Like I said, I am no pool expert but I played one on TV once.

When we ordered our pool installation the contractor originally wanted
to put the pump, filter and heat pump in a location near the pool that
would be noisy, very visible and would detract from the whole cabana and
landscaping work. I argued to install them behind the cabana, out of
sight and where they wouldn't be heard. The pool contractor balked,
stating that the pump manufacturer (Hayward) did not recommend placing
the equipment that far away from the pool and would not warranty their
performance. The whole project came to a halt.

I researched the pumps available from Hayward and taught myself to do
all the conductance calculations to determine water piping diameters,
manifolding and valving. I then found a Hayward "SuperPump" in their
catalog that met all the performance criteria for the conductance
calculations. I submitted all the data to the pool contractor who
forwarded them to Hayward. Hayward responded within a week giving a
thumbs up to the design and our preferred location of the equipment and
stated that a full warranty would apply.

Contractors sometimes try to take the easy route.

Contractors want to build the same cookie cutter pool they put
everywhere else. I had the Centex guys design my pool, then I started
looking at design criteria on a few web sites (calculating head etc)

I was able to use a smaller pump, farther away, simply by changing the
path and pipe sizes.
I used 3" right up to the 2" loop that runs around the pool (instead
of a single pipe). I kept all of the runs as straight as I could and
when I was done, the guy from the pool company was simply amazed at
what the pressure and vacuum side were.
I was able to turn my pool over with a 1hp pump as fast as he planned
with a 1.5HP pump and the equipment is 30 feet farther away. (behind
the garage)
I used a lot more and bigger pipe than they would have but I got that
money back in electric savings in the first year.

No comment. Don't want to start another endless pool design discussion.
