TOO GOOD TO BE TRUE – Sodium Silicate Dosing into Domestic Hot Water Systems

 

Sodium silicate, sometimes referred to as a “food-grade mineral”, is an inorganic chemical used in many industrial and automotive material applications. It is also used as a low-level corrosion inhibitor at waste water treatment plants.

In other words, it is strong enough to stop rust. Sound like something you’d like in water from your tap?

Before you consider a sodium silicate treatment as a solution to your building’s pinhole leaks, ensure you do your homework and avoid being persuaded by clever sales tactics.

Fortunately, homework is much easier to do, thanks to the Internet and wonderful search engines, such as Google. Before you confirm that sodium silicate doses are a feasible solution to your pinhole leak problem, make sure that you have answers to these questions:

 

  • What is sodium silicate? What has it been used for?

  • How many companies are marketing sodium silicate as a solution for pinhole leaks in residential buildings?

  • Is sodium silicate, an inorganic chemical, being administered properly?

  • Who is going to be testing the water chemistry after the sodium silicate is applied? Do they have legal authorization from Health Canada? (If sodium silicate has already been applied in your building, consider monthly third-party testing to ensure that the dosing levels are safe.)

  • If the sodium silicate is applied at unsafe levels, how will this affect residents’ health? Refer to Material Safety Data Sheets (MSDS) for sodium silicate.

  • If a company specializing in sodium silicate dosing is also doing plumbing work and causes damage, are they legal, insured or bondable?

  • High efficiency components like boilers and heat exchangers can be damaged by exposure to sodium silicate. Will those components be monitored to ensure they are performing correctly? If not, what are the consequences of their poor performance?

 

 

As a solution to pinhole leaks in your domestic hot water system, Rikos’ patented epoxy pipe lining is a 100 per cent safe option with proven effectiveness and durability. While we are confident that it is a superior option to sodium silicate dosing, we don’t expect you to take our word on it…

…but consider this: After more than three decades of industry experience, sodium silicate has never been considered for use in domestic water supplies, even though the chemical has been researched and used in various industrial applications since 1818.

So please, for your residents and your own sake: do your homework. It’s easy.
