Why would a P-Trap be required before an air gap for a refrigerator drain?

It's preventing air movement through the drain pipe. Without it, cold air from the refrigerated space will constantly flow out the pipe, and warm air from outside will constantly leak in - wasting ...

Is my p-trap installed correctly?

Didn't know about trimming tailpices to fit, leading to odd arrangement with more pipe than needed. And more critical; that's an S trap now. The pair of vertical elbows at the wall entrance is a ...

Shower drain not level, water collects to one side of it. How can I level it without having to reinstall it?

Can chemicals soak into a steel sink and cause health issues?

Former chemist here. Stainless steel is great! Not much can eat through it, and we love it almost as much as glass. Based on that alone I'd be comfortable saying a consumer cleaner is unlikely to do ...

I recently moved into a house and it looks like a chemical has been used on the stainless steel drain and left marks. Is it possible to clean it off?

Unfortunately that looks like they used an acid that stripped the chrome finish off. No good way to get that back on.

Does the plumbers putty applied around shower drain need to dry up?

The entire point of plumbers putty is that it does not harden or dry. You can keep beating on your drain connection until you break something, or stop - your choice.

Wall drain too high for p trap

As noted in a comment, I would suggest looking for a shorter tail piece without the fancy, tall nut (which, I'm sure, works very nicely for hand-tightening). Normally the nut would be less than an ...

Most likely, this is not a vent, or more precisely, this tube will not work as a vent. F.e., this tube will not prevent that the siphon/trap will lose its water if a low pressure sets in downstream ...

Does the plumbers putty applied around shower drain need to dry up?
