OK I had 1 company drill the well, and a plumber install the pump and make connections 2 years ago, should have one company do it all. So when the well kicks on I get orange sediment that my 5 micon does not stop 100%. So I installed a second filter, little help. So I need to talk to the plumber and ask several questions. Is there a second check valve and is there a "torque arrester"on the pump this is the item I don't know is the correct terminology. I have read the thread about start up sediment and hammer effect. Also does the second check valve have to be installed vertical.
