 Slow water drip (Newport)- bad valves? which ones?
Author: jochickabee (CA)

New shower- < 6mo of use. We do have hard water.
Brasstech Newport Brass Model 1-744

I have a 3-way diverter and separate thermostatic valve. Water (very slowly) drips even after turned off >48hrs. So I think it's more than just residual water in the pipes.

I closed off the check valves (5 turns clockwise), but even after doing so, I can turn on the water with the diverter valve.

Does that indicate bad check valves? Isn't that supposed to turn it off completely?
Is it possible I have bad check valves AND a bad diverter valves?

Also any tips on how to remove a stuck on brass stop ring? Its just plugged in.

If you turn off the cold feed for the water heater and the drip stops, then the hot stop is bad, in addition to the diverter. If the drip persists with water heater feed off, then the cold stop(and maybe also hot stop) is bad, in addition to the diverter. The picture shows some grey stuff in the 9-10 o'clock position of the ring. Is that just a water stain or did the installer use an adhesive?

by "check valves" do you mean the service screw stops on the sides of the valves?

If you turn them off and the diverter still turns water on, is that water coming slowly or full blast? you made 5 turns clockwise can you turn it any further? What happens if you turn both stops off, turn diverter on, let water flow, then continue to turn the screw stops clockwise or counterclockwise, does the flow increase or decrease corresponding to the position of the screw stops?

Thank you for the response.
I am going to try and replace both valves. (or at least clean them out and see if that is the problem).
No adhesive. It's just pushed in tightly into a plastic thing that has teeth....

Yes the screws. It seems close to full blast. At this stage, I plan on removing/cleaning or replacing the valves. I haven't experimented with turning the screws.

I had messaged the company who eventually replied and otherwise didn't recommend experimenting with turning it more than instructed.

 Newport Brass - resolution
Author: sum (FL)

I just happen to come across an old discussion (on some gardening forum fifteen years ago!) about Newport Brass shower dripping that may be relevant to what the OP is experiencing. I cut out the useless in between posts but hopefully this may be useful.

[ORIGINAL POST BELOW]
I have just had a new Newport Brass showerhead installed in my new bathroom and the darn thing won't stop a very slow drip.

When it is first turned off, it drips quite a bit for about 1.5 to 2 minutes and then it becomes a slow drip that is hard to even see at times as you have to look at just one spot on the showerhead to see the water accumulating.

But the last time we had the water on was Wednesday and it is now Sunday and it is still dripping...we rarely actually see it drip but the floor continues to be wet.

Initially, when this happened, the plumber thought it was caused by a new type of water restrictor valve so he came and took it out. It continued so he ordered a new valve from the store and replaced the valve...the second valve turned out to be worse than the first so he put the first one back in. At first he thought it was just slow to empty out the water in the neck as it is a rather horizontal, long (6 inches) neck, but I think this is too many days, isn't it? I don't want mildewy shower floors. I asked about the possibility of a different valve but he said that we are limited to using the NB valve as others won't fit.

Has anyone else had this experience with NB or any shower head...any ideas, suggestions, etc? Thanks!

[FINAL RESOLUTION POST BELOW]
I just wanted to update this post in case anyone else has this problem. After four or five visits from my plumber and two visits from the Newport Brass rep we finally solved the problem. The cartridges were replaced several times and didn't improve the situation and the screens were replaced twice and didn't solve the problem. Finally, we were just about ready to tear through my brand-new pantry and try installing a whole new shower valve when the rep asked us to try one more time to replace the screens. Apparently the screens come with a little tube of oil that is usually rubbed on the screens before installation--well, this time they decided not to rub the oil on and bingo! the water held and no more drip! I don't know the specifics of my shower valve but I was told that it is the most common valve used, one made by the same company for almost all showers. My plumber, the local plumbing supply store and the NB rep all said that while they had installed this valve jillions of times, this was the first time they had seen this problem. It did occur to me that perhaps it is less noticeable in showers which are used every day because it was such a slow drip and they conceded that that might be the case but still thought it unusual that they had never seen a similar situation. But anyway it is now fixed and I can't think of a better place to post our solution than here to share with anyone else who develops such an "unusual" problem.
