Have a Delta R10000 Faucet and a Delta Escutcheon for 1700 Series cover to go over the faucet. New install on a sterling tub shower. What size hole to drill so as to fit the Cover over the valve Should it be 3" or 3 1/2"? The cover has a black gasket on the inside and a white gasket on the outer rim. Currently there is a 2 " hole so as to fit the valve but the cover will not fit very close to the thin shower wall

Fairly easy to replace. Most just unscrew counter clockwise.

REMOVAL OF STUCK CURVED FAUCET HANDLE WITH HEX SCREW ' DIY Forums

http://www.deltafaucet.com/parts/id-my-product/index.html?reset=true#wiz you should be able to track down the one you have on this "troubleshoot your product
'

There should be a dirverter on the tub spout. It will be either a knob to pull up or a ring to pull down on and hold untill the water comes out the shower head.

If there is no dirverter go buy a new tub spout with one.. The prior owners may have installed the wrong spout.

Your fixture body may be corroded beyond repair. Since you've replaced all the rebuildable parts, I'd suggest you get a plumber to check it but expect that you'll need to replace the faucet. Get a modern "cartridge" (Delta, Moen or Kohler) fixture that can be easily repaired indefinitely.

The only thing that comes to my mind, go back where you bough them and
ask them to make some copies of the installation instruccions.
I know...the pride will get hurt a bit....but you will install this bath in NO time.
Hope this help

check the tub faucet the pull lever maybe slightly faulty causing back pressure in line and pushing water up to shower head --u may have debris in tub line causing partial blockage -or u have alot of water pressure coming in and it is to much for the lines to handle and it is pushing up to shower head

the big round black plastic is part of the installation it will screw to the valve body thats the size of hole the black round cover is also backing plate to round external dress cover so be careful not much leway when cutting the center part should be knocked off but keep on to protect chrome escutcheon take off when applying handle also remember unit is shipped in cold position need to adjust hot water shipped in cold position because of anti-scald system

Remove hot/cold button in handle, remove screw/pull off handle. Remove the two screws in the wall plate/remove plate. Use a wrench to remove the diverter assembly. Get new diverter assy and reinstall eveything. You don't need to turn off the water.
