My new apt has a very neat color scheme, but unfortunately has been painted many many times and now in several rooms, paint is peeling off the walls to reveal the old color(s). How do I fix this? Do I have to scrape it off and sand or just prime? Hoping to do a better job than the last tenants. Thanks! Oh . . .and yes landlord gave permission to paint whatever I want.
no, they don't, the pressure is very big
Depends on the shape. The traditional cylindrical shape would not float and could definitely not be used as a floatation device.
Brass fittings would be my choice as well, but when you get near an exterior wall where the pipes might freeze, you need to use pipe insulation for all of those pipes, and/or use pipe heating cable this cable usually has a thermostat that will turn on the heat when the pipe reaches a certain temperature and prevent the pipes from freezing.
The buoyancy of any object is equal to the weight of the water the object displaces. If the object weights less then 62.4 pounds per cubic (fresh water) the object will float. If not it in turn will sink. If the contents were discharged the tank most likely would only be slightly buoyant and not make a good life preserver. So to paraphrase the Myth busters it could be pausable, but I would prefer a Coast Guard Approved Vest.
