I have an 8 year old house with unfinished basement. The person I purchased from was the builder and stated he had roughed in drains for vanity, toilet, and shower in the basement slab. I have eventually broke through and found all three drains. Originally hidden under the concrete pour. My question is regarding venting. The drains (1 1/2" Vanity, 4" toilet, 2" shower) I assume tie in together and go straight to the ejector pump which is some 15-20 feet away. The ejector well appears to be vented. Will that be sufficient for the new bath room? Or should I have additional venting for the fixtures to work properly? I imagine I can easily add a vent when bringing up the vanity drain with a T (to tie in to the ejector well venting), when putting in the vanity, but as for the toilet, and shower, I don't see an easy way to vent those. btw... I can see the shower has a trap since there is standing water visible. Toilet has it's own trap, and vanity drain will have it's own p-trap under sink when installed. Hoping this would be a pretty simple build. Thanks for any help guys!
p.s. Would also like to have a laundry area right next to the bath. Can I link the drain for washer & laundry sink to the vanity, as it will be right next to it? Also would like to add another wet sink not too far from the ejector, thinking I can tie in directly to the ejector. Would these also need vents? If so they should not be too difficult if I can just tie in to the vent coming off the ejector pump. Hope this makes sense!
