Dad don't want to spend the money to do a pit, etc. I explained the process to him. Honestly, at this point the whole basement (no one goes down there except for one room to do clothes) is a loss and will need totally redone. This has happen a few times in my lifetime but this is the most in this span of time. Last time was probably 15 yrs. ago. There are 3 rooms in basement and each has a low point so you can see the water collect at these points. If you don't catch it, you know what happens. This pump will be a band aid till I obtain the house and fix it correctly then.
Owned a house with a wet basement decades ago. We did three things, two of which you might already do - but maybe not:
1) Regrade the yard so that everything slopes away from the house. We added dirt, maybe 10-12" against the house and sloped out about 4' or so.
2) Extend all gutters to keep water well away from the house. Last few houses have had 3" PVC drains that take the gutter downspouts to the street.
3) Drain tile, pit and sump pump. Busted up 16" wide trench, dug 16" deep along the two problem walls. Put six inches of gravel, then four inch perforated drain tile sloped to the pit more gravel on top and re-poured the floor.
For a brand of pump - would check with my local supply house and see what they stand behind. Even within a brand name, there are better pumps within the line. You want only the best.. Knowing the damage caused by failure, the idea of a
primary pump with a secondary battery powered pump seems like a pretty reasonable thing.
