THE SHORT ANSWER
Does it stop, or keep replenishing?
A few after-use drips can be retained water leaving the head. Some overhead heads release it later, so time alone cannot diagnose a fault. Water that keeps arriving while the shower is off, or a changed pattern, needs model-specific assessment. Identify where it escapes and whether you have a mixer or electric shower before buying a head or valve. Water from an electric unit’s casing is a separate safety concern: stop using it and arrange qualified help. An identified electric-shower PRD discharge also needs a no-use and model-specific service route.

Is the water from the head or the shower unit?
An outlet drip into the tray is different from water escaping from a wall unit, backplate or electrical area. If an electric shower is leaking from its casing, stop using it, keep clear and contact the maker’s service team or a suitably qualified professional. Do not open the cover or run it again to locate the leak. Spreading water or water reaching electrical equipment also needs prompt help; in a rented home, notify the landlord or managing agent. If a Triton electric shower is visibly discharging from a PRD outlet identified in its exact model instructions, stop using it and arrange model-specific professional service. Triton says not to use it again until the PRD has been replaced. Do not open the unit or replace the PRD yourself. If you cannot tell where water is coming from, stop use and ask the maker or a qualified repairer.
Compare the pattern without dismantling anything
| What you notice | What it can mean | Next step |
|---|---|---|
| A short after-use release that settles | The head may be draining retained water. | Record whether this is its usual pattern; no part needs replacing solely because of it. |
| An overhead head releases another small amount later | Mira describes delayed drain-down in some deluge heads. | Compare with the installed maker’s guidance; do not use a fixed number of minutes as a fault test. |
| Dripping continues between uses or the pattern has changed | A shut-off valve may not be sealing; timing alone does not identify the part. | Record the off-state pattern and arrange model-specific advice. |
| Water appears from casing, backplate or electrical area | This is separate from retained outlet water. | Stop using the electric shower, keep clear and obtain qualified help. |
| Water discharges from an identified Triton PRD outlet | Triton distinguishes its small clear outlet tube/plastic elbow from casing leakage and head drain-down. | Stop using the shower until the model-specific PRD has been replaced by an appropriate professional; keep the unit closed. |
| I cannot tell where water comes from or what shower I have | The safety and repair route is uncertain. | Stop using the shower and leave covers and connections alone; ask the maker or a qualified repairer. |

A mixer and an electric shower have different internals
A mixer takes hot and cold water from elsewhere and blends them. An electric shower heats a cold feed inside its own unit. Use the existing manual, invoice or a safely visible external model name to identify yours; a wall box or temperature dial alone is not enough. Pumped power showers and digital systems need their own instructions. This distinction helps the service team choose the right assessment; it does not prove the fault.
Why can a shower drip while it is off?
There are two different water routes to consider: water already retained in the head, and water continuing past a valve that should have shut. Mira describes staged drainage in some overhead heads; Triton identifies model-dependent flow-control or solenoid faults for continuous off-state dripping. For mixers, a valve or cartridge failing to close is another possible explanation. A plumber or manufacturer must establish the cause for the installed model.
A new showerhead may miss the problem
Cleaning jets or replacing a hose washer addresses different symptoms from a shut-off valve passing water. This guide does not recommend those as a cure for a continuous off-state drip. Avoid ordering a cartridge or solenoid from appearance alone; ask what fault was found and which exact part fits.
Make one useful observation, then choose the next step
Start with a safe, dry view
With the shower already off, look only from a safe dry position. If water is from casing or near electrical equipment, stop the observation, keep clear and arrange qualified help; do not operate the shower again. If a Triton electric shower is visibly discharging from a PRD outlet identified in its exact model instructions, stop using it and arrange model-specific professional service. Triton says not to use it again until the PRD has been replaced. Do not open the unit or replace the PRD yourself. If you cannot tell where water is coming from, stop use and ask the maker or a qualified repairer.
Describe what happens between ordinary uses
Record when you last used it, whether dripping settles or continues, and whether the pattern is new. Do not keep switching it on for a test, tilt a fixed head, detach the hose or block the spray. Delayed drops from an overhead head are not by themselves proof of a leak.
Find the model without opening it
Use a manual, invoice or safely visible external marking. If unsure whether it is mixer, electric, power or digital, say so; do not remove a cover or trace concealed supplies.
Check the next step and outcome
For an unchanged after-use pattern that settles, compare your maker’s drain-down advice. If water keeps dripping between uses, changes substantially, or remains unclear, contact the maker, installer, landlord or plumber. A useful outcome is a clear report and assessment route, not a home diagnosis or a replacement part guess.
Read the advice that matches the symptom
Mira’s overhead-head explanation and Triton’s off-state/casing advice cover different patterns. Use the exact shower’s support information; linked fault descriptions are not permission to open or repair the unit.

What should you tell the plumber or manufacturer?
Give the make/model if known, where the water appears, whether it settles between uses, when the pattern changed and any recent installation or plumbing work. Include warranty details before authorising work. Ask whether attendance and fault-finding are covered, what the proposed repair includes, whether parts, labour and VAT are included, and what happens if the symptom returns. There is no verified comparable all-in price here: head replacement, mixer repair and electric-unit service are different jobs.
After professional work, ask the person doing it to demonstrate the installed model’s correct shut-off and explain any normal retained-water drainage. If the original continuing drip returns, contact them with the same symptom record rather than repeating internal repair attempts. A little water released from an overhead head is not necessarily the same failure recurring.

Questions about a shower dripping when off
How long should a showerhead drip after use?
There is no universal cutoff. Some heads drain soon after use; Mira describes delayed release from certain overhead heads. The installed head’s guidance and a continuing or changed pattern are more useful than a timer alone.
Does an electric shower have a cartridge like a mixer?
Do not assume the same part or procedure. Triton describes different flow-control or solenoid mechanisms depending on model. An electric unit needs its own service route; never open it to identify a part.
Will descaling stop it dripping while off?
Not necessarily. Descaling does not establish that the shut-off valve closes properly. A persistent off-state leak needs its cause assessed; no generic descaling or washer replacement is offered as that repair.
Can I keep using a leaking electric shower?
If water is from the casing, backplate or electrical area, do not use it or switch it on for a test. Keep clear and obtain qualified help. A drip from the head needs a different assessment and is not enough to declare the unit safe.
