No it will be just fine 2" of water wont cause any problem except to remind you to try harder with the leveling next time you do it.
Almost all that I've seen in regular house construction are 8 inches thick.
If you live in an area where you have frost it should be below the record frost depth, usually in the North it is a minimum of four feet. If you are running copper in the ground out west you can go substantially higher in the ground due to the lack of frost. I would recommend that you look at the building codes for your particular area as the requirements for each state and region can differ. Bed the pipe with sand below and above, 4-6 inches is a usually required above and below depending on ground conditions and relevant region of the country. You also want to make sure you are using the right grade of copper pipe made for direct burial.
3" below grade. To make this more understandable, sketch it on paper. Being at grade is level with the soil, with no sloping. So put a G and a line for "at grade" and draw inches above the top of the foundation to see how it looks: 16 inches down to 11 inches == TOP edge of the Wall. ( Has nice casement windows, providing natural light. Plenty of accommodation given for bushes and plants without interference to windows.) 10 inches down to 6 inches 5 inches down to 0 inches or Ground G ======= AT Grade (Ground), level with the soil== \\Soil grading downward away from structure.\\ 1 inch below 2 inches below 3 inches below ............. The top of your wall would be lower than the outside ground. The foundation could have no windows; they'd be useless even if placed way up at the top. Therefore it would get no natural light. Soil would continually erode at the top edge, meaning, over the years the foundation would appear from the outside even lower than what it is with being below grade. Worse-- no one will be happy with appearance or function.
Here is what the IRC (International Residential Code) says about footings and proper placement. R403.1.4 Minimum depth. All exterior footings shall be placed at least 12 inches (305 mm) below the undisturbed ground surface. The basic reasoning for getting down to natural ground level is to get to get below the level of undisturbed ground surface. This includes the ground surface likely to include roots and other bio materials. Undisturbed ground is more likely to properly support the weights applied from a structure over the long term. Take for instance tree roots
Larger in Gas Welding. In all arc processes the HAZ is concentrated in a couple inches around your bead. In gas welding it can be double or triple that size.
You have to use a spirit level, a big one. But two inches isn't too bad.
You can get them in many home improvement and department stores and they adjust with a typical range of 16-22 inches from ground to seat . I'm trying to find one that will adjust higher for my tall father, he needs about 25/26 inches. Anyone know a model that goes higher than 22 inches ground to seat?
