Shower head fell off and won't go back on

There is no single magic bullet here. Since this is a new trim, I have to assume it is a new valve as well. If the head drips for a long time well after the valve has been shut off, my first impulse is to think thie installation is with older galvanized plumbing as the water supply source and that some particulate was knocked loose during the process of installation. There are no O-rings that can be replaced that will remedie the problem in any case.

Since your problem seems to be on a newly installed valve, if particulate is your problem the replacement cost will be on you, otherwise it could be a warranty issue. 99.9% of the time it is not the product but the quality of water that runs through it. It is a reflex to blame the product.

Having said that, there are more questions than this forum allows to narrow down the possibilities. Be advised that if it were my valve I would have no reservations about replacing both the cartridge and pressure balancing cartridge since they work together and sold separately, While mass produced items do have failures, when it comes to plumbing, as i said, it is usually what is in the water that causes the problems.

I would make an access panel on the back side of the shower, this way if I ever need to access the shower lines/fixture in the future I can do so, Hope this helped Tim, here is a website that may help:
