We have a high-efficiency furnace. Two pipes are coming outside the house as expected. However, right now, there is at least 2 feet or more of extra PVC on the exterior showing.
Is there any harm in removing this extra length for cosmetic reasons? Also, what is best to use on the endcap to prevent debris, etc. from entering? I have seen these triangular looking endcaps, but not sure of the name.
There is an overhang above the pipe. I'm guessing 1.5 - 2 feet.
