A fairly big local plumbing company is in the middle of replacing my
sewer laterals. It's almost done - the pits of the trenchless
replacement are open waiting for the city inspector before they finish
up the work (hopefully, making the cleanouts accessible and filling,
compacting and some concrete replacement).
In the process of doing the work my water main busted. They tell it was
already leaking. When I told them my water usage was minimal (less than
$10/two_months), the work crew said the leak had been smaller, but
they'd exacerbated it. At that point (a week ago) it was (by my
estimation) 1/2 to 1 cups/minute, but over the next couple of days
increased 10 fold and I've got the water shut off now, and have my house
water supplied by virtue of some agreeable neighbors who let me hook up
my house water to theirs with a couple of garden hoses.
The company has given me what seems like an OK bid ($2300) to replace
the old 1/2" galvanized and obviously badly rusted water main pipe with
copper. The owner of the company refuses to take responsibility for the
busted line, and I am sure not going to contest his position on that.
I've never taken anyone to court and I'm happy with the work they've
done and they did bid my sewer work low, doing a free camera inspection
in the process. Besides that, they cleared out a clogged tub drain for
The owner came over and gave me an estimate and said he'd use 3/4" L
(around 30 feet all in all) underground and go to the house and then use
3/4" M (around another 30 feet) to connect to the house plumbing, which
is old 1/2" galvanized.
The pressure of the water coming from my neighbor's house is 90 psi, as
measured by another plumber (a sole proprietor) who came over here to
bid the job. I'd use that guy, but it looks like he'd use an uninsured
worker and since I don't have a general homeowner's policy, it looks
like I better pass on him. He said I MIGHT be required to put in a
pressure regulator if the work is inspected.
1. Should I be happy with 3/4" for the supply up to the house plumbing?
The utility tells me that it's 5/8" that supplies the meter to my house.
I ask because the response at alt.home.repair was that I should insist
on 1". The house is 1925 square feet, there are two bathrooms and an
average sized yard. I have a washing machine and no dishwasher
presently, but may install one.
2. Should I ask for L size under the house? Code says M or larger.
The SP plumber says that people often complain (especially initially)
when running new copper water mains under the house about the noise of
the water running in the copper pipe. Would thicker pipe lessen that
effect? He also said that plastic hangers are quieter than copper
Thanks for any clarifications.
