Shower Pipes

Our existing shower has a piece of 3/4" pipe that extends 20" above the rough-in for the shower control with an end cap. This piece of pipe is on both the hot and cold sides and is fastened by a Tee with one side coming from the supply, one side going to the rough-in and the other side going to the 3/4" pipe. The remainder of the supply is 1/2". What are the 3/4" lengths of pipe for?
|| ||
---R---
| |

This is what it looks like, | = 1/2" supply, --R-- is the rough-in and || are the 3/4 Inch pipe.
Thanks for the assistance

Sounds like plumbed air chambers to help prevent pipe hammer and knocking.
Without being able to see it, it's hard to say. Don't know what else it would be.

Shower Pipes, another question

Are they worth leaving installed? We are installing a new rough-in for Delta Jetted Shower with two body jets and shower head. Couldn't find any reference to this type of plumbing arrangement.
Thanks

They're hammer arrestors and can only do good, especially where you have sudden water diversion like at a shower/bath or appliance valve.
