Buying Guide
Most taps cannot do the one thing you occasionally need them to do: point somewhere else. Washing a dog, rinsing hair, cleaning the sink itself, filling a bucket that will not fit under the spout.
This kit adds a hose and a spray head to a tap that never had one, and it does it without a plumber because of a single component.
The diverter is the whole product
Unscrew the aerator from the end of your tap. That is the mesh insert that softens the flow, and on most taps it comes out by hand.
The diverter valve goes in its place. Your tap then behaves exactly as it did before, until you flip the switch on the diverter and send the water to the sprayer instead.
That is why "mounts in minutes without tools" is a fair claim on this product rather than marketing. You are swapping one screwed-in part for another.
Check your tap before you order
Tap threads are not as standardised as you would hope.
The two cases that cause trouble are recessed aerators, which sit inside the spout and need the little key that came with the tap, and designer spouts that use a proprietary insert instead of a standard thread.
The supplier's own advice is to check the aerator thread, or measure the connected hose, before buying. Worth doing.
What it is made of
Stainless steel, brass and PVC, finished in silver.
The brass thread connector is the part that matters most. It is the joint that gets made and unmade, and the one under pressure. Plastic threads at that point are what strip.
The hose
Telescopic recoil, so it extends when pulled and retracts when released, plus a holder so the head has somewhere to sit rather than lying in the sink.
One piece of care worth following: let it hang when you put it away rather than coiling it tight. A permanent kink is where a hose eventually splits, and that is true of every hose in the house.
