I’m troubleshooting the raw water system on a Next Gen 5.5kw and need a sanity check. For the pump pictured, which would be the inlet, and which is the outlet?
Thanks,
Brett
So many answers and methods but the first was the most obvious and simple.
If you look at how the impeller fins are against the constricted side of the housing you see that the impeller rotates clockwise looking from this side.
The water is picked up at the top hose and, because of the constriction bending the fins closed, is forced out at the bottom.
How long has it been sitting - could the heat exchanger be clogged?
My genny intake hose delaminated on the inside and closed off flow. Great idea to change intake hose regardless. Boy did that one drive me crazy for a while.While checking hoses, You might just as well change the inlet hose. Pumps work by creating a partial vacuum at the inlet then atmospheric pressure (14.7 psi at sea level) pushes the fluid into the pump. Its possible that you could have cut inside the hose that closes off the line when put under a vacuum. I've seen people pull off the hose and look through it and say its ok the reinstall and have it close as soon as the pump turns.

Oh, OK, I though he was asking what the inlet and outlet was .Simi, because he was getting no water throughput he was questioning whether or not the pump was put on correctly. Or whether it was 180 degrees off!
