Zoeller Filter, Septic Tank

Is it easy to remove? the whole assembly i mean. i'm concerned if i give it a try and the tab snaps into place i won't be able to remove it.

Is this filter sized to insert into a 3" pipe or 4" pipe?

Can you put a pipe on it so you can remove it and put it in ? What the out side dimension as thin pipe and sch 40 different .

I have the yellow tuff-tite unit. will this drop into the same standard outlet tee, or do i need a special extra-long outlet tee for it?
