Expected Delivery on - .
DESCRIPTION
What it is
The Claber Hydro-4 BT is a sealed valve box with four solenoid-valve outlets and a built-in Bluetooth timer. It turns one water supply into four separately timed zones, for lawns, borders, drip lines and pots, in gardens up to about 600m².
How it works
Connect your supply to the 3/4" inlet and run a pipe from each 3/4" outlet to a zone. Pair the unit with the myClaber app on your phone and set up to two programmes per zone, with up to 8 watering cycles a day and run times from 1 minute to 2 hours. You can skip set days of the week, and use Water Budget to turn all the watering up or down (50–150%) as the weather changes. Bury it flush with the ground or fit it above ground. Plugs are supplied for any outlets you don't use.
Why it works well
- Each zone gets exactly the watering it needs the lawn, the pots and the veg beds can all run on different schedules.
- It runs on two AAA batteries, so you can fit it anywhere in the garden with no electrician.
- Add the Claber 90844 Bluetooth rain sensor and it skips watering after rain.
