Technical Windscreen wash- going

[Jolucy]

So my windscreen wash keeps going, I can see where I fill it it goes down gradually. Can't see any water under the car so not sure wherenit is going.
The front sprays fine but the back doesn't- nothing comes out

Where could the water be going?
Also is it costly

What the water could be in the boot?
How can I find the leak

 

[Jolucy]

So it turns out the passenger seat back floor is soaking wet so it is obviously leaking on way through
Now how to locate and fix

Take of the C pillar trim and start there.
