The short answer is no thewater line run down through the floor there but there is no hatch to allow access to the water manifold in the wet bay below.
To access the manifold you have to remove the wet wall ( the one with all the valves) in the wet bay and pull it outwards it will be possible then to lay that wall face down to access the manifold which is attached to the back of that wall.
This is possible because the pex line have enough extra length and flexibility to get the movement you need.
Many of us here have reworked that wet wall be cutting it in half which allows it to come out easier.
Hope this helps
