    I'm renovating a bathroom and relocating fixtures.

    In the case of the tub I am not happy with the new anti-scald valves and want to reuse the existing tub/shower valve body.

    1) As I understand the code the anti-scald requirement is for the shower and not the tub. Can I reuse the tub/shower valve body for the tub and put some kind of intermediate valve between the diverter and shower head? If so do you have a suggested product?

    2) The valve body in my existing tub/shower is close to 60 years old. It is solid brass. Are there reasons not to reuse the valve body assuming I can replace or refurbish the removable parts?

    Thank you.

    Mainly, for a valve that old, the availability of repair parts is marginal at best. If it is mainstream like Am Std, someone may still make stems. But handles and trim may not be available at all. Do you want to commit a remodel job, which hopefully is good for 20+ a valve which already has a death sentence?

    In addition to this depending on the extent of the work performed you may be required to upgrade the valve to pressure balanced or thermostatic to meet code requirements...

    You are having this permitted and inspected aren't you?:rolleyes:

    Post world war II parts?

    With the wall out, you should bring it up to code.
    There are plenty of balanced valves you can choose that give you temperature and volume control.

    And parts will be available.

    It's hard to even get trim and handles for the old stuff anymore.

    It doesn't sound like a "keeper" to me.

    You have to have a real love affair going with that faucet to even consider keeping it. Kohler and Grohe both make a pressure balancing unit that would fit AHEAD of your faucet to make it code compliant, but the flow from your faucet would not be close to what it is now after passing through the device.
