Hi
Pic shows 2 bath addition to house approx 12 years ago.
No problems until... within the last 6 months there was a leak under
The slab between " A & B" in picture.
Instead of busting slab, I decided to re-route the copper lines from
Point A... up to attic, then back down to point B.
So alls OK until last night when I closed the faucet at location C.
I heard a noise never heard before, and from reading around here,
I think it may be what's called water hammer.
From what I could tell, sound was near location B.
ALL water fixtures in sketch have air chambers. (or had air chambers)
The newly routed lines going up from H/W (hot water unit) no longer have the air chambers ( side sketch - copper though attic ) I just didn't think of it.
Should I have installed an air chamber where the 90 deg turns down to location B ?
Or any ideas of why this has started after 12 years or after 6 months of new lines.
Thanks
Danna
