After a torrential rain last night, I observed our sump pump work very
That pump is old, its age is unknown to me (leftover from previous
I think that I would like to upgrade it to the most reliable and
powerful pump generally available. My sump hole is 16 inches wide.
Any suggestions? I am looking for something like 3/4 HP.
For better or worse, here's the pump that I bought for $93. I hope
(based on a conversation with the seller) that this pump never saw

Yes, thank you. I have some specs pasted at the bottom also. I want to
say BIG THANKS to all people who suggested buying Zoeller. I hope that
the pump arrives soon in described condition. The seller lives not too
far from me (like 80 miles)
site. In fact, I now have two. One older one in reserve.
Murphy's Law predicts that sump pumps will only go out right after a
big rainstorm and just after noon on Saturday when the nearest pump
and replacement parts shop that handles Zoeller equipment closes for
Before I bought the second pump I used to keep an extra replacement
switch kit handy. If the switch mechanism is the same for the 1/2 HP
as for the 1/3, then you may want to see if you can puchase a
replacement switch. It seems I get about 6-8 years on a switch before
it goes bad. The replacement is pretty straightforward. The motor
seems to last forever.

Sounds not so nice, why would the switches last so little? Could they
have fixed whatever was the problem with switches? I will try to call
Zoeller again when I get the pump (with serial number) and will try to
see if they improved their switches any.
I received the pump today.
It is in a never used condition, quite obviously. It seems to work
when I engage the float. Very heavy and has a well made feel to it.
One thing that I did not like was a VERY short power cable, about 2.5

My well/pump guy would laugh at your recommendation for Zoller and also
for Flotec..He'd call them "consumer grade" crap..Sold exclusively at
Now try the Hydromatic line "industrial grade" from Pentair for a real
I find the most important thing to do is run the pump for a minute or
so every few months. If the pump sits for many months and you have no
water and it does not run at all, the bearings tend to seize up. If
you manually move the float to start the pump, you will keep the
bearings from seizing...
