I am helping a friend replace the two bad main valves in his house. The pipe is 3/4" and we will use a threaded ball valve. He wants to raise the valve up higher.
What's the best way to do this? Can we use a long nipple? If so is galvanized a bad idea?

Thanks.

A nipple is no longer called a nipple when it becomes longer than 12", after 12" it is considered a pipe. Use a brass nipple and 2 pipe wrenches.

Gagecalman since you want it higher I guess your looking at a 12incher or 18 inch piece . If the 90 at bottom is galvinized might just leave that short brass nipple there and couple on to it. looks like pvc in basement or cpvc above if pvc might want to take a look into where its going generaly dosent belong in house

He was trying for 18" higher. That's not a brass nipple. Just rusted.
I was hoping to come off of the 90 with an 18" pipe and then the valve. Can't find brass that long.
Is galvanized a bad idea or against code? The service will probably fail before the new 18" pipe does.
That is CPVC but there is also some PVC. I'm replacing that as well. Thanks!

"Is galvanized a bad idea or against code? "

Actually galvanized is NOT against code BUT I once had to testify against a plumbing company and found that ferrous and nonferrous piping shall not be connected on water lines without protection

After finding this little note I was able to prove the plumbing was contrary to code

In actuality, all galvanized supply piping has a brass valve for isolation but the fine print says dissimilar metals must be protected from galvanic action (corrosion) by use of a dielectric fitting or nipple

On steam work, you will see a black pipe with brass valves and same with gas piping it is only galvanized and nonferrous metal that this is more pronounced

I would't install galvanized anywhere for anything. The new galvanized nipples that I've seen used in tub spouts have huge rust in them really quick.

Easy to make up any length of pipe too in copper. As long as you provide the proper separation between disimilar metals as Sylvan pointed out.. We use a minimum of 6" of brass nipple to transition between steel and copper.

I purchased a 10ft section of 1/2 brass pipe for a project and just used a hand threader to make my own pipe sections. Its really soft material, so its really easy to work with.

I don't know why but earlier I couldn't see the second picture . after seeing more of the work ... I'd still run the galvanized or rip out a bunch of plastic , Galvanized is very strong can take a beating , temporary work exposed is perfect till the job gets done right (re pipe)
BTW Very nice work Tuttles!
