2006 Dolphin water leaks

[Ray425]

Somehow I didn't get all of the water flushed from the lines and I now have a problem. How do I get access to the water lines that are on or past the fresh water tank?. I took the water inlet panel mostly off and can see that the leaks are not in the attached fittings. The leaks are from the water pump and somewhere else. I have not been able to find any access from inside. can anyone help?

Thanks, Ray
