I am installing a water powered backup sump pump which works on
pressure. My water pressure isn't that high About (38psi at a faucet),
but a guy I know who lives on the same street had one of these
installed (by a plumber) and said it worked fine. My pipe is all 1/2"
in the house. I was going to install a 3/4 fitting at the water meter
and use 3/4 pipe for the backup pump. And I was going to put a reducer
going to the rest of the house from the meter. I was wondering if I
should run the pipe up and along the ceiling. The pump is going to be
across the room in the basement. I assume it's stupid to run it low to
the ground and possibly against code? I am trying to keep it as
straight a run as possible. But, right now, i'm looking at a few turns
and of course the rise from the meter to the ceiling.
I have read and heard (even from plumbers) that increasing the
diameter of my pipe will get me more pressure. I have also read and
heard that doing so will only increase volume. Thanks

A larger pipe will not give you more pressure, but will increase the flow.

It will give you more pressure for that same flow rate. If you
start out with a given pressure at the beginning of a pipe, the
pressure at the end will be less as the flow rate increases. The
larger the pipe, the smaller that drop will be for the same flow rate..

I'd run the pipe as you would any plumbing job. The shorter the
distance and the less elbows the better. And I'd run it along the
joists, not across the floor.

Till you go back to 1/2" line. Pressure is set by your location, relative
to the standpipe/pump that supply the water.
Was going to say check water pressure at the meter, but others on your
street have the same problem.- Hide quoted text -

any chance of relocating the sump with pump closer to the meter? have
you talked to the water company they may be able to up the pressure
some

another overlooked issue.

often homes sit above ground level, like where the street is lower
than the basement level.

ideally the sump could drain to daylight, like running a line to
street level.

gravity tends to be highly reliable, sure the ditch digging might
require a backhoe but its a one time expense if done right, using
quality materials like schedule 40 pipe.- Hide quoted text -

The pump is in the front of the house almost towards the center and
the sump is in the corner of the back of the house. �The h2o company
wont up the pressure. It's a pain. I would like to take a shower with
some pressure too. I know I could install a booster, but I shouldn't
have to (nobody should). They do the stupidest things sometimes like
make all the newer toilets low water consumption. I had to alter my
valve to let more water in. Sometimes my # 2's wouldn't even go down!
Gimme a break! How much is a water bill? Let's try and save energy ,
not water!- Hide quoted text -

have you removed the flow restrictor in the shower head?
