensed liquid waste contractor who can then take the waste to a processing facility. Your local council will be able to advise if there are any EPA regulations in your area.
IMPORTANT: Nobody should ever enter the Septic Tank – It is a confined space and once operating is a health risk
Polymaster septic tanks come with tamper-proof screws to make sure there are no dangers once the tank is installed and buried.What are the signs of a full septic tank? What happens if you never pump out your tank?
- Pooling water
- Slow drains
- Odours
- An overly healthy lawn around the tank
- Sewer backup
- Gurgling pipes
- Trouble flushing
How fast does a septic tank fill up?
This depends on how much waste your household produces. Most waste that comes out of a home is liquid with very little solid included. Thankfully this easily leaves the tank to either the municipal wastewater system if that is available or the drain field. The solid portion of waste takes a few years to build up. As mentioned previously, it is generally recommended to empty tanks every 5 years, but some people have reported up to 10 years between pump outs.
Does shower water go into the septic tank?
Regulations require that all water from inside the house go through a septic system, either on site or at a municipal treatment plant. This includes showers, toilets, laundry systems, kitchen and even swimming pools – because of the chemicals.
Water from roof gutters should be the only water leaving a property through the stormwater drains.
Once again, it is best to check your local council regulations for their recommendations in your area.
Should I choose a Plastic or Concrete Septic Tank?
Plastic or poly septic tanks dominate the market. They are far cheaper to manufacture, last longer and much easier to install. The delivery costs are also much cheaper, and they can travel long distances fairly economically compared to concrete tanks. On average concrete tanks only lasted around 10 years, whereas plastic septic tanks will last twenty to thirty years. Unlike concrete septic tanks, plastic tanks are not porous and so you will not get seepage of wastewater into your ground water or around your garden. For all these reasons, and more plastic septic tanks have become the industry standard today.
