  • Cons: Relies on staff remembering to perform manual regeneration, which can be forgotten.

Case Study: Real Business, Real Results

The Crooked Chimney pub in York, located in a notoriously hard water area, was struggling with constantly cloudy glassware and  their Classeq G500 glasswasher needing frequent, costly descaling services. They decided to install the Classeq WS16-SK to tackle the root cause.

"We were fighting a losing battle with limescale. Glasses looked grubby, and  the machine was always struggling. Since fitting the softener, the difference is night and  day. Everything is gleaming, and  we haven't had a single scale-related issue since."

Robert Green – Landlord

The pub has now eliminated mid-contract engineer call-outs for descaling, saving an estimated £400 per year in maintenance fees.

Installation and  Maintenance Guide

Setting It Up

  • Position the softener on a flat, level surface close to the warewasher.
  • Ensure it's connected to the cold water mains supply *before* the water enters your dishwasher.
  • Use the provided hoses for a secure, leak-free connection to the inlet and  outlet.
  • Before first use, perform an initial regeneration cycle as per the manual to charge the resin.

Keeping It Going

  • Regularly check the salt level and  top up with granulated dishwasher salt as needed. Don't let it run empty!
  • Perform a manual regeneration cycle periodically. The frequency depends on your water hardness and  usage levels.
  • Wipe down the stainless steel exterior with a damp cloth to keep it clean.
  • Briefly check the connecting hoses for any signs of wear or leaks during your weekly kitchen checks.

Buying Guide: Choosing the Right Commercial Water Softener

Not sure what fits best for your setup? Here are a few things to consider before you buy.

Check Your Water Hardness

Use a simple water testing kit or check your local water authority's website. This will determine if you need a softener and  how often you'll need to regenerate it.

Match Capacity to Usage

A 16-litre unit is great for medium-use sites. Very high-volume kitchens might need a larger capacity to avoid regenerating too frequently during service.

Manual vs. Automatic

This is a manual unit, which is cost-effective and  reliable. Automatic softeners handle regeneration themselves but are more expensive and  complex.

Consider Your Space

Check the dimensions (620x180mm) to ensure you have enough space next to your warewasher for installation and  easy access for adding salt.

Temperature Matters

This unit is designed for a cold water feed (up to 35°C). Ensure your plumbing setup is compatible, as hot water can damage the internal resin.

Compatibility is Key

This model is designed specifically for certain Classeq machines. Always double-check your warewasher's model number to ensure a perfect match.

Frequently Asked Questions

Q: How often will I need to add salt?

A: This depends entirely on your water hardness and  how much water you use. In very hard water areas with high usage, it could be weekly. In other areas, it might be every few weeks.

Q: What is 'regeneration'?

A: Regeneration is the process of flushing the collected hard minerals from the resin beads and  recharging them with sodium from the salt, ready to soften more water. This is a manual process for this unit.

Q: Does the Classeq WS16-SK water softener need an electricity supply?

A: No, it is a completely non-electric unit, which simplifies installation and  means there are no running costs or electronic parts to fail.

Q: What kind of salt should I use?

A: It is designed to be used with granulated dishwasher salt, which is widely available and  cost-effective.

Q: How do I know if I need a commercial water softener for my dishwasher?

A: If you see white, chalky deposits (limescale) on your equipment or glassware, or if your local water board states your area has hard water (over 100 ppm or 7° Clark), a softener is highly recommended.

Q: Can this be used with a hot water feed?

A: No, this unit is designed for a cold water fill only, with a maximum temperature of 35°C.

Q: Is this difficult to install?

A: Installation is straightforward for a qualified plumber or catering engineer, involving connecting the water inlet and  outlet hoses between the mains supply and  the warewasher.

Q: Will it reduce my water pressure?

A: When installed correctly, the unit is designed to have a minimal impact on water pressure and  flow, with a maximum delivery of 800 litres per hour.

How Base Exchange Softening Protects Your Pocket

Ever wondered how a base exchange water softener 16 litre actually works? It’s clever, but surprisingly simple. Think of it like a magnet for limescale. Inside the softener are thousands of tiny resin beads, all holding onto soft sodium ions (from the salt you add). When hard water flows past, the 'hard' minerals like calcium and  magnesium—the culprits behind limescale—are more attractive to the resin. So, the resin grabs the hard minerals and  releases the soft sodium ions in their place. This 'exchange' stops limescale dead in its tracks, long before it has a chance to coat your machine's heating elements and  pipes. It's a simple swap that saves you a fortune in repairs and  descaling chemicals.
