Holdly HGY17 Electronic Water Descaler

What it does for your water

The Holdly HGY17 Electronic Water Descaler is an electronic descaler that works on the pipe from the outside.

Like every salt-free option, it leaves the hardness minerals in the water: a test strip reads the same afterwards, and the maker's claim is about scale, not softness.

Electronic units need a power outlet near the pipe and work only on the pipe they are wrapped around; the maker lists which pipe materials and diameters suit them.

The listing also gives features listed Scale Prevention; mounting Under Sink; power No Power Source; capacity stated as 1.5 in; model HGY17; material Polypropylene, Strontium Ferrite.

The listing gives nylon bolts, wing nuts in the box.
