Replacement Procedure: How to Fit the Franke Wave Spare Cartridge

Cartridges will deteriorate due to the presence of hard water, excessive water pressure, or the normal wear and tear. As a safety precaution, turn off both water supply lines before beginning the replacement.

• Accessing the cartridge implies removing the tap’s left side handle by loosening the grub screw located underneath. Next, undo the screw of the insert sitting on top of the cartridge. Then, release the cartridge using a spanner.
• Flush the valve with water to remove dirt.
• Layer silicone grease on the O-ring of the new Franke Wave tap spare and install it in the tap unit. Reassemble the valve handle.

Tap Facts: How Hard Water Affects Taps and Cartridges

Since soft water passes through slate or granite, it contains a much lesser amount of minerals and impurities. Hard water flows through limestone or chalk, taking with it minerals, chlorides, bicarbonates, and sulfates. As a consequence, limescale deposits build up inside and around the tap valve. The accumulation of scale, along with dirt, can block the path where water flows which includes supply pipes, tap spout, and cartridge.

In Britain, over 50 percent of homes are affected by hard water. Cities known to have high levels of hard water are Brighton, Bristol, Lincoln, London, and Southampton. (Please refer to our Water Hardness Map to see different hard water areas in the UK.)

Calcification build-up means there is a need for a new Franke Wave spares replacement cartridge.
