more shower help

I was tinkering with my boat today, replacing fuel filter and changing ballast drain pump, so I decided to rip the shower apart as well. I wasn't getting much water flow. It was suggested to check all the lines, and I've done that now. There was some restriction on the hot side at the shower control, but now my problem is cold water pressure. I've checked all lines and all are good so i removed all hoses and watched water directly from where it T's from the system and it just sputters. It is t'd in just after the impeller. Is there a better place for it?

Maybe your shower pump is no good, or did you just replace it? Did you check you valve and shower assembly for plugs? It may be that quick disconnect on the shower hose. I would check very little stretch of hose and connections.

yeah, new pump. I took out all hoses and checked for blockage. Like I said, I just have little sputtering water pressure coming from where my cold line tees from my intake which is just after my water pump.
