Why does this drain smell often?

This bathroom sunk drain seems to have a funk every once in a while especially while washing hands, the water draining seems to “push” smell up to my nose. Is it piped wrong? Or just some bacteria lining the pipes? None of my other sinks seems to smell like this one while using the w sink.

Nut Cracked While Tightening

The nut on my new kitchen faucet supply line cracked about 3/4 of the way around. It's been watertight with the sink running for about 10 minutes now. Am I good or do I need to replace it?

Help with Sagging Faucet

Hello, I have a pot filler faucet that, when originally installed, flush and level. It has now progressed to sagging and looking like crap ( see picture). I can get that cap at the wall off, but there does not look like enough room to see or adjust anything. I'm completely useless as far as being handy and can't get a plumber to come out for this. Any advice truly aporeciated

How do I replace this?

A very simple task has become more difficult…the diverter to the shower broke. All the replacement slip on faucets say the pipe needs to stick out 2-3”, and my pipe is a half inch too short. What are my options?

Accidentally left a faucet slightly on for 10 hours

First time home owner here, bought the house last November. We are on a well with an old water softener. I accidentally let it run out of salt for a couple of weeks months back. I have since run iron out through the softener and the water has improved a lot, but seeing this makes me think the water is much worse off than I thought. I was able to remove the stain I am mostly just concerned about the quality of our water and it ruining all of our plumbing, appliances, and fixtures over time. Any advise for me here?

Water line was hooked to outside spigot. Wanting to extend this to other side of basement. 1/2” MIP I hooked to 1/2” garden hose but it leaks (I know MIP is wrong for garden hose). What piping is this called to extend or how can I connect to garden hose without leaks? Thanks!

No experience. Can I replace kitchen sink drainpipe on my own?

I’m no plumber but I’m handy and this looks straightforward. How difficult would this be to replace on my own? Looking to get this done as inexpensively as possible so don’t want to call a plumber. Would rather spend money on quality parts and learn. If this is something I can do on my own, what things should I consider beyond what I might learn from a YouTube video? Thanks!

Crack in the toilet bowl

Opinion on if this needs to be replaced? Just noticed it after moving into a house a month ago. I saw something online saying I could drain it and put some plumbers putty on it but not sure if it’s too wide. The toilet also had a little bit of wiggle and it is the main toilet I will be using.

Is this vent correct upside down?

I hired a plumber to redo the old galvanized pipes and fix this leaking kitchen drain. The 2" vertical is the kitchen sink drain and also a wet vent for a basement sink, granted the new washer box next to the basement sink has a cheater valve vent also that can serve the basement sink. Plumber says all vents shroud be upside down. But in this case couldn't kitchen sink gunk get stuck here and eventually clog this vent?

Is this a high loop?

I've been getting some dishwasher smell and I'm wondering if the drain hose was installed incorrectly without a high loop. Is this bad? If so, should I replace the hose as well or just create a "high loop"?
