💨 What’s Normal Spluttering?
When releasing near-boiling or boiling water, taps often “spit” slightly. This happens because superheated water flashes into steam as it leaves the nozzle. A light hiss or brief splutter is completely normal and built into QETTLE’s safety design.
⚠️ Main Causes of Splutter
- Steam expansion: The main reason - boiling water forms bubbles that disrupt flow.
- Air in the system: After installation or filter change, trapped air can cause extra spluttering until flushed.
- Limescale build-up: Hard water scale narrows outlets, making splutter worse.
- Old or blocked filter: A saturated cartridge can restrict flow and cause irregular spurts.
🛠️ Easy Fixes & Prevention
- Flush the tap after filter changes to clear trapped air.
- Service filters regularly (usually every 6–12 months).
- Descale if needed - EcoFilter can service the tank and cartridge housing.
- Check installation - ensure hoses and vent pipes are correctly fitted.

❓ FAQs
Do all QETTLE taps splutter?
A little splutter is normal whenever boiling water is released. Heavy or constant spluttering indicates a fault or service need.
Will a filter stop spluttering?
A fresh cartridge helps by ensuring smooth flow, but boiling taps will always spit slightly due to steam expansion.
Is spluttering dangerous?
No - QETTLE taps are designed with child-safe handles and multi-stage outlets. The splutter is a byproduct of safety venting steam.
How can I reduce spluttering?
Keep filters fresh, descale regularly, and flush the system after cartridge changes or maintenance.
