I have a gerber shower diverter, The syem was hung up in the block from the screw that holds the seat washer onto the back end of the stem. I got it out and had to peplace the seat in the block, I also replaced the stem and "o"ring's with new ones. I got it all back together and the water still comes out the tub when you move the diverter to the tub, But, when you move the diverter to the shower It comes out of the shower and the tub spout, Do I have a bad block, or whatever you call where the diverter screwes in? Or is there something I am leaving out?

Thanks.
Brian

First of all did it ever work correctly? Does the diverter pull up from the spout ore is it in the valve body? If it's on the spout about the only thing I would check is the house pressure, Do you have a pressure reducing valve where the water enters your house? Do you know the house PSI? Until I get more information from you I can't say more. Back to you, Tom

Heya Tom, Thank You Sir.
Well I have the valve in the cener of the valve body. I checked further and found that the old screw holding the washer on the back of the old stem fell off and was up inside the valve body. I rem9oved it and tried to regrind the valve seat but it was gone. I replaced the valve seat, stem and washer. But it was still running from the tub spout, and the shower when it was turned to shower, But only to the tub when turned to the tub spout. So I figured that the valve body must have been damaged by the loose screw. Not wanting to tear down the wall to replace, I removed the old tub spout, plugged the valve body, and installed a diverter spout, and it seems to have worked well.

Oh yes it works gret since I installed the tub diverter, thing is if I want to make the tub diverter in the valve body I would have to tear out the wall and replace the valve, I know it was a quick fix, but it did work well. I pull the tub diverter and the shower works well now. Withut the added expence of tearing out and rebuilding a wall.

If you turn the center diverter knob to tub and leave it alone it should work exactly like a two handle valve with a diverter spout.
I don't believe that little screw hurt anything unless you cranked down on it when it was on top of a seat. And speaking of seats what exactly was it that you replaced. Was it the diverter seat or a hot or cold valve? So, are you working OK now? Let me know if I can help. Tom

It was the diverter seat that I replaced. I replaced the valve "stem" and the seat as well, but it was still coming out of the shower head, so what I did instead of replacing the whole valve block in the wall,and tearing out and reinstalling the wall and tile. I opted to just install a diverter tub spot that diverts from the tub spout. It worked great.
See I run an apartment community with a few hundrad units, and time is of the essance. That's why I took the easy way out for that. I have tons of leaks and stuff breaking down as these units are very old.
The diverting tub spout got me through the state inspection.
I must say that I have run into this problem quite a few times since, the diverter stem is stuck in the valve, the only thing I could come up with is the screw falling off over the last 40 or so years and that is what is causing them to get stuck in the valve block. They are old set up's hot water valve diverter stam in the middle and a hot water valve. And for some reason the diverter stems seem to allways be stuck inside the valve block. Haven't quite figured out why, so I did find the screw inside the valve block.
And assumed that was it, and the seat was totally destroyed as well, but if any one has an explanation for these old gerber diverters, I would be so happy to hear from you lol.

Hey Brian,
Kudos and congrats for resolving your problem the easy way. Thanks for the update. Tom
