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 ?

it was 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 ?

very likely, but possible. if so, then it should go away after running the
water for a couple of minutes

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 ?

they should have insurance and/or a bond for this. they are.

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 ?

there will be, eventually. if not, you'd have to dig some. you could turn
off all water taps in the house and look to see if your water meter is
spinning. if there's a leak, it's going someplace.

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

no.

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

the city gets to decide what their correct pressure is. ask them.


Thanks for any helpful replies.
