the plumbing is like a large L the top of the L being the kitchen faucet. the bottom of the L is the shower/sink and the right bottom of the L is the tub. If looking north up ... the L would be upside down.
Just bizzare both lines are affected and ... it suddenly started knocking and rattling. Literall one night I heard it loud and clear.
There is no air in any of the inside fixtures...however ... right outside the exterior wall of the shower is a hose spigot. That hose ... spits out air. I don't know where or why but ... it spits out air everytime i turn it on.
I'll cut the wall ... surgery !
Thanks for the input. First time cutting into a wall ... wish me luck.
edit: forgot to mention these lines are probably over 50 years old.
If it's your first time in cutting wall it will help to make your lines were to cut first by using a level in some cases if the peice comes out nice and clean and you have studs there u can pop the piece back in should fit snug this way you done have to put plywood or luan.
The outside spickit will do that with air or any ball valve the difference is.... faucets have cartridges for the pressor that comes out of the line, shower body's have cartridges if it's single handle or if it has hat and cold there are what you call stems
Which do the same thing.
Just FYI and good conversation topic lol
