Thanks for all of the suggestions.

I am just a rookie when it comes to the DIY but I am learning. I just have a few questions for you guys.

1) What is the "ALDA"? Where is located? What does it look like?

2) What is the "IP"? Where is it located? What does it look like?

3) What is the switchover valve? Where is it located? What does it look like?

Thanks again and sorry for the basic questions.
