I definitly think there is a connection between excess urine and CAH. A while back someone posted an excellent medical explanation about how "water follows salt" detailing why salt-wasters tend to get dehydrated quickly and need more fluids. It was a great post. I wish I would have printed it out so I could repeat it here. My son drinks more fluids and urinates more than any child I have ever seen. It has to be connected to the CAH.
