Re: FHB176-Replacing a Shower Mixing Valve. Don’t you need to install air chambers above the water supply lines? I am bidding on a project where the customer wishes to save the “mud-set” tile and replace the existing two handle valves. However, I was told that all the interior walls are concrete block with a skim coat of plaster. Is it possible that the plumbing wall would be packed solid? The 7 story high rise building was built in the early 1950’s and is located in Evanston, IL. I have yet to open the wall.

Did you send an attachment?--couldn't open.
No, I was just bumping your post to the front of the discussion listing again to increase it's exposure.
No attachment was included. It is just a service to the forum as a way to repay my educational expenses.

How'd you get Piffins signature line?
Seemed proper for the copy/paste procedure of the puter.
Once something has already been posted anywhere on the Taunton's boards, as example a photo, all that is needed is a copy/paste to place it on a post here, without the need of an attachment.

Air chambers are not need except by solenoid type valves, ie a dishwasher or a washing machine.
Actually in michigan "air chambers" are no longer allowed. You have to use the fluid filled (or mechanical) Arrestors.
Some places air chambers are legal But I don't recommend them . They fill with water in 28 days.
Mechanical hammer arrestors are preferred but in some locals the code requires access to them .
Like someone already posted they are not needed on shower valves.
