Delta diverter vale R11000 1/2" PEX to tub spout

[Daijoubu]

Delta do not recommend this setup due to flow reduction but I hate tub spout diverter.

Because of the restriction in the cartridge plus the diverter valve (5GPM?) is it worth connecting the spout with copper or can I just use 1/2" PEX?
I do like the 3 screws PEX drop ear, they are nicer smooth machined as opposed to the sweat ones (rough cast)

What about the connection between the R10000 mixing valve and the diverter? Should I also flip the valve? ( Plug shower and use tub outlet)

You have to use copper on the tub spout. Or iron pipe size (brass). Pex is too small. When you fill the bathtub water will trickle from the shower head.

I have done two (both Moen). I used copper. I would stick to what delta says. No one is going to see the drop ear in the wall.

The tub will be connected to one of 3 outlets on the R11000, what Delta do not recommend is using the diverter valve on a tub filler spout.

Moen M-Core transfer valve? Moen actually lets you use their transfer valve with a tub as opposed to Delta and it's rated for 6GPM iirc.

I was also looking at the U232XS valve which has PEX throughout but I've read mixed reviews about whining cartridge and dripping while off.

With the 2- or 3-way setup, there will be no dribble. So fill speed becomes the concern.

Another possibility is to use 3/4 pex, with an adapter at the valve. Then use this drop ear elbow, if you are using crimp/clamp and not expansion PEX. https://www.homedepot.com/p/questio...e-Drop-Ear-Elbow-Fitting-UC342LFA/204492219/1

At the valve, use https://www.homedepot.com/p/Apollo-...e-Thread-Reducing-Adapter-APXMA1234/301541035

Yeah I did look into using FNPT adapter to 3/4" PEX but that and the drop ear you linked to but they are not readily available, I may as well just sweat it, done a few soldering jobs and none leaked yet, just afraid to mess up an relatively expensive valves lol

There are also spouts that take a 3/4 nipple.

Dang, that has become a widely available item from multiple manufacturers.

One thing to look at is the flow rate of the cartridges themselves. I can't find it but when I researched why I had low flow to the showerhead, I found the 13/14 cartridge was restricted to about 2 gpm. I believe the 17 series is higher flow rate but not sure. They also have non pressure balancing cartridges that are not restricted except by your water capacity. I found a link to a place on the 13/14 and 17 cartridge where you can drill it out a little and get more flow. When you open the cartridge, you can see the hole for water flow is only 5/32" for the hot and for the cold. You an drill them out to 13/64" I believe and increase the flow. So what's it matter what size pipes you use incoming to the valve body when the output from the cartridge is only 5/32" for each side??

I've never used pex on a tub spout even with the R11000 transfer valve. The way I set up these has been. Turn on the valve and the tub runs. Then if you engage the diverter on the tub spout you can either steer it to a hand held or a shower head or a rain head using the r11000. In order to have the these function correctly you need to do the tub spout in copper. You need a 10000 and an R11000 to do this correctly. From the r 10000 the tub spout can only be copper or ips.

 

[John Gayewski]

The r11000 valve can also function incorrectly with a tub spout on it. It can cause the transfer valve to switch functions spontaneously. It's a shower only valve.

I'm in Canada so that complicate things lol

Yeah I've seen this, if the flow is too low, I'll drill out the cartridge I guess

I don't want a diverter on the tub spout, the R10000 will only have a single outlet going to the R11000, other outlet will be capped.

My plan is handheld, overhead rain head and tub connected to the R11000

The r11000 valve can also function incorrectly with a tub spout on it. It can cause the transfer valve to switch functions spontaneously. It's a shower only valve.

Really?? How so, the handle will turn by itself?!

Should I just return everything and get a Moen M-core?

 

[John Gayewski]

I'm not a moen guy. I haven't installed one. I've serviced moen and they can be impossible to pull the cartridge unless you have a special tool that moen doesn't sell. Their design is kinda dumb with the really long rubber cartridge that swells up in the body. I've spent hours of my life digging these out in people's homes. I've only had one delta valve get stuck delta uses simple o rings so they pull easier.

The 10000 with a copper tub spout pre installed then the R11000 is the only way I've done it. I have been impressed by how well that system works with everything functioning as it should. I can't say what you should do I only know you should really only install the valves as they are intended. Drilling shit is kinda dumb when there are valves made to do it right. Delta has a valve with a tub diverter in it also but I haven't installed one.

I did a M-Core and a PosiTemp. I did not use transfer valves.
