Proper order of water components.

Here's how the water comes into my house:
(Street)-(Water Meter)-(Backflow Preventer)-(Expansion Tank)-(Whole House Filter)-(Home Plumbing).
My question is, do those components have to be in that order?
Can the whole house filter be before the backflow preventer?
Can the expansion tank be after all the other components?
I'd like it to be Meter----WH_Filter----Backflow Prev----Expansion Tank.
Thoughts?
The backflow preventer is there because the city requires it.

If the utility requires the backflow preventer, they want it to be the first thing after your meter -- and certainly before the filter, which can be a significant source of contamination.Br. Jamie, osb

Good point. I had no idea water filters could be a source of contamination but it makes sense.
Is it possible for me to put the expansion tank last in line after the filter? Or does the tank have to be close to the backflow preventer?Homeowner, Entrepreneur, Mechanic, Electrician,

Tank can go pretty much anywhere on the house side.Br. Jamie, osb

Tank needs to be downstream of any BFD. Usually they are located at the cold supply to the water heater.
Check with your water provider see if they require a back flow device, if so, some will supply them no charge as they get funding to upgrade their systems.
Keep in mind the BFD may require yearly testing, could be $150 or more to have it recertified yearly. Some water providers will levy fines if you do not test and document yearly.Bob "hot rod" Rohr

Yeah we get it tested yearly now against our will. Haha. I would like a larger one considering the incoming pipe is 1 inch and they have a half inch preventer hooked up now.
Maybe I can get them to give me a new oneHomeowner, Entrepreneur, Mechanic, Electrician,
