Grohe 3/4" Compact Thermostatic Cartridge (Reversed Inlets) — 47186000
The Grohe 47186000 is an authentic, original-equipment 3/4" compact thermostatic cartridge engineered specifically for installations where the water pipework has been crossed or reversed (hot supply on the right and cold supply on the left). Standard Grohe thermostatic cartridges are factory-calibrated strictly for hot-on-left pipework; if fitted to crossed supplies, the valve will only produce scalding hot or freezing cold water with zero temperature control. Installing this specialized reversed internal element corrects the issue directly at the valve body without having to break into walls or re-pipe the incoming plumbing.
Identification Guide:
MPN: 47186000 (also referenced as 47 186 000) | EAN: 4005176140594 | Fitting Size: 3/4" Compact | Supply Orientation: Inverted / Reversed Inlets (Hot Right, Cold Left) | Includes: Pre-fitted sealing O-rings, integrated stainless steel gauze filter screens, and stop ring
Key Features
- Solves Crossed Pipework: Internally inverts hot and cold porting to allow full thermostatic mixing when the hot feed is plumbed to the right.
- Eliminates Costly Retiling: Corrects plumbing configuration errors without having to dismantle tiled walls or alter concealed copper runs.
- Integrated Gauze Filters: Fitted with fine stainless steel mesh screens to safeguard the internal wax thermo-element against debris and limescale.
- Factory Precision: Genuine Grohe OEM component engineered to exact tolerances, ensuring smooth temperature control and reliable shut-off.
Installation Note
Always isolate hot and cold water supplies before servicing. Note that 47186000 is a 3/4" compact cartridge (the reversed equivalent of standard 3/4" cartridge 47282000 / 47310000). It must not be confused with the smaller 1/2" reversed cartridge (part 47175000). Ensure the inner brass valve cavity is flushed clean of debris, lightly lubricate the replacement rubber O-rings with WRAS-approved silicone grease before insertion, and recalibrate the 38°C safety stop using a digital thermometer upon reassembly.
