One Reply to “Black Crap!”

  1. Mind if I ask the specifics of the chemical going through that pump supply hose and check valve. I have some ideas depending on what that may be depending on whose product and what the name od the product is and it’s use. If there is no chemical online for this and it is water only, I have only seen something similar to this once and the cause at that particular site was an abundance of Iron in the water and a very high PH causing the brass to corrode and leaving that black goo. If you are running reclaim through this system, look no further, that is your culprit. Take care.
