Drainwave, Water Efficient Plumbing for the Future
Please note, all prices are subject to Vat
As water becomes scarcer and environmental factors lead to an increased need for low flush and low-flow water saving devices, pipes that take away waste water will get dryer so they will be more prone to get blocked by rubbish and debris and this is where the Drainwave comes in. It is simple to use and simple to install. All that you do is place it in-line with the waste water pipe flowing from a property. The waste water flows into a chamber within the product and is stored until it over-fills. At this time, a tipping bucket tips forward and allows a large flood of water to flow through the whole of the waste pipe, which sweeps any rubbish in the pipe before it. A normal straight connection from a house would not do this; The flow would just be along the base of the pipe and as the pipe is not filled fully, some rubbish can get trapped in the bends and junctions.
How does the Drainwave work?
The Drainwave collects black and grey water (eg. toilet, sink, shower, washing machine) via either one or both of its two inlet ports. The Drainwave temporarily retains this water and when a certain amount is collected (9.5 ltrs) a tipping bucket inside the Drainwave tips by gravity sending a pulse wave through the drainage pipes clearing any build-up and preventing blockages. It should also be used after the outlet from a sewage treatment tank as it has been proved that blockages are common, two to three metres from the tank.

What are the benefits?
- The Drainwave acts as a catalyst for water saving by allowing properties to achieve maximum water efficiency without risk of blockages. This potentially saves consumers considerable amounts of money as water metering systems are introduced throughout the country.
- One moving part, no external power required and little or no maintenance for the life of the product.
- Easy to install.
- 15 year manufacturer's guarantee.
- Full WRC and Waterwise approval.
- No additional cost for installations on new build.
- Can be retro-fitted into existing manholes.
- First product ever to take control of the drains.
- Facilitates the use of low water technology without compromising the performance of drainage systems.
- By facilitating water-saving, the Drainwave significantly reduces the amount of energy expended on catching, storing and transporting water, thereby reducing carbon emissions.
- The Drainwave can also be used for septic dosing application. The Drainwave provides a low cost, low maintenance solution, which delivers an extremely even measured dose to the whole pipe absorbtion network.
- The Drainwave releases waste water in one wave equivalent to a 9.5 litre flush. This carries waste solids significantly further than lower volume flushes. By installing the Drainwave this dramatically improved performance can be achieved without compromising on water-saving devices.

How many fixtures can be plumbed into the unit?
- the more fixtures that are plumbed into the unit the better as with more fixtures there is more water to contribute to drainline performance
- the unit is designed to have up to six toilets plumbed into it
- refer to the installation instructions
What should the householder do if they are going away for an extended period?
- if the toilet is not going to be used for an extended period, it is recommended that the owner flush the toilet so the Drainwave tips before leaving

Can the unit be affixed under the floor?
- Yes using standard pipe hanging fixtures
Can the unit be retrofitted?
- Yes
Is there any issue with respect to sewer blocks and back flows?
- No, the bucket should reactivate when flow resumes
Can the unit be used for dosing evaporation beds?
