Everytime I flush my upstairs toilet and it starts to refill, I get a double knocking sound. I replaced the ball/fill valve and added an arrester, but I still have the noise. I bleeded the pipes several times using different methods; shut-off main and open lines starting with closest the main line and reverse order when main back-on; shutoff main and drained lines and then closed all lines and turned main back on (suppose to restore air to the arresters?).
Any ideas?
I also cut a hole in the wall to see if any pipes were loose. Didn't see anything.
