Loose drop ears. Why and what's the fix

Hey all.
I posted this over at My buddy Terry's site but wanted to give you guys a crack at this. I have had my drop ears come loose on multiple showers. I never have had this problem prior to 3 years ago. What changed then you ask? I started using pex.
When installing I make sure to to level and square up the pipe coming out of the wall. Then a week later the fitting is wobbling. I mostly use kiln dried lumber. I am assuming the wood is shrinking.

So what's the fix? I want to continue running pex from valve to head. Thinking about getting a bunch of 6" square brass or bronze plates. Then brazing the drop ear to that, then screwing this plate to the blocking.

What are your thoughts?

Let's resist the urge to of saying not to use pex on the tub supply.

The plumber I use won't use Pex between the valve and shower head, he says that valve manufacturers don't recommend it because it restricts water flow.

That said, the Pex line is a lot less ridged than copper so it doesn't take much movement of the shower head/pipe to loosen the screws. Have you tried using 2- 2x4 blocks with longer screws?

How long are the screws you're using?

I'd ask the same, what is your blocking and how is it being fastened. Then what screws are you using to fasten the drop ear?

I use 2x material and use 4 - 3-1/2" screws toe nailed in. For the actual drop-ear I use the 3 holes and also screw it down. No nails for my backing or attaching the drop-ear.

I saw these cleats on a recent project. They seemed pretty sturdy to me.

With the weight of shower heads today, most plumbers in my area use either a 3 hole drop ell or mount the two hole ell vertical instead of horizontal.

I too wonder how you are fastening the drop ears. I honestly don't see how they can come loose if properly fastened. I've never had a call back, not that that means anything necessarily. All of the Pex drop ears I've used have three holes, and I usually use 1 5/8" cement board screws to fasten that to solidly fastened 2x material.

I have seen plumbers use nothing but a pex talon to secure a drop ear, or a single nail.

Some plumbers use these for a shower drop too. They are really flimsy...

Speaking of drop ears don't ever think you're smart and use one for a tub spout... don't ask me how I know.

Same here, trying to reinvent the wheel, what a disaster that could have been

I've accessed the mounting screws by just removing the nipple and using a 6" driver. Can you do that on this?

So what's wrong with using a (non-PEX) drop ear 90 on a tub spout?

Thanks,
Wayne

Not sure Wayne, I've never seen a non-PEX drop ear. I would think it would be fine.

I used a 1/2" PEX drop ear one time with galvanized nipple to thread my tub spout on. 3 screws solid as a rock! Then...at the END of my job I put all the plumbing on and ran the tub. Had water dribbling out the shower head (shower rise)and lower than normal pressure. After calling my plumber, wondering why this was happening, he asked about a drop ear.... I said yes. He went on to inform me he had also tried it one time thinking he was awesome, and how much smaller the ID of PEX restricted flow.

After tearing out the wall behind my shower and fixing it... I don't do that anymore.

While you can use pex to the showerhead, the outlet of the valve to the tub spout must be all full-diameter pipe. All of the instructions I've seen specifically call that out, but not everyone reads them!

IMHO, I'd never use galvanized there, either. It WILL start to rust eventually, leading to a rust stain. Either run copper and put a fitting on it if you want to thread on a spout, or use a brass nipple. The easier thing is probably to use one of the Delta spouts that can either screw onto a nipple, or an adapter soldered onto a copper pipe, then, the spout screws onto that adapter. It's much less fussy about getting things the exact length needed to get the spout tight against the wall and oriented properly than most other methods (except, probably a slip-on spout). A slip-on one is fine as long as you ensure you've cleaned up the end so you don't slice the O-ring slipping the spout on, creating a leak.

Bottom line, using pex anywhere to the tub spout in a tub/shower, is asking for problems...it will back up into the shower head unless you have a positive diverter in there...and, the smaller ID of pex means the tub will fill slower, too.
