Washer fluid saturating carpets in footwell

The passenger footwell carpet in my Disco has suddenly become saturated with windscreen washer fluid. I have taken up the carpets and the thick sponge underneath to find the footwells awash with the stuff. I have done a search and there is talk of a split pipe to the rear washer but I wonder if anyone else has had the same problem and can give me a clue what to look for please.

Washer pipe may be split up the. A post or above the rooflining, take the A post trim off & work the rear washer jet , you may see a nice waterfall down your A post

Thank you. I have a strong suspicion that is what it is. I will give it a go later and report back.

Took the side panel off and saw the fluid gently dripping from the wiring, traced it to the underneath of the washer bottle. Then filled the bottle up to a mark to see if was losing fluid, came back half an hour later and it had gone down considerably and the footwell filling up again. Disco has just recently come back from our local garage for a new rear wipe washer pump to be fitted. It's going back to the garage for them to sort it out.
