Doust Plumbing Products Pty Ltd

Welcome to Doust Plumbing Products
Doust Plumbing Products, the leaders in plumbing innovation, design and manufacture.
Established in 1999 by Philip Doust, Doust Plumbing Products started out in the family garage in Western Australia and has grown to become a reputable national company.

We have patented several premium plumbing products, such as the DoustValve™ and the RainWatch™ range of products. Our product range is a result of observations and experience within the industry, and an understanding of what actually works. In late 1998, The DoustValve™ was released into a competitive market, which was largely dominated by imports, but it quickly became a leading brand name throughout Australia.

Our tremendous success achieved in the marketplace is testimony to our belief that the customer is really the only person who controls the marketplace. We have also received tremendous support from many fine retailers and their staff. We believe, and our experience proves, that you are willing to support high quality, Australian-made products, and we thank you for our continuing success.

Our view is that you can only save water if the reduction of water used completes the same task adequately in accordance with the customer’s complete satisfaction.

“Any sufficiently advanced technology is indistinguishable from magic.” A.C. Clarke

Doust Plumbing Products is a West Australian based manufacturing company supplying premium tap parts to the international market.

Our patented products have innovative designs that are made with durable materials to enhance water saving.

Since its release in 1998, the DoustValve tap washer has achieved major sales results. Doust Plumbing Products receive many calls and letters as testimony to the advertised claims on the packaging. The main comments are “It’s so easy to turn on and off” and of course if you have a heavy-handed individual in your household, they can’t damage the DoustValve. The bladder just falls inside the protective outer housing, then the water pressure actually makes the seal. That’s drip-proof technology at work. This exclusive patented technology is only available in the DoustValve. The legendary endurance of DoustValve in high use or commercial installations makes having DoustValves installed in your own home a must.

There are many designs, but the DoustValve is the only compression tap washer in the world that you cannot damage by over-tightening. Positive proof, millions have been sold and exported by reputation around the world since its release in 1998. Therefore, millions of happy customers cannot be wrong.

What more the DoustValve tap washer is Australian, the DoustValve patents are held in Australia and of course it’s made in Australia. For more detailed information, obtain our free booklet at all leading hardware stores.

Why Doust Plumbing Products is considered the quality specialist in water-saving products
When you pick up a Doust product not many people know that we have developed state of the art manufacturing capacities, especially in quality control. In our factory often no one has actually touched the product, that is until the product has been inspected and packed.

The video on the right gives an insight into the internal workings of our factory.

Many of our so called simple products have been trialled over several years before we commit them to the marketplace. Our philosophy is that any product we manufacture has to represent value for our customers.

On all our products we have our phone number, our address and often we have a guarantee when others provide no guarantee.

And if you encounter a problem contact us either by email or phone as the Doust team is on hand to assist and advise you.
