 Slip fitting in vent line
Author: walldocmp (ME)

Would it be acceptable to use a slip x slip 90 deg elbow in a vent line.

Or does the whole vent system need fittings with hub connections? I need just a little extra space to make a turn and the slip fitting will work and the hub wont. Thanks.

What is the difference between that elbow and one with "hubs", since they are essentially the same fitting.

If you run a string from lip to lip thru the fitting you'll see the vent 90 is shorter travel.

I was referring to his original posting about this elbow versus a "hub" elbow. NOT a vent 90.

oops, ok, I didn't read it that way since your post came in sequence right after packy's I thought you were referring to the fitting he mentioned.

Thanks once again Packy! As far as HJ's question I was just not sure if they could be used interchangeably as the description on the hub type said they are for non pressurized systems and the slip kind said for pressurized systems.

The pressurized fitting is an "overkill" when used for DWV purposes, besides not having the smooth flow interior that a "liquid drain" fitting would require.
