  • Insulation on the dishwasher is mostly for noise and stopping moisture or heat from damaging surrounding cabinets.

    The dishwasher is using new water or heating water. It is not designed to keep the same water hot for an hour plus.

    The whole back of the dishwasher is a tiny piece of plastic. Not insulated at all. Some fancy ones now put a little insulation on back.

    But the idea isn’t to keep heat trapped to wash dishes, but to keep heat from being released and damaging things.






  • You can’t check for back feeding.

    Cable coming from house to pole has no power. Electrician goes to hook up wire. Homeowner puts on generator. Electrician gets electrocuted.

    Yes the testing and hooking up could be a small window of time but a fraction of a second after testing is all it takes.



  • Space isn’t really a vacuum

    Wait what?

    Space is a vacuum.

    Could argue it’s not a perfect vacuum. We haven’t created a perfect vacuum on Earth but we have come close.

    If I have a container and remove all the air inside. I have created a vacuum. Not a perfect one, but a simple vacuum.

    If I add rocks to the container. The rocks are now in a vacuum.

    Just like space. Space is a vacuum and there is “rocks” in it.




  • You have to understand what profit is.

    If I make a church, collect 1 million from my congregation. Then, I pay myself 1 million for the job of being the pastor.

    My business, the church, is non-profit. It had 1 million in revenue and 1 million in expenses. No profit.

    Now, I would be dumb to pay myself the million as a salary because then that million gets income taxed. I’d “buy” 1 million dollars worth of bibles for Uzbekistan and never fulfill the order or something. Launder it.

    The idea of why the church doesn’t get taxed is sound. People pay income tax, church collects taxed income, church spends taxed income to better community.

    They are essentially supposed to be a middle man. If i took my taxed income and donated it directly to buy bibles for Uzbekistan. Then it doesn’t make sense for my money to be taxed again. So if i give my money to the church and they give it to Uzbekistan, then why tax it?

    Problem is our tax code has loop holes

    A church was never supposed to buy a private jet. Yet it has become a business expense.



  • Ohh I see now.

    Yeah 160° is too hot. But people do it. Small tank multiple showers needed. You can stretch it.

    I was saying for people that have their water too hot. The regulator inside the US mixing valve has a stopper so you can’t go to max hot. That’s all the piece inside does, stops you from turning the valve more. Doesn’t help reglate the temperature. Someone in comments said their regulator is bad and I thought it was OP.



  • If you live in the US, then you probably have a standard mixing valve

    If you live elsewhere, it’s probably a thermostatic one

    For US:

    You want to turn your handle all the way hot to clear your hot water lines fast, it’s room temperature in the hot water lines. Once the water is hot, then you start mixing in cold water.

    The first cold water is from the lines in your house. It is heated or cooled by your home, basically room temperature water.

    So say I turn the valve on full hot. Pure hot water is pouring out. Now you add some of that “room temperature cold water” to get to your perfect temperature.

    Now, once you run out of “room temperature cold water,” it will start pulling water from the street.

    I’m guessing you live in a cooler climate area?

    120°F + 70°F = perfect temperature

    But if the outside water becomes, say 50°F after you use all your water stored in your cold water lines

    120°F + 50°F = colder water

    So you have to add less 50°F water, which means slowly creeping your valve up until you have steady temperature water going to the valve.

    Things like the type of water heater matters. If you use a tank then as you use water it adds water. If you keep your tank at 120° and you’re adding 70° cold water or 50° water to the tank matters. You also have “room temperature water” in your cold lines going to your tank at first, then colder water. So that creates another “lag” in temperature

    US standard mixing valves aren’t as nice as a thermostatic valve. They are just cheap and standard and work well enough in most places.

    Thermostatic valves allow you to select, say 100°F water, and the knob just controls the water flow rate. No matter what, the water that comes out of your shower will be 100°F. As the water coming into your house gets colder it will automatically adjust. As the water from your tank gets colder, it will automatically adjust.

    Sounds like your valve is working as intended though
