This is not rocket science. All you need to do is dig a ditch (good
exercise BTW) lay in a new larger pipe and connect it. Also may need a
building permit in some areas.

I would do it myself including digging the ditch with a shovel. I have done
this before, spent several weeks digging the ditch, but felt great after
all that exercise!

I would replace it with galvanized pipe 1" or larger (easier for
do-it-yourself), plus get a larger water meter from the water company to
equal the size of the new pipe.

(May be 1" pipe from the water main to the water meter, but a 3/4" water
meter? Ask water company what you have and ask for advice about what you
plan to do. If you have a 3/4 water main pipe going to the street, it would
be silly to install a 1" pipe from there to your house unless you also
replace the pipe to the water main and the water meter with 1".)

When the guy from San Jose Water Company came out to see why water-flow
was
inadequate for our new sprinker system he blamed the galvanized steel
main
water line, and said he expected a plumber to charge us about $1200 to
replace it (it's about 70 feet from the meter to the house).
So far we've had one plumber come out to give us an estimate, and he
first
said $2800, then $2500, and finally $2000.
I'll ask other companies for estimates, of course, but was wondering if
anyone in here has had this work done recently, and how much it ended up
costing.
