Problem 1.

Faucet water runs red/brown (think red clay) about 10 minutes after
tree service drives their (big) crane truck across corner of yard to
the driveway.

Q1: Coincidence or likely caused by the crane ?

Q2: Tree guys want me to believe that vibrations from the truck into
the ground shook some rust loose in the water pipes, possible ?

Q3: If a tree removal service runs crane over the yard (shortcut to
the driveway ) then runs over the water meter and or the ground above
the line feeding house from water meter are they responsible for a
break ?

Problem 2:

So now i want to find some proof evidence the water line is
broken/cracked or not.

Q4: how does one proove the line has a break/crack without physical
evidence like water coming up out of the ground ?

Q5: Are there any guidelines or standards for water pressure at the
faucet ?

Q6: Who publishes the actual water pressure you should expect from the
city water service ?


Thanks for any helpful replies.
