I just purchased a 2 handle faucet for a bathtub. (American Standard Cadet/Colony 2 handle bath/shower set)

For the connection that goes from the hot/cold intersection down & a right angle out to the tub spout, instead of using a length of copper going down with a threaded male adapter on it & using a right angle soldered connection to a soldered lenth of copper going into the tub, I'd like to get something with more strength in case someone pushes down on the tub spout to lift themselves up, they don't break any connections.

What if I buy a 1 piece brass length with threads on each end, and put that into a brass 90 degree angle connector with threads on each side, and for the length that goes into the tub spout, use a length of copper with a threaded male adapter on it? That way in case someone pushes down on the tub spout to lift themselves up, the absolute worst case will be I can put a new length of copper with a threaded male adapter on it, thru the wall into the threaded brass 90 degree fitting.

Would that be a problem?

I really don't want to use just a copper length going down & into a 90 degree soldered connector on both ends to a length going into the tub spout.

Is going from copper ---> brass --> copper asking for trouble?

 

That will work well. I have done this on occaisions where the customer asked to do this, with the exception that it was all brass to the spout.


But the way you describe will work fine.

 

Would I have a problem if the spout was copper instead of brass? (I'd rather have brass there too, but I need to cut the 1/2" pipe for the length of the spout)

Any expansion/contraction problems with brass & copper meeting at a threaded joint?

Also, would you put anything on the threaded joints other than just teflon tape?

 

No expansion or contraction problems at all.



You can use copper; majority are copper in installations, brass is usually used after someone has broken a tub spout for the very reason you describe.


Any threaded connection I install, I use teflon tape and teflon thread sealant, especially on gas lines.

 

Thanks very much for your replies!

One last item I'm considering that may get me in trouble.

Instead of soldering on shutoff valves on the hot & cold water pipes that are going to go inside a bathroom vanity, would soldering on a threaded male adapter, and then getting a threaded shutoff valve get me in trouble?

My logic is when/if the valve ever needs replacing, I can just turn the water off, unscrew the old one & screw on a new one.

 

If your shut-offs are going into a vanity base, just use 1/2" compression valves.
Good luck!
