I am about ready to take my plumbing test. On the drainage diagram they have a sewage ejector it is 25 gpm. my question is how many dfus does that equal? I have never worked on one. There is a toilet, shower and vanitie on the ejector. Please give me some help. Thanks

found this on line
"a. For a continuous or semicontinuous flow into a drainage system, such as from a pump or similar device, 1.5 fixture units shall be allowed per gpm of flow. For a fixture not listed, use the highest d.f.u. value for a similar listed fixture."...

so, i guess 25 gpm translates into 37.5 DFU's..

this is where i found this..

P/S, good luck on your test..
