Water Leak
1989 M22 on Chevy G30 chassis.

I have a substantial water leak that looks like it involves the fresh water tank. Depending on the slope, it leaks alternately on the left or right side. Took a quick gander underneath but find there is aluminum cladding that I would have to remove before I could inspect.

Anyone out there ever encountered this? If so, what advice or tips and tricks are you able to share?

Start at  your fresh water tank and work your way out via the pump, then the cold and hot systems, checking every potential leak point for leaks.  Do this with the tank full and the pump on.

There has been a LOT of posting about how to spot a leak using toilet paper or paper towels.

When you find the leak, then you can figure out how to fix it.

To add to what Kenneth said:

While a pipe itself can leak, the weak points are always where there is a fitting (an elbow, coupler, etc. rather than a straight pipe).

As others have said with any leak water can travel a ways inside roofs walls and flooring before it is visible so following the pipe lines is the best way to find the leak.

Although a tank can develop a crack, more likely the leak is at the pump supply fitting at the tank, which should be accessible under some panel. If you have done any drilling in the vicinity of the tank, a hole in the tank could result. Has been known to happen to careless individuals...

Fortunately no drilling.

Always a process of elimination right?
