No, most people don't have the need for a "dish sanitizer" in their house. Either they do the whole job by hand, or they scrape off the big stuff with a fork or knife and let the machine do the job it was designed to. Why the need for such a quick cycle? If noise is the issue there are plenty of very quiet dishwashers on the market. All of that being said, the dishwasher you want has already been mentioned in this thread. Miele has a few models with 10-20 minute cycles that can fit into the same undercounter spot other residential dishwashers can. You're going to have to pay up, though; the dishwashers themselves cost thousands of dollars and that's not including the cost to have a 240V circuit installed.

I always wonder why people hire contractors for big jobs without really knowing how they will work. Speaking as a contractor there are certain clues that will tell you if they are good or not. Do they communicate well? Do they call you back in a timely manner? Do they show up on time and, if they don't, do they let you know ahead of time? Do they keep the job site clean? Very important. How do they handle changes in scope and unforeseen job site conditions? The good ones will warn you ahead of time about the conditions they can not predict and have some sort of agreement in place about what to do if conditions turn out badly. In Philadelphia I often run into botched previous renovations that structurally compromise the home. I tell people what the job will cost if everything inside the walls looks good. Then I tell them what might be inside the walls (termite damage, bad wiring, structural deficiencies, etc.) and we agree on what to do if I find something bad. I want to find the problems early so that neither the customer nor I are locked into an unrealistic job scope. Basically I build in an out for the customer if there is a problem. The contractor you hired should have done a test first. Also it is good to hire someone for a small part of the job first before hiring them for the big part.

Thank you for your response, but kids’ want their way and their feelings aren’t taken into consideration all the time, by bio-parents just as easily as step-parents. A child thinks like a child, which generally means self-serving interests. Kid wants yet another bowl of ice-cream before bed; if the step-parent just says No, that is not SM being manipulative or wanting her way. That is SM acting like what she is, an adult and an adult in her own home. Call it what you want, “children first,” etc. There are many names to put on a BM trying to put some sort of spin of child endangerment in dad’s household, that he now shares with his wife. Now, I can’t say for sure what is really going on in that home, but I’m suspecting neither can you. The older, more knowing kids, don’t seem to have THAT much of an issue. Other than the pot, the examples you listed above just don’t scream out abuse. They more-so scream out: big misunderstanding. And, if you allowed your ex- to smoke pot when he was with you and your children, you might want to ask yourself why suddenly now that he is doing it with someone else, somewhere else you are so-o concerned about it and diminishing him to worthless father status. I’ll tell you what the future is for you and your children, because I’ve seen it and heard of it many a time. I’m not saying there is parental alienation syndrome going on here (PAS), because, again, I don’t know all of the facts. But, to me it sounds like you think you should have control of not only your children, but your ex- and his wife, while your children are in their home, at least. And/or, maybe you divorced your loser husband expecting him to suffer for years and years, and instead he found a new wife/ woman a little too quickly? Any way, it is extremely easy for a BM to take minor incidents that occur with her children and blow them out of proportion. This begins a cyclical effect where the kids and BM feed on each other, encouraging each other to think that dad, and especially SM, are Evil or losers or even abusive, and that they don’t have to be listened to, which in turn, upsets dad and SM, so they feel they have to somehow try to get the kids in line further, which then gives the kids even more fodder for mom, and the cycle continues and grows. But, as a BM, I admit, you pretty much have all of the power. It is very easy for you to use that power however you see fit. The court system, society as a whole, will all give you the shadow of a doubt and the shadow of a doubt alone because you are a single mother. Keep things going, and your kids will wind up hating their father, hating SM, and loving and relying on only you. You may go on to get involved or remarry, and the kids will go on to think of step-dad as their “real” dad because mom is promoting him so and not at all just because he deserves that role. There will be issues and drama beyond belief for years to come due to Evil SM and deadbeat bio-dad (that will be your and your children’s spin, anyway). In the end, your kids will think the world of you and hate/ blame their father. When, in reality, the only thing dad and SM may have done wrong is to dare to marry and to try to be happy with each other and dad’s children in their own home. Yes, to some BMs (and SKs and others) that is a crime. Stay out of it. You are the kids’ mom and he is the kids’ dad. You both have the right to parent; just because YOU feel he isn’t parenting that doesn’t mean he isn’t parenting. Regardless, it is up to you how the rest of this plays out. Enjoy your power.

If it was a dip tube issue on the old unit, the new water heater would have a new, intact dip tube and should have taken care of that. Is the water heater plumbed backwards? That could cause what you are experiencing. Looking at the front of the heater, the right connection is usually the cold water inlet side and the left is the hot water outlet side, it may also be labelled/stamped into the WH shell. Feel the piping with your hands as hot water is removed from the tank. Try a test: Have someone at the water heater to feel the hot water discharge pipe as water is run at the bath. Does the discharge pipe turn cool in coincidence with the tub water turning cooler? It should only go cooler after 30+ gallons have been used. If it cools sooner, get the plumber back to check things out. Is there a tempering valve near the water heater? Tempering valve sense the hot water temperature and mix in cold water to maintain a constant discharge temp to prevent scalding. Or, some set the water heater at a very high temp and use a tempering valve to give them extra gallonage of hot water. If you had one that was faulty, or set to too cold a temperature, you could experience what you describe. They might look like this: https://www.supplyhouse.com/Mixing-Valves-322000.  Also, the tempering valve does not have to be near the water heater, it could be installed closer to or very near the tub/bathroom.
