- GROHE Water Saving technology reduces water consumption by up to 50% without compromising on performance; Whenever you turn on your tap, you will enjoy a full jet of water while saving money nonetheless
- Just wipe down with a dry cloth – the smooth surface finish is hard-wearing and ensures a lasting luminous sheen; You'll save plenty of time cleaning while your tap always looks new
- Fit your taps hassle-free using our easy installation system; Taps are connected to the mains by flexible hoses – much simpler to get a grip on – and our step-by-step guides take all the stress out of the job; Even a professional fitter will thank you for choosing Easy Installation
- Before You Buy: This tap has a G3/8" European connection; UK homes often use G1/2" fittings, so please check your connection size; If you have G1/2", you will need a pair of 15mm compression x 3/8" BSP male adaptors (sold separately)

## Questions & Answers

**Q: Can this tap withstand hard water?**
A: Yes we have had it in for two years now and live in a hard water area. Had no issues at all.

**Q: Hi there where do you buy the remote from to re program the sensor position please ?**
A: The remote is about £300 so unless you’re a professional bathroom fitter you won’t be buying that. You can’t change any of the settings without the remote.

**Q: Is there a brass version of this, also mains powered?**
A: I believe there is. However....since having the tap for 15 months. I have the battery operated one, had two battery replacements...a new tap replaced by Grohe in July 2022. Not surprised, battery dead once again.

**Q: Confirm mains-powered is an UK Plug?**
A: I’ve had mine for about 15 months and the battery has already gone flat. It’s in an upstairs bathroom just shared by my husband and I.

Bought the 2 and they both stopped working terrible product

### ⭐⭐⭐⭐⭐ Very Disappointed
*by I***N on 16 November 2022*

The battery came for about 11 months and since then i have changed 4 batteries in the past one month. I ordered grohe battery from amazon paying about £32 still runs for a week or two and stops. I am left with no option but to change the tap now. Not to forget all the running around and wait times before i can get a plumber to do the job!! My bathroom is without a tap now!
