Thanks for all the help. I have pretty much checked all of these options. Any ideas on a good replacement pump? I have a feeling the pump is the problems as when it runs and I have the hose on the discharge side disconnected, I can put my thumb over the pump discharge without much effort to hold the water back.

I have a Arits PDS1rv 25 water pump installed in my 2013 Tuscany. The pressure use to be decent but now is so low at all points that you can barely take a shower or flush a toilet. I have checked for leaks and obstructions and found none. Is there any adjustment on this pump or do I just need to replace it?
