I need to bring a condensate line out of a basement below grade. What's a tidy way to seal the wall penetration and cap off the conduit in a water tight fashion?
I recommend using electrical PVC conduit and fittings instead of plumbing PVC. Electrical PVC uses extra long sweep elbows designed to make pulling things through it easier. I can maybe see some merit to the above idea of being able to get the pipe a touch closer to the house, but it seems more complicated than needed and I still think the electrical PVC with the long sweep elbows would be easier. Also, plumbing PVC is not UV protected and doesn't hold up to outdoor conditions as well.You can put together a conglomeration like below and it will allow you to thread your lineset through the 90 and cement it all together, then run it through the hole on the basement wall. The 4" 90° will allow the refer lines to come in while having a sweat ell or close bend on them. This way it would be able to bring it up close to the house. Just a suggestion based on what I did once in a similar situation. It also will make it easier to get a seal at the wall.
Use whatever size PVC minimum that will work through the wall with the lineset mass you have.
