From the diagram it looks as though there is a screw in the center that
needs to be removed and that may be what is keeping the remaining parts
secure. However I don't see that screw in your actual photograph. According
to Big Jake the escutcheon does not need to be removed on this particular
valve and the diagram appears to support that claim. However I am wondering
what role that big round piece which is probably behind the escutcheon plays
in all of this. The escutcheon is probably just stuck to the wall from
caulk. If you want to remove it, try getting a small flat screwdriver or a
putty knife behind it and gingerly work your way around.
I have found that plumbing instructions, like electrical instructions are
written for people who already know how to do this type of work so no great
detail is provided.

Hi John, Joe, Jake, Joseph, etc.
That big round brass bonnet turns out to be fundamental to the cartridge
removal process! I called Delta again this morning (800-345-3358) for one
of my most amazing customer support phone calls.
First off, I didn't have to press 1 for English (why isn't that always the
default!), second, they answered the phone right away (wow!), third it was
a human who answered (woo hoo!), and fourth, they knew what I was talking
about without me having to ask for the next level of support! Amazing.
Simply amazing. I went from cursing Delta to loving Delta in a single phone
What Delta customer support told me on the phone was the following:
- No need to remove the escutcheon (unless we need more room)
- No need for any tools (except, in dire cases, a strap wrench)
- She called the set screw a grub screw & said it was 1/8 inch allen head
- She said I described the Delta 1300 or Delta 1400 series faucet
- The parts and procedure are the same for either shower faucet
The key is the brass bonnet ring (as you surmised):
- The brass bonnet ring spins off counter clockwise by hand
- If it won't spin by hand (it didn't for me, but, I'm not that strong)
- She said to soak a rag in a 1:1 solution of warm water & vinnegar
- Let the rag sit on the brass bonnet up to four times
In tough cases:
- If it's won't turn off by hand, she said DO NOT USE CHANNEL LOCKS!
- She was adamant about not using any two-point pliars!
- She said pliars don't apply even 360-degree pressure
- She said the only tool recommended is a "strap wrench"
- I'm not sure what a strap wrench is, but, I guess it's like a really tiny
an oil filter wrench of about 1 1/2 inch diameter.
- Once you spin out the cartridge, buy a replacement cartridge
- Reassembly is as simple as spinning the cartridge back in
- The cartridge is Delta P/N RP19804 for both faucet types
- She said it's at Lowes, Home Depot, Ace Hardware, Best Hardware, etc.
Well, I guess we know the answer. Spin out the bonnet. I am off to Ace to
see if I can find a tiny strap wrench after work today. Wish me luck!
Good luck! That cartridge will likely set you back $30-$60. You
should probably be able to replace the two rubber "cups" for less than
My channellocks are 4 point, but I understand their concerns. I have
distorted a brass ring badly enough to have to replace it.

Hi Big Jake,
You were right on the money. On all counts! The Delta Monitor cartridge was
$50 and the two rubber cups & springs under them were really all I needed
to stop the leak.
I tried both the new cartridge and the repair kit and, guess what, they
both worked fine - so I returned the $50 cartridges and opted for just
replacing the two rubber cups and springs below them. I also replaced the
two small washers on the hot/cold water nipples on the cartridge, and the
large O-ring on the outside of the cartridge.
Overall, the job was easy once I removed the brass bonnet ring with a strap
wrench! I did make a few mistakes though. For example, I turned on the
water to test but I had forgotten to put the bonnet ring back on, and the
cartridge shot out of the wall a quarter inch or so spewing water
everywhere until I could shut off the main water supply.
Also, the hot became cold and the cold became hot, so, I had to reverse the
way I put the cartridge in the wall. But, overall, once that bonnet ring
was off, it was a piece of cake. The bonnet ring is deceptive because it
looks like it's part of the main brass assembly, whereas, in reality, the
bonnet ring is in addition to the main brass assembly. That's what threw me
To repeat, we did NOT have to take off the escutcheon. The only tools
required to fix a leaking Delta Monitor single handle non tilt shower
faucet were the 1/8 inch allen wrench to remove the grub screw holding the
handle on and the strap wrench to remove the soft thin brass bonnet ring.
I'll post some pics so the next person benefits from our work!

Thanks for the kind words.
I very much thank you and Big_Jake, Joseph Meehan, Caloo Clay,
JoeSpareBedroom, hchickpea, and Gordon for your wonderful advice.
It's nice to know there's help out there when you need it!
And, now, there's the answer so the next person has the benefit of what
we've learned together!
That would have worked, I'm sure, as with the strap wrench, the bonnet
easily spun off (I couldn't budge it without the strap though).
Here, so everyone benefits, are the additional photos showing the entire
repair (http://www.flickr.com/photos/donnaohl ).

I hope the next person with a leaky Delta Monitor single valve non-tilt
shower faucet can benefit from our discussion here.
