Question about pump for 4,000 gal pond
I have a strong preference for submersable pumps. There are less issues with priming and your not sucking the water up to the pump since the pump is actualy in the water. Now if you have qa raised pond and the or the external pump is located below the water surface that might be another issue. The other thing is with the submersable pumps they are extremly quiet.
