Delta High Volume Chamber
Easily divert large volumes of first flush with the Delta High Volume Chamber. Using multiple 100mm pipes to create the diversion chamber, the Delta’s revolutionary design makes installation simple. The Delta chamber is customizable up to 2 metres. Every 1m of Delta chamber = 73 litres of diversion.
Integrated Ball and Seat
This unique design ensure that the first flush ball remains close to the seat, even in high flow events, ensuring the diverter seals as soon as the chamber is full. No more lost balls when cleaning your outlet either!
Divert Larger Volumes
By allowing you to determine the frequency of first flush, the Advanced Release Valve ensures that the Delta’s first flush diversion is optimized. The transparent, rapid release exit funnel reduces build up and blockages while allowing for easy
Why Use First Flush Diverters?
Using a first flush diverter improves water quality and reduce tank maintenance by preventing the first flush of water, which may contain roof contaminants (such as sediment, bird droppings, spiders, insects, mosquito eggs and debris), from entering the tank. They help ensure cleaner water is available for use, which protects rainwater pumps and internal appliances.

We strive to provide you with a smooth and easy buying experience from order to delivery.
Here are some kind words from happy customers:
Thanks for the excellent customer service, especially that the order wasn't a straight forward one. I'd highly recommend you guys if someone asked about tanks, particularly stainless steel ones.
Great Service - Very commutative throughout the whole. However best for us, was the flexibility to work around our plumber. We changed delivery dates three times and they were easy to work with and even worked with our plumber direct, as a result tank delivered and fitted all the same day.
Fantastic price, customer service & product! We bought a QTank poly-slimline tank via Tank Shop, for our pool/garden. The customer service, delivery and quality of the product was fantastic. We’ve had a lot of trades & deliveries during our renovations and the experience with QTank and Tank Shop was one of the best. They were quick to confirm everything, kept us informed throughout and the QTank delivery was super smooth and well explained. Would highly recommend both companies.
No worries at all Tank shop were simply great.
Lotsa detailed help.
Careful and effective.
Actually surprisingly cheap for stainless.
Beautiful tank, I mean real pretty.
Delivery bloke was superb, even helping me with getting around a tight corner I should have had ready, with only positivity.
Oh and only a week and a half from order to install. This is not usual, but still, it happened.
Couldn’t be happier. It even rained after the install.
Great service Tank Shop staff were excellent to deal with and found a great solution for my installation. Price was good, service was great and I was kept informed of where my order was up to every step of the way. Delivery was right on time and the guys installing the tanks were very good. Highly recommend Tank Shop to anyone!
The process throughout has gone very smoothly - from the excellent information provided by you guys before and during the order process, through to the frequent updates and punctual delivery by Kingspan.
It's been a great experience - I will be happily recommending you to any of my colleagues who are looking for a tank.
Thanks for all your help!
Very happy and pleased with service, reliability and generous assistance. Have recommended Tank Shop to friends already. Thank you, Scott, for a very good experience you provided for us, your generous assistance at any time, your reliability and very good service.

Great product (Maelstrom Filter System), has made a big difference
Excellent service and value for money - Reviewed at least five tank suppliers and then found Tank Shop offering excellent deal on Qtank. Helpful and courteous dealing with both companies to get delivery tied in with other work being done. Highly recommend Tank Shop and their Qtank supplier for all aspects of purchase including delivery.
Had to get a new water tank and found this Brisbane based company online. The tank was ordered easily using the online form and payment system. The company communicated with us at every step, and delivery was definitely in the time frame they advised. The delivery guys were polite and efficient. Def recommend this company.
Got 3 tanks and 3 Maelstrom filter in 2020 in Melbourne. Very happy with kind and honest service & quick reply from Scott. Thanks
Good communication with Tank Shop made for an easy transaction. My new high quality rainwater tank and fittings arrived on schedule and the delivery driver had the tank sited in a matter of minutes. A very satisfied customer!
Excellent customer service over and above the expectation. Professional and prompt Ordering through to Delivery, Keith even helped us position the tank in which was a tricky spot. I had also initially made an error with the online payment and sent the money to a wrong Account, Scott was very helpful and we tracked the funds through Scott's Bank, CUA, no thanks to my Bank the NAB! All in all an excellent outcome, thanks Tank Shop.
My first time using Tankshop, and it all went extremely well very satisfied with pricing, quality and speedy delivery. Would recommend this seller anyone.
I ordered a $20 item plus transport from Tank Shop.
It arrived in Melbourne 2 days later and sat in the transport company’s warehouse for 2 weeks, waiting for delivery 15km away! Malessa at Tank Shop rang and emailed them each day of the second week, along with my emails to them to speed up delivery. Tank Shop offered a replacement item, sent by another transport company the day before the item arrived. Really? For the few dollars profit on my sale, Tank Shop’s customer service is like nothing I’ve experienced. Absolutely brilliant!! 12/10
Top equipment. Easy to buy and fast delivery. We keep coming back.
As I am in country NSW it was so easy to contact them, get the items I needed and the quick delivery.
I purchased a 5000l tank from the website. I had a follow up phone call that same day. Very happy with price and service received.
The Tank Shop was FANTASTIC to deal with!!!! I was VERY concerned about purchasing a tank online, so I called the number numerous times and asked 1000 questions, and the gentleman I spoke to was ALWAYS sooooo lovely and understanding of my concerns. Anyway we went with it and had our tank delivered PERFECTLY on time, with ALL the attachments we needed to make it all come together beautifully - SOOOOOO happy. I recommend you to EVERYONE! THANKS SOOOOO MUCH! WHAT CHEAP and FANTASTIC tanks!!!!
Purchased 10000L tank to take advantage of Council Rebate Scheme. Tank was delivered as arranged, driver was helpful with placing tank. Happy as Larry with the service.
