Expert Review and  Insights

When you're fitting out a commercial washroom, the components you can't see are often the most important. The KWC DVS kit is a solid, no-nonsense choice. Its WRAS approval is non-negotiable for commercial premises, and  the build quality is exactly what you need for a fit-and-forget solution that won't cause headaches down the line.

  • Pros: The WRAS approval is a huge plus, ensuring full compliance from day one.
  • Cons: Installation requires a stud wall, so it's not a direct swap for close-coupled toilets.

Case Study: Real Business, Real Results

The team at 'The Northern Cask', a popular craft beer pub in Sheffield, decided to completely refurbish their customer washrooms to match their modern, industrial aesthetic. They needed a concealed WC cistern for restaurants that was robust and  space-efficient.

"We wanted a clean look that was tough enough for a busy Saturday night. The KWC DVS cisterns were perfect. They're hidden away, so the toilets look great and  our cleaning team finds them so much easier to maintain. Customers have even commented on how much better the facilities are."

Robert Mills – General Manager

The refurbishment has resulted in a 30% reduction in daily washroom cleaning time and  a significant increase in positive customer feedback regarding facilities.

Installation and  Maintenance Guide

Setting It Up

  • Always ensure your stud wall or partition has sufficient strength to support the cistern and  toilet pan.
  • We recommend having a qualified plumber handle the installation to ensure all connections are secure.
  • Before boxing the unit in, perform several test flushes to check thoroughly for any leaks.
  • Make sure the flush plate or button access panel is correctly aligned for future maintenance.

Keeping It Going

  • Access for maintenance is typically through the flush plate; keep this area clear and  accessible.
  • In hard water areas, consider using an in-cistern cleaner periodically to prevent limescale build-up.
  • Wipe down any external flush plates or buttons with a soft, damp cloth and  mild detergent only.
  • Annually check the fill and  flush valves for smooth operation, which can be done by a maintenance professional.

Buying Guide: Choosing the Right Concealed Cistern

Not sure which hidden cistern is right for your space? Here are a few pointers to help you decide.

Wall Type & Depth

Check the depth of your stud wall. Slimline cisterns like this one are designed for standard cavities, but always measure first to ensure a perfect fit.

Flush Activation

Consider what kind of flush plate or sensor you want. This cistern is designed for use with a DVS flush valve kit, so ensure your chosen activation method is compatible.

Compliance is Key

For any commercial setting, only choose a WRAS Approved cistern. It's a legal requirement that ensures the safety of your water supply and  protects your business.

Pan Compatibility

This kit is designed for back-to-wall or wall-hung toilet pans. Make sure the pan you've chosen is compatible with a concealed cistern setup.

Ease of Maintenance

Look for systems that allow all maintenance to be done through the flush plate opening. This avoids having to remove tiles or panels if a part ever needs replacing.

What WRAS Approval Really Means for Your Business

You'll see 'WRAS Approved' on lots of plumbing gear, but what is it? Think of it as a seal of approval from the UK's water regulators. It certifies that a product, like this KWC DVS concealed cistern, has been rigorously tested to ensure it won't contaminate the mains water supply. For a business, this is absolutely crucial. It's your guarantee that you're meeting legal requirements and  protecting public health. Installing non-compliant fittings can lead to hefty fines or being forced to replace everything. So, that little WRAS logo isn't just a feature; it's your insurance policy for safe, compliant, and  professional plumbing.
