American Standard Push-Pull Shower Valve Hot Water Flow Problem

[Peter O]

I have a American Standard Push-Pull shower valve which was installed in 1967. I am experiencing a reduced hot water flow rate relative to the cold water rate. I verified that the hot and cold flow rates are identical on the sink faucet in the same bathroom. What is causing this? I have attached a picture of the valve. If I purchase a rebuilding kit would this correct the problem? If so does the kit come with instructions or do I just remove the two screws on the front and then replace all the parts?

Do you know what kind of pipes you have inside your walls? Your problem could be tied to that. If you have galvanized pipes, that could be the reason for your problem.

Regardless, rebuilding, or better yet replacing the faucet would not be a bad idea.

The two screws are there to hold this rough in tight.

Kits come with instructions, probably printed in China, which is not an English speaking country. Most of the times they are too difficult to follow for the inexperienced.

Those two screws hold the operating mechanism to the valve body. The mechanism is very simple, so unless the cam has worn on the hot side, there should be nothing obstructing the flow. A rebuilding kit MIGHT cure it, but no way to tell until you try it.

The pipes are copper.

I am assuming that once I remove the two screws that the valve will separate. I can then remove the old parts, soak the body in some CLR to remove any scale and then install the new parts. Do you see any difficulty in my approach or am I missing something?

hj,

I located both the rebuilding kit and cam so I will replace everything at the same time and hope that it works.

HJ: Do you still have the parts from the American Standard Push Pull Shower Valve pictured near the top of this string? I am trying to obtain a valve body (the brass housing in which the push-pull item slides). Please contact me to let me know one way or the other.

I do not have that part number, but I doubt that anyone would have anything other than repair parts, not the entire brass housing.

The rear housing is still available. Am,Std. # 29100-07. The front housing is # 29102-07 is obsolete
