Cornat Basin Shower Kit Instruction Manual
Model: SA141 | Brand: Werkzeyt
1. Introduction
The Cornat Basin Shower Kit, Model SA141, is designed to provide a convenient and versatile showering solution by converting a standard basin tap into a functional shower. This retrofit shower head allows for easy switching between tap and shower functions with a simple hand pressure button. It is compatible with all standard fittings featuring an M22x1 or M24x1 aerator and is suitable for use with continuous flow water heaters.
2. Safety Information
Please read all instructions carefully before installation and use. Failure to follow these instructions may result in property damage or injury.
- Ensure water supply is turned off before beginning installation or maintenance.
- Do not use abrasive cleaners or materials that could damage the chrome finish.
- Verify compatibility with your existing faucet's aerator thread size (M22x1 or M24x1) before installation.
- If you are unsure about any installation steps, consult a qualified plumber.
3. Package Contents
Your Cornat Basin Shower Kit package should contain the following:
- 1 x Cornat Basin Shower Kit (Retrofit Shower Head with Hose and Connector)

4. Setup and Installation
Follow these steps to install your Cornat Basin Shower Kit:
- Turn off Water Supply: Locate the main water shut-off valve for your basin faucet and turn it off. This prevents water flow during installation.
- Remove Existing Aerator: Unscrew the aerator from your basin faucet. Most aerators can be unscrewed by hand or with a wrench if necessary.
- Check Compatibility: Ensure your faucet's thread is either M22x1 (male thread) or M24x1 (female thread). The Cornat kit is designed to connect directly to these standard sizes.
- Attach Shower Kit Connector: Screw the connector end of the Cornat Basin Shower Kit onto your faucet's aerator thread. Hand-tighten first, then use a wrench if needed, but do not overtighten to avoid damaging threads or gaskets.
- Turn on Water Supply: Slowly turn the main water supply back on and check for any leaks at the connection point. If leaks occur, tighten the connection slightly.

5. Operating Instructions
Using your Cornat Basin Shower Kit is straightforward:
- Faucet Mode: When the pressure button on the shower head is not pressed, water will flow normally from your basin faucet.
- Shower Mode: To activate the shower function, simply press and hold the black pressure button located on the side of the shower head. Water will then divert from the faucet to the shower head.
- Switching Back: Release the pressure button to return water flow to the basin faucet.
- Water Temperature and Flow: Adjust water temperature and flow using your basin faucet's controls as usual.

6. Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your Cornat Basin Shower Kit.
- Cleaning the Finish: Clean the chrome surfaces with a soft cloth and mild soap or a non-abrasive bathroom cleaner. Rinse thoroughly with water and dry to prevent water spots.
- Cleaning Nozzles: If water flow becomes uneven or reduced, mineral deposits may be clogging the shower head nozzles. Gently rub the silicone nozzles to dislodge deposits, or carefully remove the spray cap (as shown in Figure 5.2) and soak it in a vinegar solution to dissolve stubborn buildup. Rinse well before reattaching.
- Hose Inspection: Periodically inspect the flexible hose for any signs of wear, kinks, or damage. Replace if necessary.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leaks at the connection point. | Loose connection or damaged washer. | Ensure the connection is hand-tight, then use a wrench for a quarter turn if needed. Check if the rubber washer is properly seated or replace it if damaged. |
| Low water pressure from shower head. | Clogged shower head nozzles or low water pressure from faucet. | Clean the shower head nozzles as described in the Maintenance section. Check your basin faucet's water pressure. |
| Water does not switch between faucet and shower. | Button mechanism issue or internal blockage. | Ensure the button is fully depressed. If the issue persists, the internal mechanism may be faulty, and replacement might be necessary. |
