City water? There is no practical way to increase the pressure beyond what
is fed to the house. It can be done with tanks and pumps though.
Expensive and may not solve the real problem.
Given that you have old galvanized pipe, there could be a lot of flow
restriction from corrosion buildup. My first thought is to replace it with
Pex. I'd also check on the condition of the feed from the street. No
matter what you do in the house if that line is partly closed from buildup,
nothing inside will improve.
You really need an inspection by someone that knows what to look for and
that can put a pressure gauge on the line.
its probably past time to replace all the water lines......
PEX is excellent and cheap too, the incoming water line may be clogged
too espically if its lead..
the thing about galvanized, it will leak. fix one leak get 2 more
An analogy: You have four worn out flat tires on your car, it just
doesn't perform as well as it used to. You could likely find a solution
such as fitting a much bigger engine or even something more complicated
and still never get a good result or you could replace the tires.
There isn't any real fix for old galvanized piping except to replace it.
Again a bunch of you jump to conclusions without enough facts to
support them. Are the galvanized pipes really his problem? We don't
know because he did not report the actual pressure he has. Instead
suggest he do pressure and flow tests just like a plumber would do if
called out to the house with this problem. All it takes is a pressure
guage and a 5 gallon bucket. Who knows, he might just have a reglator
in the system. somewhere
They close up, but mostly at the turns and after the HW tank.
I've had galvanized in all my homes and never saw a leak.
This house has 50 years old galvanized and the pressure is fine.
I re-piped the scaled up 60 year-old galvanized in my last place, a
Didn't bother replacing the verticals in the plumbing wall, as they
looked good inside.
Worst parts were the first el in the supply, and all the HW supply up
to the veriticals.
That was 30 years ago and I still have family living there with 90
year old galvanized in the walls and good pressure and no leaks.
If I ever get a low flow problem in this house I know where to look.
I've always been on Lake Michigan water, and I understand galvanized
might have more problems elsewhere.
The OP has a problem with one shower.
He should find out why that shower is slow.
A sink faucet screen with some pieces of scale in it can almost stop
the flow, so the same can happen with a showerhead.
Don't know if he has a tub shower and the tub faucets run strong.
He didn't say. That's par for the course.
all depends on the house. I have no pipes covered by sheetrock. A two
story? Yes, it probably would. But pex is pretty workable. If you can
pull romex through a given area, you can probably pull pex through the
same place. If a single level with a basement or crawl space, then it
ain't nothing but a thing to do.
remove the "not" from my address to email
We had our pipes replaced a few months ago using a company called
Repipe Specialists. They knew exactly what walls to open and where.
They tore out the galvanized and installed copper--in one day--in out
split level with 2.5 bathrooms. We had them install all new faucets as
well. After the city inspector checked it out they came back and
patched the walls ready for painting.
My main issue was dealing with ceramic tile. They had to remove tile
in one bathroom and I could not find new tile that exactly matched.
Rather than tear all the walls out I elected to remove about 40 tiles
so they could be reused. Using a Multi-Max and heat gun I was able to
save almost all the tiles for reuse. I bought a few that were a close
match for use behind the toilet. The 60 year old tiles came off rather
easily. Those that had been taken down and replaced 20 years ago for
drywall repair were harder to remove.
increasing the pressure will no doubt increase the risks for leaks....
since the problem is just one shower.
does the shower head have a flow restrictor in it?
is poor flow just hot or just cold?
could be a clogged shower head, galvanized generates particles of rust
that can clog things.
bad shower valve somehow?
