No, but I take that as a huge compliment. Our first and now second house have both been fixer uppers. Lots of nights and weekends fixing or watching YouTube’s. Plumbing is something I actually really enjoy (I think it’s all the pieces so it’s like adult legos). I hate electrical though - I have large hands and just fumble with the wires.

If it’s perfectly horizontal or even slopes a tad the wrong way, it’s not really an issue. If you don’t use it for a few days it could start to smell, but once you use it, any of the water that was sitting will flush out.

Saying that, to get a slight downward slope - cut one of the tailpieces to be slightly shorter than the other. Just a small amount is enough to give a slope. (Tailpiece goes from the metal sink drain to everything else).

If you’re in America - Home Depot has double sink kits. You can Google and YouTube for it as well.

I feel like both your suggestions are the same thing. Big thing is - working backwards - it goes exit to a p trap. It doesn’t really matter if you have a primary and the other sink joins or if both sinks join and then go to the P.

A computer processor can only give two signals - on (or 1) or off (or 0). Everything is binary on a computer when you remove all the layers.

I don’t know how it works beyond that - but it’s not just decimals, numbers - but everything. Colors, videos, programs, etc - everything is just 0 or 1. It’s the only thing a processor can do is on and off - yes/no electricity.

The key here is removing line breaks, not formatting. Nice trick.
