After, but I do have one before as well. One pump actually broke on me because it sucked in a piece of a filter pad. I don't use filter pads but i ordered pods online and they come in a bag that has a filter pad. I didn't want to sit there removing each pod sine I ordered 2000. To make along story short it got sucked into the pump, once the impeller couldn't turn for too long while still getting power the motor burnt out. I then got another pump and it took literally 4 min to install since i had the true union ball valve.
