The experiment: OpenSprinkler at the faucet

Because of the construction, you can OpenSprinkler Only use for switching solenoid valves. So you can't actually operate a "normal" faucet with it.

Or do they?

Idea: A solenoid valve has a standard 1″ screw connection, which is the same size as the “large” water connections. Adapters are also available at any hardware store.

So the idea: Let's connect a solenoid valve to the water tap!

PART 1: At the faucet

For this you need:
– Matching 3/4″ to 1″ adapter
– Solenoid valves IG or AG
– Double nipple 1″ AG/AG

IG means “internal thread” and AG “external thread”,

So that we don't completely block the water tap, I use a 1:2 adapter from Gardena here. Now all you have to do is screw on the adapters (the gray rings on the picture) and the solenoid valve (IG). So that you can now connect the hose below the solenoid valve, you need the double nipple 1″ AG/AG

Now just screw on the hose connection adapter and the solenoid valve is already installed:

Alternatively, you can do the whole thing with a solenoid valve AG. But then you have to install another connector between the water connection and the solenoid valve, eg a hose. I used a short piece of Gardena hose, professional version. The whole thing looks like this (left connection).

If the connectors are not tight, i.e. water runs out between the solenoid valve and the adapters, then you have to seal the thread with thread sealing tape (eg Teflon tape) or check any existing seals.

Part 2: Electrical connection

If the wire length of the solenoid valve is not up to the OpenSprinkler enough, then you should connect it with a suitable cable (see FAQ) and connect with a waterproof connector (e.g. 3M Scotchlok 314). At the OpenSprinkler/OSPI then connect the cable to COM and a zone port.

    Good day,

    I operate a water connection and 2 distributors made of brass, each with 4 water connections. 1 solenoid valve is connected to the main tap, which can be switched on via a power switch in the house.
    If I switch off the valve (power off) and the valve is defective and does not close, water could leak out unintentionally for a long time, right?
    Question: To be on the safe side, can you operate the connection with 2 valves on one switch and how does that work?
    Thank you in advance for your information!

      That's fine. Officially, no more than one solenoid valve should be connected to a zone, but since an output can switch up to 800mA, up to 3 solenoid valves can be operated in parallel (at 240mA per solenoid valve).

    The water flow should still be in the direction of the arrows on the valve bodies. In the pictures, however, they point in the direction of the 1:2 distributor input. So I think the valves are basically installed the wrong way round.

      Yes, well recognized! I noticed it too, but the pictures were already taken... So always pay attention to the correct installation direction!
