A tub spout that keeps dripping after the shower control is turned off needs a diagnosis before choosing replacement parts. On October 16, 2026, John Ciampoli Plumbing inspected that problem at a Carlsbad property. The service record documents a faulty cartridge in an older Delta shower valve, significant calcium buildup and a cartridge replacement. These photos show the removed part and stages of that repair.

What caused the dripping in this Carlsbad shower?
The reported symptom was continuous dripping from the tub spout while the shower control was off. The technician identified a faulty cartridge in the older Delta valve and documented significant calcium buildup in the valve body and around the cartridge.
With the building water supply shut off, the technician removed the trim and cartridge. The work then involved locating the correct replacement, cleaning the existing valve body and installing the new cartridge. The record notes visits to two supply houses to obtain the needed part.

What was replaced, and what did the final check show?
This visit replaced the cartridge inside the existing shower valve. The service record does not describe replacing the complete valve or remodeling the shower. After installing the cartridge, the technician reinstalled the trim and checked the repair once water was restored. No leaks were observed during that check.
The installed-cartridge photo below was taken before the trim was reinstalled. It documents a stage of the work, while the service notes document the later leak check. A different symptom or damaged valve body could require a different scope after inspection.

Why matching the shower cartridge matters
Delta's repair-parts guidance lists different cartridges for different tub and shower valve series. Its product-identification tools and parts diagrams help match a replacement to the installed fixture. The brand name alone is not enough to select a part.
If you already have the model, an earlier invoice or installation paperwork, make that information available to the technician. An accessible photo of the handle and trim can provide context, but it may not establish the exact internal part. Avoid ordering a cartridge solely because it resembles the removed one in this article.
What to tell dispatch before a dripping-shower visit
Describe whether water continues to drip with the control fully off, how long it has been happening and whether other fixtures are affected. Mention a stiff handle, visible water around the trim or any previous repair as separate observations.
For an apartment or managed building, identify who can authorize the repair and coordinate access and any proposed water shutdown. Our Carlsbad visit required building-water coordination; that does not mean every cartridge repair will require the same arrangement.
- Give the property city, the affected fixture and the current symptom.
- Share an accessible photo and any known fixture model without removing the handle or trim.
- Tell dispatch about active water escaping beyond the tub or shower area.
- Ask the service report to record the work performed, the final checks and any remaining recommendations.
