I recently noticed that after I hear my sump pump kick on in the crawl space, I hear a sucking air sound. It was happening a lot during the spring, but I wasn’t sure exactly what it was. Now that it’s nice outside, I see there is a spot of exposed PVC pipe. Does this mean there is a crack somewhere right around the visible pipe and that’s where the air is likely sucking in? I’ve attached pictures. The entire distance from the house to the drainage field is about 30 feet. If it is in fact cracked, would it be possible to just dig up a small part or would I need to dig up the entire length of pipe to replace? Thanks in advance.

I'm helping my brother, who recently moved to Phoenix, make some repairs to the home he purchased. The patio cover is fastened to the facia. However, the patio cover is only secured using simpson ties and nails. It's separating. I'm looking for some advice on a solution. Thank you in advance!
