Float Switch

Are the 890 series cable weights for the float switches suitable for potable water?

Are the 890 series cable weights for the float switches suitable for potable water?

We carry two types of cable weights, a cast iron and a plastic type.

The 890-AW-CI cast iron cable weight is zinc plated for corrosion resistance; this plating has not been tested for any health effects related to potable water. Therefore, it should not be used in a potable water application.

The 890-AW plastic cable weight is not currently NSF-61 certified for potable water applications, however the materials from which it is molded are generally regarded as safe and are used to manufacturer other NSF-61 certified products. Therefore, they have been widely accepted, considered “suitable”, and are being used in potable water applications.

WARNING: The decision regarding using a non-certified product and their suitability is fully the responsibility of the installer or end user. The 890-AW must not be used in any application where the job specification or applicable plumbing and building codes require NSF-61 potable water certification.

Finally, there is an NSF-61 certified cable weight solution!

We do not stock this item! It can be purchased as a special-order item. The NSF-61 certification was obtained as a kit including both the weight and float switch. Unfortunately, the NSF-61 certification does not apply to the cable weight as a separate item, therefore we cannot offer the weight on its own. If NSF-61 is required for your application, please contact your Boshart sales representative.
