4000 Litre Slimline Builder Packages

Slimline Rain Water Tank

Our 4000 litre tank is commonly used in areas where councils have requested a 3500 litre water tank. With very few 3500 slimline tanks available, the 4000 litre becomes the popular choice of builders, plumbers and architects. At just 810mm wide, it sits on wall and still gives enough space for a sidewalk when installed on the blind side of the house. The 4000 litre slimline water tank is popular for councils to specify for use as detention and retention tanks. ASC offers all size fiitings required for detention tanks and we can install your fittings for you as well.

Detention Fitting

Need a detention fitting? Not sure what a detenion fitting is? Read our blog about it here. We can fit your detention fitting for you when you order the additional fittings on your order. Just put in your order notes (at checkout) how much you need in detention and whether you want it intalled on the tank inlet end or opposite the inlet end. All too confusing? Don’t worry, we’ll call you to confirm your fitting locations prior to manufacturing and delivery.

Pump Options

We offer both single and double storey pump options based on your home.  For single storey homes, our standard pump is the proven ASC AJ50 Acquasaver Water Switch Pump, and the ASC AJ60 Acquasaver Water Switch Pump for double storey homes. Built on over a decade of experience and service, our ASC AJ50 and AJ60 pumps have been installed on thousands of new and existing homes all over Melbourne Adelaide and Sydney. We know our builders love them with their ease of installation and coupled with the most reliable mains water diverter, the Acquasaver ¾”. Upgrade to the AJ50BV and AJ60BV model as shown below to include barrel unions and shut off valves for easier installation as well as service and maintenance. The barrel union allows you to turn the fittings into the direction you require. If you are looking for a quieter pump, upgrade to the ASC AM50 or ASC AM80. The AM50 and AM80 is a multistage pump that is much quieter than your traditional JET pump. The ASC AM50 and ASC AM80 also come with an all stainless steel wetend, including impellers and shaft. If you’re building close quarter townhouses and apartments, and nosie levels is a factor, then the AM50 and AM80 is the perfect upgrade for your next job. The ASC AM80 also offes a higher flow rate if you looking to use it to water gardens or run domestic spinklers.

Are you looking for a submersible pump solution? ASC offers two submersible pumps along with Acquasaver Water Switch. Our ASC AS85 and ASC AS95 pumps come with a 10m power cable. The Acquasaver devices inlcude a wall mount bracket for a clean installation that hides your water pump. Out of sight and and out of mind. Having a submersible pump is ideal in backyards and courtyards where space is minimal. Submersible waters pumps are also great in areas where you have pets. From chewing power cables to safety concerns, having the pump inside the tank and the power cable out of reach from your pets. this solutions is fast becoming more and more popular.
