I have a single hand pull out for my shower. I have to turn to the C for the hot water and the H for the cold. Is there any way to switch this?

Your water-lines weren't messed with, were they?

Not at all. The only thing I can think of is that the Hot and Cold markings on the new setup is opposite of the old.

Could be. But when you call for hot or cold, cold is coming from the left side, and hot is coming from the right?

The cartridge may be in upside down. I find that far more likely than the water lines being switched, and should be much easier to change.

I'm not so certain that an upside-down cartridge could be causing that. After all, the cartridge is basically two holes; I'm not seeing how that will "re-direct" the water, unless I'm missing something here.

A number of manufacturers market shower/tub shower valves for back to back installations where you do not need to cross the pipes over each other in order to rough the valves in.

The big three who construct the valves in this manner are Moen, Grohe and Kohler.
