Whirlpool bath

[arjones]

Hi all, hope there is someone that can help me out.
We have been doing renovations at our house.
About 6 months ago we had a whirlpool bath installed, and it is now tiled in.
Anyway we have moved in now, and gone to use the bath. It was only finally plumbed into the waste a couple of days ago.
Now we have gone to switch it on and there is water pouring out of this 5mm pipe.
This pipe is coming out of the large pipe running above the pump. It also has a little spring around the outside of the pipe? If that can help someone identify it.

I’ve been looking online for instructions but can’t find anything.
I can find instructions that describe that there is a 5mm pipe that goes from the button to the pump. I can also see this pipe, and it is securely plugged into the button and the pump. But I can’t find instructions regarding this second 5mm cable.

Does anyone know what this pipe is? And where it should go?

Current situation:
When I press the button the pump cones on and the whirlpool jets work. However as soon as I release the button it switches off.
And while the pump and jets are on the water is squirting out of this serving 5mm pipe.

If anyone can help it would be greatly appreciated

Many thanks

Can you get the installer back? Make and model would be handy if you want help unless someone is au fait with those types.
