Tub shower diverter stem on tub spout broke and need to have instructions for how to replace the ROD Diverter seal o ring in the spout.

It sounds like the diverter is not fully opening to allow the water to run to the spout. If the diverter is in the wall, perhaps there is a seal in there that needs replacing. If it is in the spout, just replace the spout,

a lot of shower diverters do this..you may need a bigger seal on the diverter..if you can remove the spout assembly from the tub(with the diverter valve in it) and take it all to the hardware store.. see if they have a different seal/diverter that has a snugger fit but still falls to drain the shower head line out..that will slow that leakage..the spout is on a pipe and unscrews counter clockwise(normally)unless its a single valve unit..with the wide ring around the back..then that calls for a plumber..

the seal on the diverter may have fallen off, or bad/dirty diverter.

when the water is turned off, does the diverter return to "normally open" state? (no divert, goes directly through tub spout)

You can replace the assembly and not have to worry about taking apart the stem or, you can get a replacement diverter. The spout will twist off turning counterclockwise.

Does it have a diverter on the spout? If so, replace the spout with the same type. If it is a new installation, did you make up the valve or was it complete and designed for tub & shower? If it's an old valve and it has a separate diverter stem, there is a spacer behind the valve between the valve housing. Replace it.

Hi,

Trust me... something broke or it would not have fallen into pieces...

Replace the spout!!

The issue might be the tub diverter spout. Most such do not seal well. It is a matter of jiggling the spout knob. It should seal better with a little experimenting.

The shower diverter is not working and needs to be replaced.

The cartridge has 2 or 3 o-ring type seals around it that feed the water through, it picks up both hot and cold and mixes them. Some cartridges are replaced as one, some you have to replace the seals, just take the faucet info to the hardware store and match it up. I think the diverter is for the shower. It sends the water up instead of out.

There is a threaded stem that passes through the spout and attaches to the white plastic diveter valve. If you are starting from scratch (everything apart), you can put it back together in this order:
1) Place the white plastic diverter inside the spout. the circular side with the black round washer should face the the wall side of the shower (mating up against the threads for the water pipe).
2) The stem can now be inserted from the top and into the notched section of the white plastic diverter valve. The threaded end of the stem shoud be outside of the spout (from the top side).
3) A round black washer fits over the threads. It should sit right where the threads end. Dont push it all the way on to the unthreaded portion of the stem.
4) Screw the threaded knob onto the threads.

Should be ready to install now. Including the spout itself, there are 5 parts and are configured in this order from top to bottom.
1) Female threaded knob (the knob for operating the spout)
2) Threaded stem (threads on top)
3) Round black washer
4) Spout
5) Whit plastic diverter valve.

Mine leaks when I turn on the shower, thus reducing shower pressure. I looks like a poor design to me. The stem is not a tight fit in the spout and this allows the diverter to "wobble". The washer on the diverter valve does not seat tightly and allows water to leak out the tub spout when showering. I would replace the spout.
