depending on your spout diverter if its a valve or is it on the spout it self, if the diverter is on the spout then your diverter is not letting full flow of water out of the spout and its putting enough pressure to allow the water out of the shower head, I had this problem before and if you change the spout it should fix the problem. If you have a 3 way valve which is on the wall then i would suggest replaceing the parts in that valve if possible other wise change out the divert valve. If your broke like me and want a cheap fix then put either a water flow resistor or a shutoff right before your shower head.
The shower diverter is loose or broken inside and needs to be changed.
It's usually due to a combination of two things: back pressure from the shower head, aggravated by the newer low-flow shower heads, acting against a slight leak at the diverter valve. I find that it gets worse after I've been away for a few days and assume that there's scale build-up in both places... the shower head and the diverter. You can try using a descaling solution on the shower head and/or checking that the diverter valve is seating properly and possibly greasing its seat with some silicone grease.
It's the part of a tub control that makes the water go to either the faucet or the shower.

1- plugged shower head 2- defective diverter
That's the way they are designed. Most people do not want both at same time.
vnthe Indiana tub faucets i have here on the diverter stems they have two flat sides on them and there is a special socket to remove that stem i got mine from a company called wil-mar once you have the tool the stem will come right out and there are two washers in there to replace
A two way should be enough.
The piping has to be the exact same length for each shower head from the tee where the cold and hot water feeds from the top of the diverter faucet.
It causes a meteor shower
Isolated showers are when it is positive for the shower to continue through out the whole period of time :)
