Hi all, I'm new and I need help. My mom passed and I am at her house to go through things. While cleaning using the kitchen sink the water was going down slowly. When I stopped up the one side, the water went down faster in the other at times. She has had 3 plumbers out that just say " yea these Mobile homes are noted for that problem". Uh ok? One company did snake which didn't solve the problem but it did help a little. Another said it was the pitch which I'm probably not using the right word. I tried to plunge it because at one point I was running so much water it was taking forever to drain. No change. Now the pipes are leaking. I just want to get this fixed. I have no idea what I'm doing but with the right help I can get through this. I'm attaching a picture in hopes someone will be able to spot the problem and help me. Thank you
