HWH Hydraulic Leak - can't pinpoint the leak

[Dale777]

I have an HWH hydraulic leak that I can't pinpoint. It is coming from somewhere inside the HWH compartment behind the driver's side front wheel. The leak first appeared after I extended and retracted each of the front living room slides while I had the coach in storage; the jacks were not extended, since the storage area floor is completely level. Immediately afterwards, a large puddle of hydraulic fluid appeared on the storage area floor.

The problem is that I can't get my head or hands inside this HWH compartment enough to see or feel where the leak originates from. I do have access from the small HWH side door on the coach and a small removable panel to the HWH compartment from the basement, but this is not sufficient to see clearly what is happening. I've used a flashlight and taken pictures with a digital camera to try to see where the problem is, but I can't pinpoint it. There is clearly HWH fluid in the bottom of the pan that the HWH pump, manifold, and solenoids sit in.

Any suggestions on how to pinpoint this problem?

gotta clean the leak inside the compartment and then run the slide in/out. Its likely one of three things- the solenoid(s) for extend or/(and) retract, the hose connection(s) for the extend/(retract), or the plugs/fittings on top of the manifold. Many reports of the brass hex plugs on top w/missing or broken o-rings. If the leak is new, and its coming from the top, likely the o-ring(s) broke on the brass plug(s).
A mirror on an extendable handle (along w/the flashlight) works wonders for working in a dark, small cave like this. Sears has such on the shelf.
