Some filters are not durable enough to withstand water hammer from a valve downstream of them, so the safest configuration is what gets recommended.

Hookup Order - Backflow->Regulator->Filter->Valve

Every manufacturer's dripline setup guide or drip kit shows the filter and regulator installed after the valve output side. What is the reason for this configuration (besides some filters not being capable of handling supply line pressures) If one were to connect a regulator and filter on the supply line side of the valve they could save money by not having to buy filter's and regulators for every valve.

I've had my lower garden drip system hooked up for 4 months with this configuration (Shutoff Valve-> 140psi rated filter-> Automatic globe valve) with no problems so far. Will I have problems in the future with this setup? The reason I'm asking is because I'm installing another set of valves on a much bigger design and I would prefer not to make a costly mistake. Right now my preferred setup would be (Shutoff-> Backflow-> Regulator-> Filter-> AutoValve).
