The TOP 3 Features that truly define the quality of a Water Dispenser


What do you first look out for when buying a water dispenser? Is it the appearance of the system? Multiple Functionalities? Where it is made from?

Unknown to most, much of the actual important features are on the inside of the system.


No. 1: Tank Storage – Dispensing Method

The ‘Gravity Tank’ method:

Most conventional water dispensers use the ‘float valve’ to top up and dispense water. This is similar to that of the toilet cistern that we are all familiar with – when you flush (dispense), the water flows down based on the existing weight of the volume of water, causing the float to drop and trigger incoming water to top up the tank.

This method can produce a nice flow rate of dispensing even if the incoming water pressure is extremely low. However, the flaw with using this method for drinking water is the air pocket right above the maximum water level. This uncirculated air gap promotes growth (bacteria & Algae) and the water often have cold spots where the ‘older’ water never gets dispensed out and stays in the tank.


There are instances where insects such as ants make their nests in these permanent air gaps.

The ‘Sealed Tank’ method:

The water tank is completely sealed and depends on incoming water pressure to dispense water.  Although dispensing rate depend on your home water pressure levels, it is much more hygienic and safer for immediate consumption use.

No. 2: Tank Storage – Material

Plastic Tank Storage:

Plastic tanks are known to be more conducive for bacteria and algae latching and growing on its surfaces. (especially more so if they are also the ‘float valve’ type).

A plastic water tank storage using a ‘float valve’ system:

Such tanks require frequent cleaning and sanitizing to keep the water hygienic and safe for immediate consumption.

Stainless Steel Tank Storage:

Stainless Steel (304 and above quality) are much better at prohibiting organic growth and is highly recommended especially if it is a heated tank. Stainless steel tanks tend to be more durable less prone to leaking due to degradation over time.

A Sealed Water Tank:


No. 3: Safety Features

Back-up Thermostat:

Ever wonder what could happen if your hot water heater does not know when to stop heating?

A ‘burnt’ dispenser suspected to be triggered due to lack of safeguards:

Usually a thermostatic sensor within the hot water tank stops the heating when the desired temperature is reached. A quality system should always have a backup sensor as a safeguard to prevent overheating.

Swisspro prioritizes these functionalities and our CLIMA series (MESA, PISO, UNICO, VERSA) come equipped with 304 Stainless Steel SEALED TANKs that assure the highest level of hygiene safety.  They are also packed with safety features to ensure reliability and peace of mind.
