my foundation shifted 1/2 inch during the dry weather, by applying
additional water, it has corrected itself. i now notice a reduced
water flow to one side of the house, the flow to the baths and laundry
are normal. could the shifting have pinched a pipe? can the input
and output lines be snaked with a video camera to see if my suspicions
are correct? tia, inputs/advice appreciated.

I'd start by digging to expose the water main entrance. If the pipe
got pinched when the foundation shifted it probably happened right
where the pipe enters/exits the foundation. If you're lucky, and the
pinch is on the outside face of the foundation, you'll be able to chip
away some concrete to allow you to cut the pinched pipe and splice in
a new piece with some couplings. If it's on the inside face of the
foundation, under the slab...well, then you're not lucky!

But if it's pinched at the main service entrance, then why is the
water flow only reduced to part of the house?

Hmmm....right....well in that case, he's _not_ lucky!

It is more noticeable on those outlets near the supply point.

The main or for that matter should be soft rolled copper ( any copper
under ground) It is extremely soft and could get pinched. But if one part of
the house is normal it would not be the main it would be under the slab
somewhere or might be something else causing the problem. it's hard to
determine without knowing how it was plumbed.
But what I'm more curious about s this statement "my foundation shifted
1/2 inch during the dry weather, by applying additional water, it has
corrected itself." I would like an explanation of that.

clay soil was not evenly moist around the foundation, one side
expanded, the other side contracted. following the thread, i doubt it
is external of where the supply line enters the house, it must tee off
someplace, the right side of the house has a normal water flow and the
left side of the house is greatly reduced. i need to know if the spot
can be pinpointed to minimize the area that will have to be torn up.

You say foundation shifted- can you see signs of a crack? If you can
follow where crack may have occurred in slab, you may get 1 axis of
where problem lies. Trace as far as possible entire supply line
plumbing of house- can you figure out how it is routed? You may be
able to get 2nd axis, at least approx. I have a feeling, though,
that you're going to be calling somebody.

there are no cracks in the foundation, and i don't know the routing of
the plumbing, i have always been sure i would have to call someone, i
just wanted an idea of what technology was available and what to
expect. thanks all for responding.
