I am going to be plumbing my 1500 sq ft basement this weekend. i have already done all the waste lines (when I poured the concrete). I also installed a little giant sewage ejection pump/basin. link is here. (the top one).
The basin is in the bathroom, which is closest to the main sewer line for the house. Where I live the building code is based on UPC 2006. in the bathroom there is a total of 10 dfu units, not including the ejection pump (total of 12 units go into the basin). I am able to vent 5 of the bathroom dfu units easily, up an existing 2" vent I put through when I did a remodel upstairs some time ago.
The pump is able to do 80gpm, which, from what I can gather allows me to vent it in 2" up to 150' developed length.
My questions are:
1. do I have to vent the sump seperately?
2. how does one calcuate the dfu of the ejection system itself?
3. are there any other constraints on ejection system venting, like no more than XX feet horizontal, etc.
Ideally, I'd like to vent all 10 dfu of the bathroom up that one vent, so I don't have to run another one!
We don't always get what we want, though!
Thanks,
Ian
