I do not know why they installed 2 csv's.  I know there was a issue with water hammer when well was installed and they couldn't stop until they installed 2nd csv.  probably a case of pump guy not knowing what they were doing.  now that I am starting to have fitting failures and researching I am asking same thing.  I read the post or sticky about too many check valves.  All I know is it sounds like std practice to install multiple check valves on pump discharge.  i never questioned because i thought they were the experts on this.  You are saying 1 check valve is plenty on any depth well?

thanks for the reply.   Because of the depth of my well I have several check valves in the discharge line but none after leaving the well. I just have 2 csv's before the pressure tank.  Are you saying the  extra  check valves in the well could be causing the issue with fitting failure?

I have two csv installed on my water supply line going to my pressure tank.  They were installed when I had a new well drilled.  The well is 550' not sure where pump is placed probably around 500' level.  To prevent water hammer the csv's were installed.  After several years in service my supply line fittings have had some failures.  the pressure gauge between the two csv's will go to around 110 psi on well pump side until pump shuts down and then shows around 60 psi when pump is off.  pressure tank set to 40 -60 psi.  Is there a way to alleviate this high pressure that my pipe is seeing.  My pvc should be good to 200 psi (sch 40 pipe) but i believe this high pressure is causing my pvc fittings to fail.
