View Full Version : Problem with tub spout

01-17-2017, 06:26 AM
Hi guys,

I am trying to install a new price phister tub spout. It is a push on type. The instructions said for copper to be cut from finished wall at 3 7/8. I did that and could not get the faucet pushed on all the way. I tried multiple times. It was 5/8" shy from touching the wall. I called customer service and they said cut 5/8" more from the pipe. I did that and now the spout will push flush to the wall, but it leaks water when the diverter is activated for the shower.
Thoughts ???

The cut off dimension should not change regardless, so I'm thinking they may have advised you poorly in cutting it beyond their own spec, but it might still work because there's usually some built it wiggle room.

These typically seal with and oring in the spout sealing around the outer diameter of the copper pipe. It's possible that oring is damaged. It's also possible that the oring has no surface to seal against.

If there were sharp edges on the end of pipe, I'd suspect the former. A little silicone grease on pipe prior to installation facilitates installation, and that may have been original problem.

After tightening the set screw on the bottom, I am still able to move the spout. Is this normal ?

Ummmm, no. Movement should be slight if any. The set screw typically pushes a bar sorta thing against pipe and should clamp snugly to supply line. I have seen a poorly attached (behind wall) feed pipe cause some movement.

Is the movement in and out kinda all around?

Don't go nuts cranking down on that set screw, you don't want to distort pipe a bunch in case you need to add length back.

how would I add length back to pipe ?

Josh, it's not a sure thing but if there's enough room inside of spout, one might be able sweat a coupling really close to wall. You'd want a heat shield to keep from damaging surface. I'd see it as a last resort.

With a little measuring inside of spout, you should be able to tell if it's necessary in your case.

That's what I meant I didn't think a copper coupling would fit inside spout. What a PITA. This is the first push on spout I have dealt with. I don't think its supposed to be this hard. SMH:shrug:

Is the actual pipe fitting leaking or is the diverter less than 100% effective. The diversion mechanism typically uses a design that is hard to make completely effective. I have seen cheap diverters that leaked more out the spout than came out the shower head.

If the diverter just doesn’t perform well, you might want one like this (

Water leaking out back out spout, especially when water is diverted to shower because of more pressure.
It is not a cheap spout.
Again the directions called for pipe stub out of 3 7/8"
I cut pipe at 3 1/4" because I could not get pipe to seat to the wall all the way.

The extra 5/8 cut from the pipe shouldn't matter. Every one of those things I've installed had the o-ring in pretty close proximity to the wall. I'll ad my vote that the o-ring was damaged and needs to be replaced. Make sure there are no burrs on end of the pipe and that the pipe is polished with fine steel wool before the spout is slipped on.

The set screw has nothing to do with the leak. :)
