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 highquestion 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 thanks
