Can I use two 30A breakers together for a 60A water pump?
No, and the level of "not understand what you are doing" is concerning.
60A at 240V (220 is at least 50 years out of date) is also 60A at 120V, twice. Two 30A 120V breakers are exactly ...

How can I fill a wheelbarrow tire when the bead is gapped away from the rim?
Looks like the typical gap one gets when mounting a tubeless tire. You'll need to get the bead to seat against the rim as you pump air (hopefully quickly) into the tire - a hand pump might not do it. ...

In what situations could "dirty water leak into" municipal water pipes besides a catastrophic loss of pressure?
When there is no flow in an underground water supply pipe under pressure, a small crack or a loose joint in the pipe can only leak water. Contaminants can't get in.
However, as soon as there is flow, ...

How can I fill a wheelbarrow tire when the bead is gapped away from the rim?
Take it to the local tire store, and ask them to inflate it - they'll use their bead-blaster machine to mount it. Should be little to no cost.
The next time it happens, ask the tire store to put an ...
