Delta R10000-UNBX Reviews

Rated 5 out of 5 by from Great valve body Replacing a valve body can sometimes be tricky. This was not the case on this installation. We pulled the 30 year old valve and installed the new valve in less than thirty minutes.

Rated 4 out of 5 by from Caution See Reason for 4 Stars Below: This is a 3 way valve. If you plug the wrong hole you must buy a $70-100 part to convert it into a 6 way valve with 3 functions. Delta gets 1 star!: This came as a part of a Delta Complete Shower Package. Be warned, Delta doesn't include the Shower Body Rough In (the main part).

Rated 5 out of 5 by from Thanks, I needed this! Thanks for advising me to get this for my Delta Shower. My husband was mad I purchased our shower without HIS I was thrilled when my plumber told him I had EVERYTHING to complete my shower installation. Made my husband realize I CAN do some things without his help. You made me PROUD!! Thank you for all your help. I would recommend everyone to listen to your advise.

Rated 5 out of 5 by from Solid Product Delta has been a leader in quality products for decades. As usual, this is another one. Instructions are good for the Do-It-Yourself crowd. The main reason I purchased this product was its ability to give me adjustments for both water temperature and the force of the shower stream. Many valve bodies today do not allow both.

Rated 5 out of 5 by from Valve body No plastic here! Brass all the way and the scall-guard works perfectly. Installation was not a problem at all.

do I need this for the Delta rain showerhead or is this for a tub faucet

This is the rough in valve for a tub and/or shower. This is what controls the water flow (on/off/temp)to your system whether it is to a shower head or tub spout. You need valve trim that attaches on the outside of the wall to this rough in valve.

Is there anywhere that is open on Sunday tomorrow and I can pick it up since I need it tomorrow?

We are only an online company that doesn't have any stores to pick up from.

What trims are available for this valve body?

The Delta R10000-UNBX is the rough in valve for almost all Delta shower trims. There are very few Delta trims that do not work with this valve.

whats' the difference between R10000-UNBX and R10000-IP?

The difference between the Delta R10000-UNBX and the R10000-Ip is the connection type. One Sweats onto 1/2" C.W.T. and the other threads onto 1/2 IPS.

Is this valve compatable with the Brizo shower trims?

Unfortunately, no. This is not compatible with Brizo.

what is the difference between the Delta R10000-UNBX and the Delta R10000 IPWS

The Delta R10000-UNBX has externally threaded ports and the R10000-IPWS has internal threading.

What is the flow rate, at 40PSI, of this valve?

The Delta R10000-UNBX has a flow rate of about 8.0 GPM.

Why do I need the R10000-UNBX and also the R11000 diverter rough-in? What is the function of each?

The Delta R10000-UNBX is a standard shower valve. You will use the R11000 if you plan to divert the water to another source (i.e. handheld unit, etc.).

Will R10000-UNBX valve work with T17255 trim?

Yes, the Delta T17255 is compatible with the Delta R10000-UNBX.

Can I use this valve body with a Moen fixture? It appears identical.

No, valves & trim are very manufacturer specific & will not work with the trim or valve of another manufacturer. You will have to get a Moen valve if you'd like to install Moen fixtures.

What is the difference between the Delta R10000-UNBX and the Delta R10000-UN?

Functionally there is no difference in the two models. The BX indicates a single box model.

What is the difference between the R10000-UNBX and R10000-UNWS? I'm planning to purchase the T17T055-RB shower control.

The Delta R10000-UNBX 1/2 Inch Rough-In is the same as the R10000-UNWS 1/2 Inch Rough-In, but the latter of the two has a service stop at the valve. This means that if you had a leak or if you were servicing another fixture in the bathroom, you could just turn off the bath/shower and still have the function of the sink and toilet or whatever other fixtures you have. With other valves, you would have to turn off the main water supply. If you need to shut off water to the valve, you just remove the handle and there is a flat-head screw to turn.

Will this connect directly to 1/2 cpvc using solvent, not requiring any adapters?

The Delta R10000-UNBX will connect to 1/2" supply with out any adapter. If you look at the installation guide under the product details it will go through the full process for installation. Let me know if you have any other questions.

Is this pressure balanced

The Delta R10000-UNBX is not pressure balanced but it does work with thermostatic trims.

Is this valve low lead compliant?

No, the Delta R10000-UNBX is not low-lead compliant.

Will water flow first to the tub spout below this valve and then up to the shower when the tub spout diverter is closed?

Yes that is correct it will go to a tub spout first.
