The bathroom tub had a slow drain and really odd gurgling. The master bathroom sink draining started fast then really slowed down. Also, a bubble would come back up occasionally. When I got into the crawl space I saw all these connections going in from the side. I know this is wrong because it’s causing the slow draining and gurgling but I couldn’t explain why.
These connections do not look right.
I’m thinking they should coming in from an angle, not at a flat plain.
Is there a NACHI resource, youtube video or resource you recommend to learn how many connections should be connected?
Any thoughts you have are welcome as well.
I referred it to a plumber for further eval and repair/replacement.
Was it just in the bath tub and bath sink. I have a drain in the bath tub that starts to gurgle and slow down just before the drain stops completely and then I have to snake it.(hair) After I snake it ,it runs great until it happens again. My venting is OK
