What exactly do you want to test? If they will hold water with out leaking? If the pump will push water up to the tank? If the overflows will keep up with the pump?
Really all the above. First time for this type of setup. Anyway, I got the water in and the pump is running. Water level in the filter is staying constant and there is room in the filter to contain the water if the pump is shut down ... I tried that.
I guess I am happy it is all working. I think I will sit something under the main pump to quit the little vibration sound I am getting.
Now I have to get everything else in and let it cycle.
Still have not decided on my LR
dilemma. Not sure what we will do on that ...
