    I need to replace my old shower valve and I already have a very good new Riobel pressure balance valve that is for a tub and shower. Can I just plug off the bottom outlet which would go to the tub faucet and use the top outlet for the shower?

    Riobel - Thermostatic Control Valve

    Do you have a coupe of flow valves as well?

    Does the thermostatic also control the flow? You better check the specs - all these things work a little different.

    I am not sure what you mean by the thermostatic but it does have a ball valve adjustment on both the cold and hot line in.

    Plug the tub outlet (1/2" plug - use the right one for your valve) and it becomes a shower only valve.

    The tub outlet is often bigger. If you have one shower head, the shower outlet is fine. If you are planning more than one, it may benefit from using the tub outlet to feed the shower heads. As long as you provide more flow than the head can use, it won't make any difference...it's when the flow is restricted too much does the performance of the showerhead drop off, so for one, the top outlet if more than enough and easier to plumb.

    The "ball valves" are NOT control valves they are servicing stops. The handle on your valve has to turn the water flow on and off or you will have to install flow control valve. But if the bottom is marked "TUB" then it would almost have to control the flow by definition, in which case either plug it or connect it to the shower riser.

    Riobel Waterproofing Needs

    Looks like a lot of the Riobel Stock only has one outport valve. Integral flow value part of the design.

    These are nice fixtures - my only beef with the line is the tub fillers and the washer kit for them. Often we get dripping when installing them. I have learned that the rough in needs to be so perfect. As low as you can go. Too high and it fits but holds the washer off a C Hair. Then the tub filler drips after use or when the hand held is used. Keep it tight to the tub deck and your golden....
