Installing a boiling water tap can make everyday kitchen tasks more convenient by providing near-boiling water directly from the tap. If you are replacing an existing kitchen tap or upgrading your sink area, knowing how the installation works can help you prepare.
A boiling water tap installation involves fitting the tap, positioning a compact boiler tank beneath the sink, connecting the water supply and checking that everything is working safely. Whether you choose a 3-in-1 or 4-in-1 boiling water tap from Verossi, the installation follows a similar process.
What Do You Need Before Installing a Boiling Water Tap?
Before you start, make sure you have enough space and the right connections for the new tap. The main requirements include:
- Tools and installation fittings: Gather an adjustable spanner, screwdriver, tape measure, suitable connectors and the washers, seals and fixings supplied with your tap.
- Available space beneath the kitchen sink: Make sure there is enough room for the boiler tank and water filter, with adequate ventilation and access for future maintenance.
- Water supply and pressure requirements: Make sure your existing water supply meets the tap’s requirements. Verossi specifies an operating water pressure range of 1 to 3 bar for its boiling water taps.
- Electrical socket requirements: Check for a suitable, safely positioned and accessible earthed socket beneath the sink, away from potential water exposure. Verossi boiling water systems use a standard fused plug, so the boiler does not normally require hardwiring.
- Tap hole size and compatibility: Check whether your existing sink or worktop has a suitable opening. Verossi specifies a standard 35 mm mounting hole for its boiling water taps. Also check the worktop thickness and any model-specific clearance requirements.
- Manufacturer's installation instructions: Review the installation manual to confirm the correct fittings, connection sequence and safety requirements for your model.
Step-by-Step Guide to Installing a Boiling Water Tap
The following steps provide a general overview of the instant boiling water tap installation process. Always follow the instructions supplied with your particular model, as connections and components may vary.
Step 1: Turn Off the Water Supply and Remove the Existing Tap
Start by shutting off the hot and cold water supplies using the isolation valves beneath the sink. Open the existing tap to release any remaining pressure.
Place a towel or container underneath the connections to catch residual water. Disconnect the supply hoses, loosen the retaining fittings and carefully remove the old tap.
Clean the mounting area before proceeding.
Step 2: Fit and Secure the New Boiling Water Tap
Insert the new tap through the existing hole in your sink or worktop, using the supplied sealing components.
Secure it from underneath with the appropriate washer and fixing nut. Check that the tap is correctly aligned and stable before tightening the fittings.
Guide the connecting hoses beneath the sink, ensuring they are not twisted, stretched or sharply bent.
Step 3: Position the Boiler Tank and Water Filter
Position the boiler tank upright on a flat, stable surface beneath the sink. Leave sufficient clearance around it for ventilation and future servicing.
Position the supplied water filter where it can be accessed for replacement. Check its required orientation and ensure the connecting hoses can reach their fittings without excessive tension.
Avoid placing items against the boiler that could obstruct ventilation.
Step 4: Connect the Water Supply and Boiler System
Connect the tap's standard hot and cold water hoses to the appropriate supplies.
Next, connect the cold water feed, filtration system, boiler inlet and boiling water outlet according to the manufacturer's connection diagram. Use the supplied fittings and keep any isolation valves easy to reach.
Make sure all the connections are secure and the hoses are positioned correctly.
Step 5: Fill the System, Check for Leaks and Test the Tap
Slowly turn the water supply back on and inspect the connections for leaks.
Following the manufacturer's priming instructions, operate the boiling water function until water flows steadily from the tap, confirming that the boiler has filled before connecting it to the electrical supply. Running an empty boiler can damage its heating components.
Once the system is filled and leak-free, switch on the boiler, select the desired temperature using the boiler controls and allow the water to heat.
Finally, test the tap's functions, including its boiling water safety mechanism, to confirm everything operates correctly. Check the connections again for leaks after the system has heated.
Should You Install a Boiling Water Tap Yourself or Hire a Professional?
Verossi boiling water taps are designed for easy DIY installation, so professional assistance is not always necessary. Both the 3-in-1 and 4-in-1 boiling water taps are supplied with the necessary fixtures and fittings, along with clearly labelled components to simplify installation. Installation can take less than 13 minutes under suitable conditions.
If your kitchen already has suitable plumbing connections, an accessible electrical socket and sufficient under-sink space, you may be able to install the tap yourself by following the supplied instructions. If your kitchen requires plumbing alterations, a new electrical socket or worktop modifications, professional assistance may be necessary.
