ok,, check this out..
single dwelling house,, no main sewers available close to lot.
all the waste drains into a 2'x2' cement pit, no vent. outside.
1 hp pump,,(dont know brand) discharges on a 2" line..
sounds fine right?
burried underground about 3 ft.
outside the pit, 2"check valve, line turns and heads uphill gradual rate,
maybe max 15' (thats 15 ft max height)
but..the line runs approx. 230-240 ft. to dump into nearest manhole,,,
end of sewer line,, but its up hill.
so to be clear,, 240 ft. uphill 2" line,max 15-18ft high
question is,, i cant find out a sizing chart, for this application.
is this the right pump size?
the only thing i can find is ....
2" pipe minimum capacity = 21 gpm
i dont know much about the pump,,cant read it..
its less than 2 yrs old,,the whole system, and is not pushing the waste with
the water..too much head, my guess.
how can i size this correctly?
i love being a pain in the ass
