Diaphragm Pump Before or After Ez Pure System?

I have two uses for the pump.

  1. To Pump pre-filtered water from my holding tanks for smaller jops, eliminating the use of the EZ pure/setup tear down garden hose ETC.

  2. To give the extra boost/pressure to feed through my 400 feet of hose.

Now when it comes to the later, I have had some “over pressuring” results with the pump after the filter, I was wondering if it would be ok to put it on the inlet side of the Ez Pure. I might go get a smaller pump later, but it does work fine for now. It just hard to get the perfect spray distance with my adjustment knobs.

If i remember correctly the EZ pure is good for 400 PSI? The pump is rated at 100PSI output max
