Hello all,

House has got a 3/4 copper running from the meter to just a few feet
under the crawl space. It then reduced to a 1/2 inch.

Pressure and flow is there but a hair weak when I had more than one
faucet running. Is it worth it to upsize the accessible part of the
piping with 3/4? Some were ran behind the walls, Don't want to tear
out the wall and replace the 1/2 in. behind it.

So, it will end up with 3/4 for most, reduced it to 1/2 just before it
disappears behind the walls.

thanks
richard

Tough to tell if it is worth it without knowing the total length involved,
length that currently is 3/4", and how much of the 1/2" you can replace
with 3/4".

had a poor flow some years go on a hot line to my bathroom. I have
all copper so that wasnt it.

When I finally gott around to fixing it I found it near impossible to
close my ball valve hot to the bathroom

I ended up sticking a piece of pipe over the end of the ball valve
lever and had to rock it to finally close it......

Anyhow when I was done I opened the valve and found gravel came out of
my tub spout. Flow was great

Conclusion:......

There had been a water line break nearby.....

Gravel got into the line and got stuck at the ball valve, slowing the
flow. When I had trouble closing the ball valve it disloged the rocks
which came out the tub spout when the water came back on.

If I were the OP I would replace as much as possible the 1/2 line and
replace all the valves espiclly if they are the old style which have
small passages for the water to pass at the valves
