I didn't realize that. Thank you for the correction.

And your vents on the toilets are wrong. They need to be downstream of the toilets rather than where you show them to protect the toilet traps from being siphoned. Tim

I’m not a professional, but a few thoughts and observations… 1) Venting all the trap arms like you show is good 2) For the lav and tub, although maybe not required by code, I’d consider 2” drain lines 3) Off the rolled wye on the toilet vent (if rolled 45 degrees), I think the 45 you show...

Got the drains and vents finished and passed inspection so I can get this covered up and the slab poured! I have learned a great deal from this site and appreciate all of the expert information that has been generously contributed.

After a little more research, I found I can't share the vent between the toilet and catch basin the way I had it. This is the layout I'm planning to use tomorrow. Please let me know if you see any problems. thank you for all the help!

OK, I think I have something that should work well. Before I cut, glue, and call for an inspetion can somome please let me know if this basic layout and fittings look good? The line from the sink will have its own 2" vent raising about 8' then connecting to the roof vent line. All waste...

Here is a drawing trying to show what I'm considering for the drain and vet connetions. Does this look OK and any suggestions to improve it? What would be a good way to vent the catch basin? thanks

I'll provide a drawing showing what I'm planning... Thank you for all the help and advice!

More specifcally, I need to connect the toilet and catch basin (both 3") into the 4" outside line to the septic. Can I connect the toilet and catch basin together via a wye, and have a 3" vent stack up the wall where the line exits the building? I believe this would be a short horizontal...

To issue the permit here, they only required me to specify how many of each type of fixture will be installed. I had to submit a drawing for the septic tank installation, but not the internal plumbing. They are two different departments here (soils and plumbing). What you describe, sure...

Hi, I’m looking for help on a proper way to rough-in drains for a bathroom in a shop. There is an existing 4†drain on an exterior wall. I need to connect a toilet, utility sink, and catch basin for a floor drain. The building is serviced by a dedicated septic, so I understand I...

Thanks! I checked again with the inspector and misunderstood the trap requirement. I don't need the external trap, only a vent for the internal trap. I do need to use a primer in the catch basin so will look for something that will work best for that. Any recommendations on the best...

Sorry about all the questions and I appreciate the help. I'm just trying to verify the trap plumbing appears to be to code (UPC here) before I order the catch basin. Please let me know if this looks wrong or if I can give more information. thank you...

OK, thank you very much. I think I explained poorly. The trap would be external to the catch basin. The inspector said I need a trap and a primer for this use. Does a trap like this look acceptable, with the left vertical being a vent? Thanks for the advice on the clean-out...

Any advice or suggestions would be greatly appreciated. thank you!

Here is a little more information showing what I need to plumb the drains for. It is a small bathroom on the side of a pole barn. The catch basin, toilet, and sink will all go into the 4” drain pipe leaving the building. thanks, Tim

Hi, Can I use a running trap without a cleanout on a catch basin like the one shown here? Or is a cleanout always required for that? Thank you, Tim

I don't expect to lose oil and cost is an issue, so I'd like to avoid the seperator. Is there a standard technical definition difference between a drain and a sloped surface? For example, is a shallow trough sloping toward a door or outside wall considered a drain? thanks, Tim Tim

Would this be an accepted option? A grated trough and a sloped under-slab pipe (3"?) dumping into the top of a recessed oil seperator...? thanks, Tim
