I am disappointed with water pressure in the water system. It seems very weak. I'm convinced that the pipe diameters from the two tanks are too small and the 90 degree fittings make it worse. My experience on my previous boat is that the problem originates when the pump can't draw enough water and the supply side is the most important place to improve. I want to replace the 15 mm PEX supply lines and put in 3/4" and eliminate fittings (there seems to be an abundance of fittings where the 2 lines converge, with valves, just before feeding the pump. Has anybody had he same experience? Is the weak pressure built in on purpose as a water-saving device. To me, it's just frustrating. It seems that feeding new water distribution lines from the tanks to the pump is going to be a monumental task, if not impossible.
