I've been trying to figure out a simple way to connect all of the sanitary piping I have on a project.  Particularly when I have a 3 pipe connection.  Anyone have any savvy tips that might make this easier.  It's very difficult when the piping slopes and the routing solutions aren't the greatest.

Properly built fittings will likely fix your problem. I've found that there are some good manufacturer created fittings, and some very bad ones that require a lot of adjustment to make them work properly. A lot of the OOTB fittings work great but aren't dimensionally accurate to what is manufactured, that's why we went to either in-house or manufacturer created fittings. I'm not entirely sure if this is what you're looking for but it sounds like it.

We also try and steer clear of sloping pipes, even though Revit has come a long way with this. We'll do it if there are concerns about collisions, but most times we can avoid it. I've also found that connecting to a horizontal pipe and then sloping it tends to work better for routing solutions.

HTH and isn't too late.

Has anyone had troublke with the 45 degree connection in sanitary pipe. I will try to connect the pipes together and the connection automatically turns the opposite way.  Is there an order you have to connect sanitary piping?

kmeasamer,

I'm guessing that the attached image is what you're referring to with Sanitary Tee connections.

I've found that if you get the acute sanitary connection, simply erase the fitting and select the downstream pipe, drag it's connector to the upstream pipe and use "Trim/Extend Single" (TS) command to attach your branch and it should connect with the proper  angle. Try this with the upstream pipe segment and you'll get the acute angle again. It's a bit of a pain, but at least it'll look right.

I'm not sure if this has anything to do with Element IDs and the Primary connector, but it might. I've found the Primary connector likes to attach to the lowest Element ID when it can. I discovered this behavior when I was building a P-trap fitting and the trap would insert sideways, like a b. I found it made a difference which pipe was drawn first, the horizontal or the vertical.  If the vertical was first it would work because the Primary connector was on the top of the trap. I re-assigned the Primary connector to be the outlet or horizontal since I generally draw that pipe first in my workflow and everything worked out great.

HTH,
