Remember that many popular cake mix brands contain trans-fats (partially hydrogenated oils). The FDA has determined trans-fats to be unhealthful and has banned their use in food products. There's a 3 year phase out. The below linked article notes that it's expected the ban will reduce deaths from heart disease by thousands of people each year. That's significant. Maybe not in regular grocery stores, but there are mixes available with less dangerous ingredients. Trans-fat ban article

Advising others is iffy, in an internet forum. Perhaps the precise term needed goes missing, or a key concept is missed. There comes a point when it is better not to play plumber. I know enough to be aware of the limits of my knowledge for my own use. In a public forum I'll advance cautiously. Here we go. johnliu you are in California. For future reference 2007 California UPC is here http://bulk.resource.org/bsc.ca.gov/title24_part05.pdf It was manhatten42 who led me to it. There is nothing in there about a Group as large as the one you just described. Either your AHJ will consider it all still part of the Group, or not... My bet is yes, it's going to be do-able as a Group, for the reasons described in the other thread linked to in the OP about Groups. It can be done with one P trap. It can be done with two P traps. If you have two P traps or want two P traps, the connection point fitting to use is very very particular. It's described in these recent threads. http://www.terrylove.com/forums/showthread.php?36810-double-sanitary-tee http://www.terrylove.com/forums/showthread.php?36767-Single-to-Double-Sink-Vanity-%28again%29 e.g. Double fixture cross, "back to back fixture fitting", e.g. (R&G Sloane #91491 in ABS) In the second thread it is explained why not to add a wye horizontally and then connect each sink (with its own P-trap) to the two ends of the wye fitting. If connected that way, then if a draining sink got stoppered, the water draining already in the DWV pipes would siphon the other sink's P trap out, break the seal and allow sewer gases into the house. I hope that explanation meets the post-posting pick-apart scrutiny test. If your Wye you wrote about was intended to go vertically, it's also a no-go. A Wye would make the trap arm do downhill at 45 degrees, and that is a 3/4 S-trap (a no go). The reason is that you want to ensure your trap arm always remains in the horizontal plane (with a minor slope) until it reaches the vented DWV pipe. Remaining horizontal allows the trap arm to self-vent. So, no to the Wye connection. An exception is with Venting between the Trap and the Wye, but nobody ever vents first and then "Wye-combines" as it's not efficient use of wall cavity space. In some situations it is a solution to add an AAV to vent the DWV of a kitchen P trap. Learn more and hire a plumber if you need two P traps connected in new plumbing. And take no action based on learning anything from any smart person on the internet. Plumbing requires thousands of hours of training and shaping the geometry of new drains is one of the hardest subjects. hth

I don't get why people get so worked up over it. Sheesh. Aren't there a lot better things to stress you out? Disclaimer: I have mostly atomic clocks so very little resetting around here. I don't have a structured life, having to report somewhere at a certain time. I sleep when I want and do things when I want. The only, albeit slight impact on me is store hours but an hour give or take is petty in my life. And I'll say that when I was working semi-normal to normal hours I really enjoyed having the sun in the afternoon. When I'd work nights, it was nice to have the sun up "earlier". Seems to me the ones who go craziest over it are the ones impacted the least! My dad used to get so worked up over DST. He'd be screaming "YOU CAN CHANGE THE CLOCK BUT YOU CAN'T CHANGE THE SUN!" Uh yeah, don't you get it? You CAN'T change the sun, so you change the clock. In today's popular vernacular, "DUH!" And ironically, he seemed to always enjoy having daylight when he'd be driving home from work. My estimate is 90% of people who grouse about DST are hobbyists. They make a hobby out of complaining! Nothing FORCES you to change your clocks. Go by your own time. I'm on CST (Cynic Saving Time) year round. I don't get worked up over it. Saves me stress and provides entertainment watching people making mountains from the proverbial molehills.

There is a very good chart on the InstantPot website. It would seem that your frozen roast would be about 20 minutes under pressure with a natural release. You do not add extra time if the meat is frozen, the IP simply takes longer for the temperature to rise initially. https://instantpot.com/instantpot-cooking-time/
