I have a 16' x 32' x 9' deep pool. *I live in an area where in the day
electricity is double the cost than at night. However, running the
filtration system at night means lots of heat loss and water loss,
therefore, it's easier to keep the pool warmer and cleaner during the
day when electricity is the priciest.

Why does water loss occur if you run the filter at night? Why does heat loss?
You could insulate the pump , filter, and plumbing if it really makes any
difference.

* by moving the water during the

day, I can preserve and capture the sun's heat throughout the pool,
with minimal water loss under the solar cover.

I have a 90 degree elbow on a 1.5" ID pipe intake to the pump. *I have
no elbows on the outtake back to the pool on 1.5" ID pipe, but do have
1.25" barbs inside that outtake pipe.

Is it worth my while to take the 90 degree elbow out and use a flex
pipe to have a sweeping radius to increase water flow? *My filter is
running at 12 PSI under current setup, but it's rated for 50 PSI.

It's probably not going to make a measurable difference.



I want to know if there is a possible gpm increase by removing that
elbow. *If I can move more water in less than I can save on
electricity, or have the electricity being used now, move more water.

Anyone have any thots on this dumb theory?

Get a 2 speed or high efficiency pump and run it at low speed. That'll save you
far more.

Bob F covers all the important points....

A 2 speed pump will save way more money than an elbow replacement....
