Hello:
I purchased the following pump and tank (signature 2000 well pump with "pro source plus" pressure tank)
I have a 1800 gallon cistern in my basement with a sears jet pump hooked up to it.It is starting to go bad and you can hear the pump run in the house.
What i would like to do is hook up the submersable pump so i won't hear it and also to get a little more pressure.
A couple of questions i have is.

#1- Do i have to put the pump in a piece of 4" pvc pipe or can i just free stand it in the water?

#2- Can i put this pump in horizontaly?

#3- What kind of check valves,float switches,ect. do i need?
It would be greatly appreciated if someone could show me a diagram on how the setup should look.
THANK YOU KEN
