WaterTwo fitting instructions

A straight section of waste pipe 250 mm/10 ins long and clear of any connections is needed to fit a WATER TWO valve.

Mark the centre of a 250 mm length of waste pipe, mark 60 mm each side then cut out a 120 mm section of pipe and smooth the two ends.

Provided with the valve are three pairs of adapters, choose the pair that fits your pipe and slide one each side of the gap onto the pipe, remembering that they slide back onto the valve so they have to be fitted with the largest hole towards the valve.

Place the valve into the gap, remembering that the water flows into the single pipe and out of either of the two outlets, slide back onto the valve the two adapters to hold it in place whilst you mark out the position of the three securing lugs on the base of the valve. Dismantle the valve and drill three holes to a depth of 44 mm, using a 7 mm masonry drill then plug with the plugs provided, Offer the valve into the gap and slide the adapters onto the valve to hold it whilst you secure it with the screws provided.

DO NOT OVER TIGHTEN

Slide the adapters off the valve and apply adhesive or silicone to the last 40 mm of pipe and onto the shoulder of the valve, sliding the adapter back onto the valve taking care to make a watertight joint, repeat with the other side.

It should be remembered that the pressure is not as high as mains water therefore if you are using non standard pipes, any gaps can be taken up with tape or cord and then sealed with adhesive or silicone sealant.

WARNING EXCESS ADHESIVE MUST BE CLEANED OFF, ESPECIALLY NEAR TO THE ROTATING TOP OF THE VALVE

Below and in direct line of the valve, 300 mm away, drill and plug as before then screw in a vine eye. Directly below this at control height repeat with the other vine eye. Finally cut the cord in half, tie a large knot in one end and thread through a lug on the valve, through the two vine eyes, through a handle and finish with another knot. Repeat with the second cord.

A length of 19 mm / 3/4 inch garden hose is fitted to the valve and ends inside (and near the bottom of) your water butt allowing the newly diverted grey water to mix completely with the contents of the water butt. Allow water to cool before using it on the garden.
