“Our view is that you can only save water if the reduction of water used completes the same tarsk adequately in accordance with the customers complete satisfaction”. How to Save Water and this inexpensive example can be applied to every tap outlet throughout a building by using the Doustseat, Doustsave or our Doustflow valves and as Plumbers tell us, “at least the DOUST stuff works”. Shower with comfort and save water! “Any sufficiently advanced technology is indistinguishable from magic.” A.C.Clarke
The Doustsave range are not fixed flow controllers. Good practice or well-known accepted practice in any professional hydraulic design involves a STEP DOWN in pressure or flow prior to the delivery point of the sealing mechanism. Why, because if you STEP DOWN the flow rate on the high pressure side of the hydraulic valve as shown in the red circle with the Doustsave valve you achieve a great deal. In our case with the domestic household tap as shown, one of the overriding benefits is comfort. In line with our overall water saving policy.
With nearly all the other water saving devices on the market it is the case that they are usually fitted on a single outlet of the fitting. This results in water delivery at a single highly restricted outlet with poor mixing properties that delivers the water in considerable force to you the householder. The flow being restricted at the point of delivery often results in discomfort of use and it is often the case that the householder simply removes the device. In fact many plumbers simply remove these devices when they are being installed, as they are usually the ones that must bear the blunt in dealing with these types of complaints.
The force of the water while unpleasant is usually being discharged directly onto you through the air and not into a delivery fitting which also can greatly increase your maintenance costs. Our Guarantee To You We at Doust Plumbing Products with the Doustsave Valve will not pressurize the low pressure side of the tap or any fitting so that “O” rings will fail and they will in time usually unseen behind the fitting and usually behind a wall resulting in considerable amount of water damage.
