I'm trying to figure out if my water pump inlet is not deep enough in my fresh water tank or if the level indicators for all the tanks (black, grey, fresh) are not accurate.
My pump will not be able to draw water and will run continuously with the fresh tank level reading at 1/3 full(can't get the pressure to 40 psi to shut off). I was thinking the inlet is not deep enough, but now I'm wondering if the sensors are not reading correctly. For example, when I drain the black tank, I can never get it to read "empty". It always says "1/3". Same for the Fresh tank, unless I open the bottom drain valve.
Does anybody know how to find the tank level sensors and the tank inlet for the pump?
