Re: 3\" or 4\" PVC for septic
SDR 35 isn't for storm drains. It's the good stuff for sewer drains and sewar mains. It's gasketed so there is some movement when it's in the groudn as oposed to glue pipe that will break if your ground has any movement.
Use Sch 40 under the slab and if your close to your septic, stay with it.
If you need to travel any distance at all, you will be better off using SDR 35.
To get back on topic about 3 inch versus 4 inch. I've never had any problems finding 3 inch fittings. That's either an old time issue or a wives tale. I've heard it allot myself, but for the life of me, everyone has lots of 3 inch fittings. It's very, very common in new homes.
Don't just compare the price of the pipe, but compare the fittings too. I think the difference is enough to make 3 inch more desireable.
