Just wondering if there is any reason to use 1" pipe when replacing my
service line. I'm thinking there isn't since 3/4" pipe is running through
the slab to the main shut off valve, and I won't be replacing that.
You will get more water with a larger pipe and if you have a 1" pipe from
the main to the meter, but a 3/4" meter, you would have the option of
"upgrading" to a 1" meter. This all would come in handy if you want a lawn
sprinkler system or outside water faucets. Then in theory you would have
more water flow inside your house while watering outside and more water flow
In my case I want to eventually install a lawn sprinkler system, so I would
prefer a 1" main.
Note: My city requires a 1" main for new service and I think replacement of
existing mains as well.

I agree. I've suffered the misery of having a 3/4 inch line.
I recommend you go with 1 inch line up to the slab.
By the way, that line in the slab will eventually clog with sediment
and need replacing or bypassing. Don't worry, it is not that big a
task. A jack hammer and boring tools will make short work of it.
I live on a farm. When I ran my waterlines from the well to the
buildings, I started out with 1". The barn and one shed have 1".
When I ran the line to the house, I ran out of the 1" pipe, it was
Sunday and the stores were closed. My neighbor had some 3/4". I was
in a hurry an wanted to save a buck. BIG MISTAKE !!!! I have forever
regretted it. There just is inadaquate pressure at the house.
Actually, the pressure "INSIDE" the house is fine for normal sinks,
toilet and shower. It's the house outdoor spigot that is much slower
when I fill the livestock tank for the horses behind the house. It's
just much slower than in the barn, and on a freezing winter day,
standing in the snow with a slow hose is really annoying.
You might save $10 or $20 on pipe and fittings, but the trenching
costs hundreds if not thousands of dollars, not to mention the work
and the mess. DO IT RIGHT THE FIRST TIME.
Personally, since you are already digging it up, put the 1' thru the
slab right to the main shutoff and be done with it. This will save
one more underground splice that could leak later. Note: Forget the
"slab" pipe, run the new line thru the concrete block wall a few
inches above the slab. (much easier).
Heh, all these stories about how 3/4" isn't enough. I have 5/8" coming in
which was reduced to 1/2" shortly after the meter.
My water pressure is fine.... as long as only one fixture is open at a time.
I planned on replacing most of the plumbing and only using 1/2" to feed off
of the main, which was going to be kept at 3/4" throughout. I wonder if I
should just think about having my main changed to 1". Then they could change
my crumby 3" main sewer line while they're at it. I can't believe turds can
flow through there. :-D
