There are two, one on each side of the toilet, closet bolts which hold the toilet to the floor. If there are caps over the bolts, remove or pop them open.

There may be more pipes in your home than you think. Your home gets all the water it needs, either from a municipal water connection or from a well, through one central pipe, which branches out and distributes water to all the other places in your home that need it.

If they lack a good first impression then this may indicate that it is going to have an impression on their work. In most cases, you would have taken the time off work for the plumber, and what can be worse than waiting all day waiting for them to arrive?
And the way to know what's sufficient? Well, until the work is done an the bill paid you won't know for certain, but this is the best that can be suggested and normally works very well.
