Rated 5 out of 5 by from Water-saving Valve makes pressure independent of temperature I bought this valve because it enables you to set the pressure (flow) of the water independently from the temperature. I hate that all the options from the big box stores require you to turn the water all the way on in order to simply get hot water. I believe in only using what I need, and this valve (combined with the right hardware inside the shower) permits me to have hot water at a much lower flow rate. I'm just now getting again for the remodel of another bathroom.

Q&A

I bought this valve and is it possible to run to the shower and than run the tub spout to a rain head? And then on top of that is there trim kit that can run both at the same time, one at a time? Or do I have to buy a diverter valve?

Asked by: tyler
Thank you for your question, Tyler. You would need an R11000 diverter valve and a 3-setting trim kit in order to divert between a shower head and rain can shower head. The R11000 valve will be connected to the top port of the R10000. Best regards, Jon

What is the difference between this model with PEX Cold Expansion R10000-MF and the PEX Crimp R10000-PX? Is the insert barb bigger in the former than the latter to accommodate the stretched PEX during installation? Thanks.

Asked by: David
Thank you for your question, David! The difference on these models is solely in the connection for the Inlets in regards to the type being used. Both will feature universal 1/2" connections, however the R1000-PX will have slightly tapered inlets for easier installation. Best regards, Edward

i installed two of these rough in valves into my walk in shower. I teed the hots and colds together from original. I don't have a valve yet but plugged the shower head. i noticed that the valve itself is very hot to the touch with no H2O moving through

Asked by: Doug
Hi, Doug. Thank you for your question. The R10000-MF is a solid brass valve body. Any type of connection around the valve body in your wall that gets hot will make the valve body hot. Best Regards, Rosanna

What is the difference between a "box" model and the other roughin valves? Also, what is the difference between a high flow model and non high flow rough in showervalve?

Asked by: Aaron
Hello Aaron, Thank you for your question. The Delta MultiChoice Universal Rough-In "box" model rough-in valves are single model units and non-box models comes as bulk/case of units. The difference between the High Flow and non high flow valves is that there (non high flow valve) a bottom port for a tub spout installation and the R10000-UNBXHF valve does not include a bottom port for a tub spout installation. The high flow valve are designed for shower only installation. Best regards, Tanya

I am trying to trouble shoot my installation of Universal shower mixer. The water coming out the shower head or tube is lukewarm. Do I just adjust the shut off screws?

Asked by: Lucho1
Hello Lucho1! Thank you for your question and we are happy to help! To troubleshoot your Delta MultiChoice® Universal Tub / Shower Rough - PEX Cold Expansion MODEL#: R10000-MFwe recommend flushing the valves with all new installations. The problem you are describing is most likely the result of debris in your supply lines or faucet. Over time, common water debris will settle in the house supply lines. Anytime the water is shut off to a portion of the home, this debris can become dislodged and will move through the pipes to be caught by a faucet. Local construction or the changing of the seasons can also cause this. Flushing the supply lines through the unit should remedy this situation. To flush the unit, we recommend the following: Start with the easy stuff: Remove your aerator, wand or hose to check the flow through the unit without that part installed. If the flow is good, the piece you’ve removed is where the issue is. Soaking the part in a 50/50 mixture of white vinegar and water could help remove any particles or debris blocking the flow. If the water does not have a good flow, the problem could be in the faucet. Next, check the supply lines for debris: Turn the supply off to both the hot and cold-water lines. Once off, turn the handle on the faucet to the on position and leave it there to bleed the lines of any excess water. Next, disconnect the hot water supply line and place it inside of a bucket. Once the line is securely positioned into the bucket, turn on the cold-water supply. Since the handle was left in the on position, the water will flow up the cold supply line, through the faucet cartridge and back down the hot water line into the bucket. Leave this flowing for at least 30 seconds. After flushing, reconnect the hot water line and repeat this process with the cold-water line to ensure all particles have been removed from both supplies. With any further questions or concerns, please do not hesitate to reach out to us directly. Thank you for being a loyal Delta customer. Best Regards, Carrie
