Thank you very much for the advice, I do have a good size pipewrench,
and a very large cresent too. I think it was replaced within the last
15 yrs if that makes a difference. It has a cracked housing due I
would guess from freezing? It is underground, in a well pit inside the
cottage, which is not heated at all in winter.

Adding to Joe's:

Tools. The crescent wrench will not be suitable. YOu need pipe
wrenches. It will probably take 2 and 24" size would be about right.

Pump type: Shallow well = one pipe down to the watger. Jet pump =
two pipes down to the water. The type currently installed should be
obvious on a quick inspection. The pumps in your link are jet type.

Once you change out the pump, you will then have to prime the new pump
installation so have some extra water on hand.
