It may go weeks before it trips the installer said basically the same thing
that Clare said he will replace it with a standard outlet after the inspection


Removing a safety feature is not a good idea and of course a code violation. Get someone who is qualified to work on electrical wiring as your installer does not have a good attitude and is setting himself up for possible liability if someone got hurt or died from using a non-GFCI receptacle. Would you want a family member to plug into that unprotected outlet?

The only legal out is a 240v pump in a 6-15 or hard wiring the 120v
pump.

Or a 12 volt pump or a medical grade isolation transformer


12v would work but the wall wart would be on a GFCI.
Isolation transformers are not a fix for anything in the code.
They still must have a grounded conductor if you use a chapter 3
wiring method on the secondary (unless it is part of a listed
assembly).


The wall wart on a gfci powering the pump won't trip the GFCI An
isolation transformer constitutes a seperately derived power source
and a "medical grade" isolation trasformer has zero leakage It can be
grounded with no effect on the GFCI because the GFCI compares line to
neutral - it does not measure ground current. The isolation
transformer removes the ground reference from the neutral so there is
no shock danger from either line or neutral (now technically l1 and
l2) and ground

.
Or some
inspectors will accept a single 15 amp twist-lock outlet - making it a
"dedicated" outlet for a single use. - equivalent to a "hard wired"
device..


Not for the last couple cycles.

Here in ontario they still did a couple years ago

"210.8 Ground-Fault Circuit-Interrupter Protection for
Personnel. Ground-fault circuit-interrupter protection for
personnel shall be provided as required in 21O.8(A) through
(C). The ground-fault circuit-interrupter shall be installed in
a readily accessible location"

"(A)(5) Unfinished basements - for purposes of this section,
unfinished basements are defined as portions or areas
of the basement not intended as habitable rooms and
limited to storage areas, work areas, and the like"

That is seen to be pretty unambitious. All of the old exceptions are
gone except for a fire alarm system (that is not a smoke detector)

Or install the outlet inside the case of the furnace. The
furnace isn't GFCI protected either.


Maybe but you might get cited for a 110.3(B)
modifying a listed product.

Why not just fix the friggin pump? If water is getting into the
windings or the wiring compartment the mo fo is broke.


And 90+ percent of them out there ARE "broke". Same with sump pumps.
If I had a house that required a sump pump to keep the basement dry
there is no way in hell I'd have it on a GFCI. One day it WILL trip,
and the water level will rise, causing water damage .

My preference is a house sitting high enough on a well enough drained
area that no sump pump is required - which is what I own now.
I just did some investigating - and in ontario a sump pump does NOT
require a GFCI under certain conditions. The same applies to water
pressure pumps. I can see it also applied to condensate pumps -

as quoted below

Question
Does the Ontario Code require ground fault circuit interrupter (GFCI)
protection for sump pumps or water pressure system pumps in homes?
Answer
No, the Code does not require GFCI protection of these specific
appliances unless they are supplied by receptacles that happen to be
within 1.5 m (5') of a sink, are installed out of doors and located
within 2.5 m (8' 2") of ground level, or are within 3 m (10') of a
pool or hot tub, or as required by manufacturer installation
instructions.

Rules 26-700, 26-710, 26-714, 68-068.

I have been told a single twist lock ceiling mounted outlet for a sump
pump is allowed without a GFCI
