In response to Re: tub/shower faucet question
The pipe openings are the same, but the drilled openings inside them where the water comes out are much, much, smaller. The bigger one is where the water comes out and the small one,which goes all the way through the valve is the one for the shower riser. If water flowing from both heads when the valve is in the undiverted status is not a problem then it will work, but the water in the shower riser will create a condition that simulates the back pressure of the diverter and will force some water out the "shower" opening and thus out whatever is connected to it.
: : : : When the diverter is used in a tub/shower the water has to flow out of the spout freely. Any restriction, such as additional elbows will cause the water to back up and come out of the shower head when the tub is being filled. But when I use one for just a shower, I either install it upside down and reverse the core or connections, or cap the shower opening and run the tub connection to the shower head, since that opening allows greater flow than the one dedicated to the shower riser. For your purposes you would not need a diverter, but rather a multiport transfer valve so you can turn on whichever head(s) you want.

: : : : : I'm installing a shower stall and have been researching faucet options. I'd like to have a regular shower head as well as a "rain fall" one. I know I can buy a separate diverter to use with the 2 devices. My question, why can't I use a valve that has a diverter built into it? The installation instructions say the "tub spout" should be a straight drop with only a 90 and that you shouldn't substitute something for the tub filler. Why is that? I don't have an issue with setting it up properly. I'm just curious about the logic. Is there a "real" reason or is it so you buy another piece?

: : : I have not noticed that there is more flow from the spout opening than from the shower although it could be true. Are you sure hj? I think you could use a single handle diverter valve to switch between the heads. hj is describing a two handle value diverter method which does allow water to come out the head when you only want the tub. Some cheap diverters will constrict too much as will excessive water pressure.I have not connected my two heads this way but it sounds like a good idea. I am getting requests for multiple shower heads.LonnythePlumber

: : OK. I'm not trying to pit you guys against each other here. The reason I'm wanting to use the one fixture is looks. I like having just the single handle. I also am not trying to go "cheap". It would cost less to just get a shower faucet and a "multi port transfer valve". I'm looking at the Delta model 6616-PCLHP HK37C-PC $ 373.25. (linked below) I was thinking of attaching the "tub spout" to the regular shower head and then push the button to make the "rain fall" shower work. If, it's not a good idea, it's not a good idea. I'd just like to know before I make an expensive mistake.

: hj and myself are just discussing your innovative idea. I have not considered or tried using a diverter valve but it sounds good to me. How about you hj? Perhaps you could email the Delta engineers.
: To hj. Both the spout and shower outlets are the same size. Both openings are 1/2" ips or sweat.LonnythePlumber
