Water sprays out the diverter

easy way is to install a shutoff valve on the shower head.

Sounds like the delta people forgot to install the diverter piece inside of valve body,small white plastic piece screwed into valve. If you take out valve you should see it up inside body

Call Moen directly. They will ship what you need to your door, for free.

Is there a button on the tub filler? How about the spout on the tub, does it lift up? If there is not a tub spout then it should be shower only, if it has a tub spout it has to have a lifter of some sort, the foto I found showed the little button lifter. Hope this helps.

If your tub spout has a knob that you lift to divert the water to the waterpic then replace it with a Delta service part #RP17453 pull down spout. It always sends 100% of the water to the shower head and will always snug tight to the wall.

If you are handy, the best solution is to call delta and have them send you a new diverter. They will need the model of your faucet. The new diverter will come with instructions on the install process. As far as fixing it without the new diverter, I don't believe you will be able to.

It sounds like it could be manufacture defect. Take it back for a new one.

The only possible explaination is that the water is finding it easier to go up than down. Water is lazy, just like me. ;)

Use an allen key to remove the tub spout. It's underneath and awkward. Once the allen key is loose, the spout just slides off. Try running the water. This may solve your problem and all you'll need is a new tub spout. If not.....

Turn the water off to the house.

Use an allen key to remove the handle.

Use a phillips to remove the trim plate (2 screws). Cut the silicone around the trim if it's there (which, in a proper installation it shouldn't be, but...)

Unscrew the nut (usually chrome) holding the cartridge into the brass body of the valve. The cartridge pulls straight out. Check for restriction in the ports of the cartridge itself. Check for restriction in the line going down to the tub spout. If you can't find anything, replace the cartridge.

Reassemble & Enjoy!

sounds like the diverter is jamed. it may be in the spout or a button in the escheuchon. if spout try to unjam the pull up knob or the pull down ring. if in the escheuchon remove part and replace.

well the Diverter is not working it dose not matter the distance. when applied it should shoot the water to shower or tub if not working will come both.
