I would hold down the float, or the float switch arm, or unplug the
sump pump, and see how high the water rises when there is nothing to
stop it. Maybe it will only be an inch or two. If that is the case,
you can readjust the float switch an inch or two higher, and then the
pump won't run at all when the water level is the same as it is now.

My next door neigbhor's pump used to run a lot, and by raising the
float one inch, over the course of a month, it was cut in half

HOwever, the water might rise above the top of the sump so be
preparted to turn the pump on before that happens.

I think still a long time.

If it is the bearings that will fail first, I guess you could put your
fingers on the top center to see if they are warm, or hot, after
running for a while. You could listen to the sound the motor makes,
but I personally have no idea if these are the things that will
change, or if you will be able to notice them, or how long it takes to
go from just fine to not working at all.

My pump doesn't run much, but I'm on only the second pump in 28 years,
and the first one only wore out because it was a pedestal pump with a
steel or iron pipe holding up the motor. The pipe rusted through at
the water level. On the new pump, that part is plastic and I figure
that part will never wear out. I guess some day the motor will fail.

Yes. IN 28 years, my pump has only been not able to keep up once
following very heavy rains and while it was still raining.

Maybe. You might want to have something ready to channel the water
from the sump to the drain. Sandbags? Two rolls of carpet, one for
each side? Maybe just two pieces of foam, like the round foam people
stuff in cracks, only an inch high. I doubt the water level will
exceed an inch. I wish I had a drain like that.

Put a garden hose on the basement sink and run it to the drain, and
put the water on moderate and see how much the drain will handle.
Then increase the water to as high as it will go, and maybe the drain
will handle that too.

Until you're convinced your safe, you may want to put things on
palletees or something in the basement.

But as upset I was after my first mini-flood, I have had 10 more since
hten, never more than a quarter inch, and really all that gets ruined
are the boxes I put things in. And that only matters when the boxes
are special, like they have the name of the thing and a picture on the
outside, or when they are of a special size or shape.

I don't keep silk sweaters in a box on the basment floor. I keep a
box of transformers, one of motors, one of power supplies, several
boxes of scrap wood, and all that stuff dries out fine. But I'm tired
of looking for new boxes.

If you think flooding is still near, you might want to get a Basepump
(find it with google) or a battery powered backup electric pump. Each
about 300 dollars iirc.

 Sump Pump Question
I have a pedestal sump pump set in a fairly deep pit, roughly 30", and
it is time to replace the pump. Most squat pumps will turn on at very
low water levels, but mine starts when the pit is fully filled, and
stops when emptied, and I am looking to replicate this feature so that
it cycles less often. Do all pedestal pumps work this way? Would any
other type of sump pump work in the same way? (I hear that pedestal
pumps are noisier and I am open to other types that would be
quieter.) Any suggestions on types or brands? By the way, my
pedestal pump has a tethered float that is at the end of a rope.

If the diameter of the pit is large enough, you can get a float switch to
control a submersible pump. This would give you more flexibility than a
pressure switch as to turn on and off positions. Some companies like Zoeller
make submersible pumps with a tethered float switch as well, but wouldn't
give you the range of a pedestal pump

 Re: Sump Pump Question
CAUTION: Most pedestal pumps besides being very lightly and cheaply built,
are not much over 30" high themselves and in your situation of a deep pit, a
power outage could result in the open frame motor being underwater when the
power comes back on -- it has happened to me -- the pump actually turned on
and pumped out the water despite the motor being totally full of water --
but I don't recommend the practice, I have changed to a submersible pump.

Many pedestal pumps work on a two float system. The bottom float determines
the shut off level and the top float determines the turn on level and are
user adjustable to suit your needs.

Most submergible pumps have either a fixed on/off level or some have a
mercury type switch on the end of a power cord, this can be adjusted by
lengthening the cord providing there is enough clearance to prevent it from
hanging up on the edge of the sump pit.

 Re: Sump Pump Question
I don't think a submersible pump with a tethered mercury float will
work, but I could be wrong. The ones I have seen at Home Depot can't
be lengthened long enough to reach the top of my pit; they would short
cycle as the water rises halfway up the pit. Besides, I would bet
that the float would snag on something on the way up or the way down
if it could reach the top of the pit.

By the way, thinking a little more about my current system, I don't
exactly have a pedestal pump, but rather some sort of hybrid system
with a submersed pump with a float tethered to a separate switch
assembly that is clamped to the discharge pipe that rises out of the
pit. I was thinking that a pedestal pump would handle the deepness of
the pit, but maybe a submersible with an appropriate switch system is
the way to go.

And just another idea, I suppose that since the pump is what I really
want to switch out, I could keep the existing switch system and plug
the new pump into it. Do they make a pump that relies on a non-built
in switch?

you said:
.....mine starts when the pit is fully filled, and
stops when emptied, and I am looking to replicate this feature so that
it cycles less often.....

if the present pump comes on when the sump is full and off when it is
empty, then it already is cycling as less often as possible. If it
came on any sooner or switched off any sooner, then it would cycle
MORE often. If you REALLY want it to cycle less often, you need to
make the sump bigger.
