Ok as promised, i PTFE'd all the joints this morning...........No leaks.....from the joints

But i am from the top of the 2 filter housings

I noticed it came with"two"filter seals(one black/one white) in each housing. But it leaked when using the two, so i took one out from each filter housing and it's "still" leaking slightly. I dont understand it.... I'm tightening the joints well, but not too tight..... Do i need 2 seals per housing?



? It's an RO man 200gps system............Any help,soooo appreciated. Thanks, Dino
