Default What sort of outlet pressure can a sump-pump generate?

IDK what well pumps you're looking at or where you get your prices,
but a basic well pump can be had for $125 too. What well pump costs $1500?
Even typical submersible costs less than half that. For something like
this, can probably find low cost or used ones on Ebay too.


Probably the cost of the snubber to fit a barrel...

Seems like overkill to me for the purpose, though, too...guess depends
on just how big the rain barrel really is--just a 55-gal drum wouldn't
go all that far or last long.

A 4" 1/2hp on Amazon for $110+free shipping is still 25 gpm nominal
barring the outflow restriction to a 5/8" garden hose or the like...of
course it's max 125-ft/85-ft rated head and with no lifting loss would
be near 50 psi exit pressure one would guess (presuming numbers aren't
grossly overstated).

For half that, could go with a general submersible plastic utility pump
(Superior Pump 91250) that's 25-ft head/30 gpm that's probably a lot
more suitable to purpose.
