hello everyone! i need some advice/help on a small question. i can not
seem to find this specific step in any how to guides on the net. i
have low cold water pressure and weak flushing in my upstairs
bathroom. i know this is because of the old galvanized piping leading
up to the bathroom, my house is very old. i have found articles on how
to replace the piipes with copper and even how to unclogg the old
pipes. however, the step i am missing and i really need is how do i
know which piece of the galvanized piping to replace. i don't have the
money to replace all of the piping but i saw on a old HGTV episode
months ago where the host showed how to replace galvanized piping with
copper. he did something that showed him which piece of pipe was the
most coroded and needed replacing to fix the problem. it was about a
12 inch or less piece. if anyone could refer me to a web-site or could
tell me themselves step by step how to know where and which piece of
the piping to replace i would be very grateful.

thanks lulu

Often, the restriction turns out to be in an EL
or the side outlet of a TEE.
Personally, I think you are wasting your time
attempting to replace the length of pipe you
think is the "culprit".

BTW, if you do cut out a section of the old galv,
you may find that outlets and switch boxes in the
bath are no longer grounded. That includes the
box and faceplates and exposed screws. Because
in houses of this age the boxes in baths were
grounded to the cold water line. Just a heads up...

I might know the answer but I'm not going to read a bunch of run
together lower case text to find out. If you can type what you did
you can also press the caps key when appropriate and the enter key to
put some white space between differing toughts or subjects.

"Weak flushing?" Whatever you mean by that has nothing to do with the supply
pipes. Maye "slow filling" of the commode tank, but nothing having to do
with flushing itself.

So where is this "low cold water pressure" and how was it determined. A
partially blocked pipe does not affect the pressure - flow rate maybe, but
not pressure.

I'd start by examining the faucets.

If the old galvanized pipes corroding are the problem, which is very
possible, then I think you're wasting your time trying to track down
which exact section of pipe it may be. I can see perhaps if there is
one section that is much older than the rest and easier to access, but
if it's all about the same age, then it all should be replaced.
Trying to find 2 ft that might be worse right now, even if that's
possible, only to have to replace more next year doesn't make any
sense to me. Plus you then have to deal with connecting the old
galvanized, which is failing, to new copper.

just install PEX its cheap, very reliable and easy to work with.

we have half inch copper to our bathroom. if someone is showering and
flushes scald is result

so I am about to run new PEX both hot and cold from the hot water
heater.

a hundred feet of PEX is under 70 bucks. change it all it will be so
easy you can eventually replace all your galvanized lines

Replace the whole line. It's going to happen again.

The OP may be in California which does not generally allow PEX. Seemingly,
PEX is made from whale blubber or DDT or might someday be made with either
of those materials or may leach noxious chemicals into the environment or
start a grass fire or somesuch.

Here's some background.

Agreed. The OP is just one more person who is too lazy to bother with
things which don't seem important to him/her. But, those are the very
things by which people at a distance are judged in most civilized societies.

I wonder how many interviews the OP would get if he/she submitted a
resume in that format. G

***************

But, the thought of trying to find a section of pipe with significant
restriction caused by corrosion buildup poses an interesting question.....

Anyone got any ideas on what principles of physics, thermodynamics or
maybe acoustics might be used to determine just where such a restriction
is located, assuming all the pipes are accessable, but without
disconnecting any of the plumbing?

Opening faucets in the sequence of their distance from the supply point
and noting the flow rates is too easy and answers along those lines
won't be accepted. G

Too much thinking going on. When you have problems with old
galvanized pipe, it is time to replace all of it.

It is my experience that *all* the pipe will have crud built up on the
inside. Not just a small section.

What you can do is start with a new line from the meter. You need a permit
for this. Use the recommended size pipe like 1 inch or whatever.

If you have a basement or crawlspace with easy to access pipes, you can run
a new pipe to the bathroom from the new main line and tie in the new main
line to the old cold water pipes.

If the pipes are in a concrete slab or a small attic which is not
accessible, this will be more involved. Might need to tear walls apart.
Might need to run lines outside around house and then into each room through
the outside walls. All sorts of different situations.

Might want to call a couple of plumbers and see if they can fix the problem
first before going to all this work. Sometimes valves can be replaced and
improve things a bit.

yeah patch sounds good till the pipes rust thru, creating leaks or a
flood.

this happened to a buddy of mine who refused to replace the lines,
leaks everywhere he finally gave in and replaced all the galavanized.

do note flat runs are more likely to crud up, but sooner or later it
all will have to be replaced

practice your dictatorship on someone else..and i am sure your "secret

my this place has become unfriendly lately

The OP comes here looking for answers and a fight breaks out, the
simple solution ignored.

do note replacing sections of galvanized is a big hassle, connecting
to old rusty galvanized must use die electric unions or fast rust out
will occur, and many have learned putting a wrench on old steel pipe
that looks fine can crush it easily.

all in all its way easier to replace a entire run with PEX, today
plumbers dont like that its way too easy to use.

Once a message goes through 5 or more thread iterations, the threads
just become a clash of egos and it is best to just kill file the message.
