Rated 5 out of 5 by from Easy! Simple Pex Installation! Direct connectrions to PEX make this so simple. No sweating of fittings!

Rated 5 out of 5 by from This valve is excellent for condo projects that don't have individual water shut offs for each unit. [This review was collected as part of a promotion.] We install this valve routinely because it has the service stops so you can isolate the valve without shutting down the entire house or condo complex. Huge benefit without a huge extra cost.

Rated 5 out of 5 by from Awesome product [This review was collected as part of a promotion.] Expansion pex ready with stops is the only way to go!!

Rated 5 out of 5 by from Easy to Install Universal Delta Valve [This review was collected as part of a promotion.] I really love Delta for their universal valve system and the fact that they go even further and provide valves that are ready for Pex because that is what we primarily use in our remodeling projects. The less connection areas in plumbing make for a safer and more reliable plumbing system for any home or commercial building. It gives people a peace of mind that their plumbing will last longer. I also like to spec out the valves with stops because it makes for a much easier repair when and if needed. You do not need to shut off the water to the whole home or building or at the main and inconvenience others.

Rated 5 out of 5 by from Easy as 1,2,3 [This review was collected as part of a promotion.] Easy to install! No more soldering connections. Simply expand a few fittings and you are set. I can't recommend these valves enough.

Rated 5 out of 5 by from Quick and easy installs [This review was collected as part of a promotion.] You no longer have to worry about creating a solder connection to then attach pex a expansion. You simply expand and off you go. Saves 30 min of install time.

Q&A

Prior to purchase, I would like to confirm this valve is pex cold expansion compatible on both hot and cold inlets and the riser, but that the drop/tub outlet is factory sealed. What is the martching cold expansion diverter valve model number?  Thanks

Asked by: AJ M
Hello AJ M, Thank you for contacting us, I would be happy to help you. R10000-PFS-MFWS is cold expansion and shower only. The matching shower diverter would be our universal R11000, please see link below: https://www.deltafaucet.com/bathroom/product/R11000 Please contact us back if you have any questions or need further assistance.  Best Regards,  Nicole

Hi,  I am trying to install a Delta Faucet R10000-MFWS, like to know what size PEX are the hot and cold inlets? I tried using Sharkbite 1/2 inch, but it’s too small to get on the inlet, and the 3/4 inch is too big, thus too loose. Thank you.

Asked by: Larry
Thank you for your question, Larry! The R10000-MFWS has 1/2" PEX cold expansion connections and 1/2" universal outlets with male threads. Feel free to contact us directly, if you need further assistance. Best Regards, Benjamin

Will this valve work with PEX A. Not with PEX B Crimp.  I'm only interested PEX A that uses Expansion Rings.  also, I don't need 12 of these can I buy just 1 valve and if so where & Price?

Asked by: Tommy
Hi Tommy, Thank you for your question about the Delta Faucet model R10000-PFS-MFWS. Yes, MF models are for Pex A cold expansion installation. See the specifications for more information: https://media.deltafaucet.com/SpecSheet/DSP-B-R10000-PFS-PX_B.pdf You can purchase Delta Faucet products at many local dealers and internet sites. If a dealer does not carry a specific item in stock, they should still be able to place an order for you. I recommend using our store locator. Actual pricing may vary and is determined by the selling retailer/wholesaler/dealer. https://www.deltafaucet.com/where-to-buy Please contact us directly if you have any additional questions!
