Can this pump be installed externally? Or does it have to be submerged?

Actually, I don't think it has to be submerged. If you use it as the standard configuration (shown in the product picture) it will have to be submerged since the water has to come in through the grills/holes in the front. However, that cover (where the holes are) is detachable, and inside the cover there's a short pipe sticking out, to which you can probably connect a hose. If you put the other end of that intake hose in the water, I think the unit can probably stay outside of water. Well, you may need to make sure that pipe and intake hose connection is water tight, and the output hose connection - these connections won't really need to be perfectly water tight if the unit stays in the water.

The pump should be fully submerged -- it's quite small, but two inches might not be enough water, especially since the fountain causes quicker evaporation and you would need to keep it completely full at all times.

It has to be connected to the pump, it is not a stand alone,however it can be used in the pond or out.

Thank you for your question! The water should be about 4 inches deep to ensure that the pump is fully submerged.

I use it as a submerged pump. Very little noise because it's under the water. Good luck.

The pump is not submersible and is made of cast iron (would rust if paint is ever scratched off) so I would say no, it is not weatherproof.

It will not run unless submerged in water. If I remember correctly, it says that in the manual.

Yes, I have mine installed outside. It's a hard plastic shell with a metal bracket to attach to the wall. It's a very heavy duty system. Make sure to get the unit with the 1 inch outlets as it will not affect your water pressure at all. Overall I'm pleased with the units.

it has to be below the water or inline with the water source...it's not a self priming pumps!

It needs to be entirely submerged (except for the power chord). The instructions warn about letting the water get below the heating element which can cause damage.

This pump is not submersible. The motor and switch are not waterproof sealed. The pump is really designed to be placed or mounted on a flat dry surface

Must have an external pump. Filter works great. I would not recomend back washing. Works better if you take it apart and clean it that way.

You most likely have a leak in your plumbing somewhere allowing the entrainment of the air. Are you using the pump external or submerged?

No ... But you must have the proper psi downstream for the pump to work .. The psi is listed on the pump instructions ...

Can be outside, but to be prudent, I would shelter it from rain/snow. Mine is in a nearby, unheated garage. I used an old garden hose section to run from pump to manifold. Could be any length.

I have not fully submerged mine but I have sprayed it directly with the water hose and no issues so far

I'm not sure the unit is intended for external installation. Mine is under an inside sink. That having been said, the water connections are on the bottom. it seems to me that if you shut off the valve and unscrew the water connections, the water would with the help of gravity, drain out of the unit.
