Maybe I need a bigger sump pump, so at the Ace Hardware, I looked at
the boxes.

If I get a Wayne pump, I can get a

1/3 HP that pumps 3800 GPH, or a
1/2 HP " " 4200 GPH, or a
3/4 HP " " 4500 GPH.

With ACE brand, I can get a
1/3 HP that pumps 3300 GPH, or a
1/2 HP " " 3600 GPH,
and maybe they make a 1/2 HP but I didn't see it.

So a 50% increase in the power of the motor yields only about a 10%
increase in GPH. The next 50% yields a 7% increase with Wayne.

With ACE, 50% increase yields a 9% increase in GPH.

Why is this?

Once in the 31 years I've been here I've needed a bigger pump --
because the pump was working full blast and still couldn't keep up
with the water coming into the sump from outside** -- and 3 of these
pumps are bigger than my current 1/3 HP, but i'm discouraged from
buying anything if I'm going to get so little increase.

**It just caused wet boxes (cardboard cartons) in the laundry room,
for the nth time, and I don't even do anything anymore when this
happens, but I would still like to have eveything working "right".

Add an additional pump to what you have.
