Thank you for your question. We do offer many different kinds of R10000 rough in valves and it depends on what kind of piping you are using as to which one you use. Here is a list of what all the letters mean after the R10000 number.

UN-universal valve can be used with copper, iron pipe, pex or cpvc piping
BX-is an individual box instead of a case of 12 rough-in
WS-screwdriver stops means you can turn the water off at the valve instead of shutting off the water in the whole house.
HF-high flow valve can only be used with a shower only faucet.
T-thin wall mounting kit included.
IP-can only be installed with a iron pipe.
PX-can only be installed with pex piping
MF-used for pex cold expansion connections

Thank you for your question. Delta Faucet model # R10000-UNWS can have the tub port plugged if you are not using a tub spout. We do not supply the plugs. It is a 1/2" pipe and if you contact your local retailer or wholesaler, they should be able to supply you with the appropriate plug.

Thank you for your question. There is not really a chart telling the differences between the rough-in kits but I will certainly pass along that suggestion to our marketing department. Thanks for the suggestion.

As to the differences in Delta Faucet model # R10000-UN and R10000-UNBX, there is not a difference in the model itself. The difference comes in the packaging. The R10000-UN has to be ordered in cases of 12 and they are packed together. The R10000-UNBX is one individual box.

Thank you for your question. Delta Faucet model R10000-UNBX can be used for a shower only application by pluggin the tub port. Model number R10000-UNBXHF is for shower only applications and if you would like higher flow from your valve. If you already have the R10000-UNBX, you can use it for a shower only application.

Thank you for your question. I apologize that you are having an issue and by your description, it sounds like you are having shower rise. This can occur when any of the following situations are not followed:

1) The distance between the tub spout and valve has to be between 8"-18".
2) Copper or iron pipe is the only thing that can be used between the tub spout and the valve.
3) There can only be one elbow from the valve to the tub spout.

If any of these are not followed, you will have shower rise until the problem is corrected.

Hi Ed!

The difference between the R10000-UNBX and the R10000-IP is the type of pipe used in the installation. The R10000-UNBX can be used with copper, pvc, pex or iron pipe; whereas, the R10000-IP is made specifically for an installation with iron pipe.

Thank you for your question. Delta Faucet model # R10000-UNBX needs a hole size big enough for the valve to fit through but not too big so that it can't be covered up by the escutcheon plate. You can use the plasterguard as a guide. Included here are the instructions for installing your valve. The measurements to the finished wall are on page 2.

Thank you for your question. Your Addison tub faucet contains a rotational limit stop. that may need adjusting to allow more hot water to flow through the valve. Included here are the instructions for adjusting the limit stop. The first one is if you have a 1700 series faucet with a temperature knob and volume control that are separate. The instructions are on page 9.

The second set are for the 1400 series faucet with only a temperature contol. The directions are on page 8.
