General plumbing question
 

I am running 1/2" copper lines in a crawl space to a double sink I am
installing... My question is this... Is there a "general height" at which
the 1/2" lines come out the wall....I am thinking about a foot off the floor
should be good. Is there a general rule of thumb? Also in saving elbows my
hot water side will come through the gyprock on the right hand side instead
of the left...should that really matter? I personally don't think so..
Thoughts?
Thanks... Jim

If you have the bathroom cabinet, best to place it up against where it will
go and see where the best place for the pipes will be. If you are too
accurate with where the drain comes out of the wall, it might come right out
where a drain from a sink is coming down for example.

Or a valve might get in the way of a drawer. Or be too high and hard to get
to with a wrench once the cabinet is in place, etc.

Saving elbows??? Are you serious? You are talking about your house plumbing.
What can an elbow or two cost?

With today's copper prices, probably $1.45, then there is the frictional
flow / pressure losses...

Jim-

Do the job right....hot on the left / cold on the right.

Supply lines come out of the wall at about the same height as the
drain.

Too high makes access to them (hidden by the sink) more difficult,
too low and they're behind all the stuff in the cabinet.

A foot is kinda low...I'd do them at 16" to 18"....maybe even 20".
Check the vanity for a good fit.

cheers
Bob

Face the opposite direction and you should be fine.

If you use flexible hoses from the shutoof to the faucet, it's not
critical which side they come out. afoot above the vanity floor is
probably 16 or so inches above the room floor.

Even if that WAS true!!!!!

Mathematically ...................

1 divided by 1.1 (to represent a reduction of 10%) ten times = 0.39 or
roughly 40% of the original amount.

OR: If you wish,

1 multiplied by 0.9 (10% percent reduction each time/elbow) ten times
= 0.35 or roughly 35% of the original!
In other words 90% of 90% of 90% etc. etc.

Not ten times 10% = 100%.

To put it another way; suppose one had $100 and told your ten
relatives that you would give the first one you met 10% of the 100,
that person would get ten dollars. The next one you met you would give
10% of the remaining $90, or $9. The next would get 10% of the
remaining $81, or $8.10 etc. etc. After the tenth relative there would
be $34.86 left over?

Or have I missed something?

The pressure won't be lower unless there is water flow!!!!

First, go to the store and see how long are the flex tubes
from the shutoff to the sink. That will make some of the
decision.

I'd want the hot on the left, just cause it's standard.

And you don't want the next buyer of the house to question the while plumbing
system?

Wonder if the inspector would say anything about this?

Yes.

I almost have two doctorates from Drexel University in Engineering.

I'll have to remember to hold that against any job applicants with
degrees from there.
