Mandatory To Maintain Warranty

The title says it all. If you want to maintain the warranty on your Weil-McLain boiler, you must use this product to protect the boiler's internal workings. It will also help protect your circulating pumps and low water cut-off switch. It has gotten expensive (double the price in less that 3 years), but it is a lot less expensive than replacing any of the boiler's parts.

Have no idea if this product does anything, it's supposed to prevent corrosion. Weil-McLain requires an anti-corrosion additive to keep warranty in good standing, so I guess in that capacity this product fills the bill nicely! Does include an application tube for easier injection into piping. It's expensive, hard to find (in the US) Our eComfort transaction and shipping experience was tip top.
