I took out our new 2017 Reflection 26RL right after picking it up from the dealer from another state we were traveling through. After taking the first shower I noticed the shower faucet was leaking and there were visual signs of water in the storage saddle under the 5th wheel section. I took off the cover plate to the faucet and could see a big crack in the diverter tee. I can't get it into the local dealer due to their schedule until mid October. I need to use the RV again in the coming weeks and was just going to replace the diverter tee myself. However, I don't see how to remove the entire faucet from the shower. I expected there to be an access hole to the back of the shower from the kitchen cabinet, but don't see anything. Do you need to remove the shower walls to replace this? I have not tried just removing the diverter tee without removing the faucet as I'm afraid of breaking something. Any suggestions?
