General

The weight of our tanks alters depending on the size, number of welded fittings and the sg of the liquid they are designed to store as heavier liquids will require a heavier walled tank. However, they are comparable in weight to fibreglass or galvanised tanks.

The initial step is to have completed and approved drawings before products and equipment can be ordered and manufactured. This typically take around 3-4 weeks, therefore it is critical to approve drawings quickly in view of decreasing the lead time. The next step is to place your order and you will be looked after by a project manager who will deliver all aspects of the project in around 4 weeks.   When projects have set delivery dates we work with the client to achieve this from the beginning of the project.

Many different circumstances will determine when a tank needs replacing. These are;

  • Number of welded fittings
  • Type of chemical being stored
  • Whether a tank is bunded or otherwise
  • Exposure to other elements
Polymaster offer a 5-year warranty on all chemical tanks. In most cases these tanks will outlast this by many years however, replacement of chemical tanks needs to be addressed on a case by case basis and we recommend you speak to one of our technical team.

Yes – Polymaster tanks are fully UV resistant and are built for Australian weather conditions. Components are carefully selected to ensure that they are protected and resistant to the elements.

This is a common myth; the strength of the wall is based on the material (polyethylene) thickness and type of material selected. Both wall designs have similar strength, it’s only a case of aesthetics or preferred finish.

Our tanks are made from BPA free, food-grade polyethylene and certified to AS/NZS4020, the Australian Standard for drinking water, however Polymaster cannot guarantee the quality of the water in your tank due to your way it is harvested from your property.

Delivery

Every industrial tank is different, Contact the industrial team to ask questions about your delivery.

Our self-bunded tanks are always despatched on a pallet. This means that they can be unloaded with either a forklift or crane with spreader bar. It’s important that it is only lifted from underneath the tank unless there are purpose-built lift lugs welded on.   If larger tanks are to be lifted with a crane, specific purpose built lifting lugs must be welded onto the tank.   If the tanks are a bunded tank or have a separate roof screwed on, under no circumstances are the original tie down points to be used as lifting lugs.   Forecourt stations are to be lifted from the chassis using all the lifting lugs provided. A spreader bar or slings are required to prevent damage to the walls when the station is lifted. Never drag, lever or push the unit once the weight is resting on the base.

Yes, we can for a storage fee of $220 inc gst per tank per month.   Normally once the tanks have been made and fitted out according to your specifications it is invoiced and shipped.

When delivering our tanks to site, they need to be placed in a certain position/place on the customers property. To ensure we unload the tanks safely and to meet your needs, we may require some help on site. It is the purchaser’s responsibility to provide assistance with tank unloading and positioning. Following is a guide.   tank unloading details We endeavour to get it as close as possible to the pad, however it is ultimately the purchaser’s responsibility to position it perfectly.

Our tanks can be quite large making the trucks loads very high and long and we take the job of delivering your tank safety very seriously. Therefore, we have established clear guidelines for our deliveries.

  • The clearance required for truck and trailer is 19 metres long, 5 metres high and 3.5m wide.
  • Ensure there are no low-lying branches or powerlines
  • Make sure the gate/entrance is wide enough and there is enough turning area for the 19m long truck and trailer (size of a normal roundabout)
oversize truck

Our logistics department will be in contact with you 7 days prior to delivery to;

  • confirm your delivery address
  • preference for morning or afternoon delivery
  • advising access guidelines for delivery to your property
  • if you will be onsite when the delivery arrives
We can even offer a courtesy call before your delivery.

Installation

We do not recommend that you weld your own fittings as it will void the warranty and our staff are experienced and qualified in poly welding. Polyethylene welding needs surface preparation, compatible resin filler rods for welding and the appropriate fittings for the welding to be successful.

Yes, all Polymaster tanks have moulded lifting lugs that can be used when the tank is retaining its one-piece configuration. If the tank is a bunded or has had its roof removed for access reasons, then the lifting lugs will need to be welded onto the wall of the tank if required.

It can be quite normal for a tank to bulge, due to the properties of the polymer (plastic) used to mould the tank. We quality test our tanks to ensure they are manufactured within tolerances and stand behind our warranties. If you are still concerned, please take some photos and email them to our aftersales team on aftersales@polymaster.com.au

The foundation that your tank sits on is critical to ensure that it is supported adequately without the risk of causing fatigue to the tank and potential failure. To correctly install your rainwater tank, it must be placed on a firm, level and flat base, free from any rocks, stones and sharp edges. A concrete pad is recommended, however, a compacted sand base or other consolidated fill such as crusher dust is also suitable. The base must be thoroughly compacted and be exactly level and flat in all directions and should be 75-100mm deep and at least 600mm larger in diameter than the tank base. The outsides of the base must be supported by a retaining wall of some kind to ensure that no erosion can occur through washout, vermin or any other factor. Failure to provide a stable base will void the warranty.   It is important to check the base on an annual basis to ensure it hasn’t eroded, as this may affect the structure of the tanks. If the foundation is not concrete, it’s ideal to have a roof structure over the tank for drainage – Consult the Installation and Operation Manual of the manufacturer for more details. If you have a chemical tank the slab needs to be engineered to support the weight of the tank without flexing or breaking.

Polymaster tanks can have as many fittings as required by you. Standard tanks come with 1 x outlet, 1 x ball valve and 1 x inlet. So, any fittings required above this do incur additional charges. This is also the case with upgrading fittings. The standard fittings on the tank can be upgraded to any size you require. Additional charges will apply. Our outlets and ball valves can range from as small as 1” to 4”(25mm to 100mm).

