Reach4 - haha - my "plastic" 4" pipe is pooched if a truck runs over thin or thick PVC or even foam core ABS. Installed no issues as the run to the septic is nowhere near any vehicle traffic. At -20C a good kick to thin walled PVC with a steel toe might get it to crack as well but I hope not...

Be careful of too much slope. Anything 4" and bigger is typically 1:100 (1/8 per foot). Too heavy a slope and the liquid out runs the solids leaving the solids to build up in the pipe. As mention by Mr Tee you need wye's at the septic connection. I'd run an LT 90 into the straight portion of...

Hey Folks, I was just watching a Youtube video from a respected plumber and he mentioned in passing that you are only allowed one ABS to PVC connection in a residential plumbing system. When I read the OBC it does not specifically say this based on my interpretation. Not sure why only one...

No, unfortunately I don't think so. The top of my 4" main drain is is located about 2" below the floor joists (floor is sealed and insulated) and runs against ( parallel) to the main beam. The configuration of a wye would require a much bigger hole configuration up through the plywood and...

Seems like it'll work but again I'm not 100% it will meet code and unfortunately off grid doesn't mean code won't apply. Code applies to plumbing just doesn't strictly apply to electrical because it will not be a grid tie home.

Fantastic. I have something similar to one of your sketches. I modified it to should a better rendering of what I have. The only thing I haven't shown well is the 4" main pipe is about 8" below the plane of the toilet drain arm so basically connects with a santee do you think the fact the vent...

I think what you said is absolutely right if you're having to fight a pressure, water will back up, fill the pipe and create a syphon as the"slug" drains. The vacuum you mention is the definition of a plumbing syphon - you're sucking the water out of the toilet. I think my 65" line is OK but I...

Appreciate the info. Yes I understand a wye would be best for a directional push but in this instant makes my plumbing holes through the floor much more complicated and harder to seal and insulate. A santee allows a simple round hole up through the floor. The "drop" from the bottom of the 3"...

From Ontario Canada I'm building an off the grid home completely alone. I need some advice on a toilet drain length. I don't think I need to vent the 60"toilet trap arm but man is it hard to confirm. I can't see how a syphon can be generated but maybe there is a scenario I'm not considering...
