Pipes are hammering

[Iceman_pdx]

Hello everyone. Just joined cause I need some help. Piping in my house is hammering big time. At first I thought I had to much pressure, I measured it at outside spicket. 80 #. I crawled underneath and found my PRV and adjusted it, but I noticed a Tee ahead of the valve. outside spickets are higher pressure. I guess I shouldn't of measured it there, instead at the WH. So then I thought it might be cause I'm using outside spicket's cause I've been working on the lawn last few months, but nope. I'm getting hammering if I'm not using them, I just flushed a bathroom toilet and lines are hammering. If I go open the kitchen faucet it bleeds air and stops. Same thing if I'm using the outside spickets the house hammers but if I open a fixture or flush a toilet it goes away, but it will come back. Is there something I can install to fix this? I also have water collecting out front near where my main comes in. Its under a monster tree with huge ass roots, I don't know if I have a leak or its something else? Any suggestions? I don't anything about expansion tanks or Areators or probably even how to spell it LOL

Thanks

Looks like I figured it out. In last year I have changed out the WH, and I turned it off and still hammering, but I changed the fill valve out in my master bath, so I turned toilet off and that was it. No more hammering. Looks like I have a bad fill valve or the wrong fill valve. I learned something