Yes, you can if you have one of our smooth wall tanks.  Outlets can be fitted anywhere there is a smooth surface on the tank wall. This is not so straight-forward with our corrugated tanks. Each of these tanks have a ‘flat spot’ on the tank where the outlet can be fitted. There is one flat spot on each tank that is located at a specific location. The position of this flat spot varies according to the size of the tank. See below table for the location of the ‘flat spot’ on each tank.

All Polymaster tanks have standard fittings when purchased. These fittings vary slightly according to our different tank ranges. Our Premium Corrugated tanks and Slendastyle tanks come standard with:

  • Inlet with leaf screen/strainer
  • 1 x 90mm overflow
  • 1 x brass outlet
  • 1 x brass ball valve
Our Smooth Wall tanks and Polychoice slim tanks come standard with:
  • Inlet and leaf screen/strainer
  • 1 x 90mm overflow
  • 1 x brass outlet
The outlets and ball valves also can vary in size depending on the size of the tank:
  • 200ltr – 5,000ltr tanks = 1” (25mm) outlet & ball valve
  • 7,100ltr – 50,000ltr tanks = 1 ½” (40ml) outlet & ball vale
The brass outlet will always be fitted to the tank and fitted with the protection thread cap. The ball valve is supplied loose, unless specified otherwise. Other fittings are available upon request.

Each style and tank size have different available fitting positions. Therefore, refer to table below to find the fitting positions for your preferred tank. Premium Round Tanks:premium round tanks Polychoice Round Tanks: polychoice round tanks Slendastyle Tanks:slendastyle tanks Polychoice Slendastyle Tanks:polychoice slendastyle tanks

Yes, this is possible for Polymaster tanks, however they are not to be buried more than ¼ of the wall height. It is also imperative that when you partially bury a Polymaster tank, it is full of water at the time to ensure it stays in position. This reduces any risk of damage while burying it. It is best to then keep water in the tank after it has been partially buried for 4-5 weeks, to stop any movement of the tank. Ensure the water level doesn’t go below the ¼ of the wall height. If you want to fully bury a tank, you might want to consider our incredibly tough Underground Tank.

Technical

The stated volume of the tank is the amount of liquid a tank can hold before it flows out the overflow fitting.   The effective volume is dependent on what fittings are inserted, height off the base of tank and where you are drawing the liquid from, can be quite different. All tanks with a filling valve are not fitted beyond 95%.

The bund capacity varies between models, however all Polymaster tanks have a minimum 110% capacity.

Your bund alarm sensor needs to be checked as part of a regular maintenance schedule.

Yes – a common addition to tanks is a high/low level alarm. This addition enables the integration of an ultrasonic sensor and display, it incorporates High, low, Bund, High Alarms in one unit with output for SCADA or similar.

Most polyethylene tanks are suitable for holding diesel. Generally, it is how and where the diesel will be stored which determines what configuration of tank/s are used. The Australian Standard 1940 outlines what the requirements are.

Polyethylene tanks are designed to handle all atmospheric or ambient temperature. Initially these tanks are not designed to handle elevated temperatures. If you require the tank to store high temperature liquids, please get in contact with our technical team to discuss your needs.

There are over 1,935 chemicals that can be stored within a Polymaster tank, these include diesel, AdBlue, liquid fertiliser and many more. Our tanks are manufactured using Polyethylene (PE), which has great chemical resistance to most chemicals, they are suitable for a large variety of applications. Specific consultation and compliance/suitability of chemicals can be confirmed by our technical engineering team.

It can be quite normal for a tank to bulge, due to the properties of the polymer (plastic) used to mould the tank. We quality test our tanks to ensure they are manufactured within tolerances and stand behind our warranties. If you are still concerned, please take some photos and email them to our aftersales team on aftersales@polymaster.com.au

Warranty

All Polymaster warranties are on a pro-rata basis. Under this warranty, if your product fails before the end of the warranty period, it is replaced at a cost that depends on the age of the item at the time of failure.  This is calculated by the following formula:              $ maximum liability = A x B/C Where: A = Original purchase price B = No of years of the warranty period remaining C = Total warranty period For example: Tony purchases a tank for $2,000 and it comes with a 20-year warranty. It is now 15 years old and Tony would like to make a claim against his warranty. Purchase price x number of years remaining / divided by warranty period $2000 x 5 years divided by 20 = $500 Therefore, Tony has $500 allocated to repair or to replace the tank in the unlikelihood that something goes wrong.

We offer a 5-year warranty on all chemical tanks. In most cases these tanks will outlast this by many years however, replacement of chemical tanks needs to be addressed on a case by case basis and we recommend you speak to one of our technical team.

Our diesel ute packs have various components, all of which have a different warranty period.

  • The tank  – 2 years warranty from date of purchase
  • The hose – 3 months warranty from date of purchase
  • The nozzle – 3 months warranty from date of purchase
  • The pump –12 months warranty from date of purchase

All Polymaster troughs have a warranty period of 12 months from date of purchase.

Yes, we do, our range of tanks are manufactured with strength in mind. Therefore, we can offer our customers such a great warranty. Following are our warranties for the different tank ranges:

  • Certified Premium corrugated range – 20 years from date of purchase
  • Certified Smooth wall tanks – 15 years from date of purchase
  • Certified Slendastyle and Slendaline tanks – 10 years from date of purchase
  • Certified Polychoice slim tanks – 7 years from date of purchase
