Falcon 19 footer - 1986 - newbie with questions

Finished a project for today. I installed a toilet sprayer. It is hooked directly to the cold water line and is always on when the water pump is on. If you've ever had an RV with a toilet sprayer you know how handy it is. It makes cleaning the toilet fast and easy. I can also use it to spray off dirty things outside the rear doors. Total cost was $39 in parts from the local hardware store. I could use the shower as a toilet sprayer but it's not as convenient.
