Because of the product’s limited service life and to
prevent costly repairs or possible water damage, we strongly recommend that the bottom of all plastic housings be replaced
every ten years. If the bottom of your housing has been in use for longer than this period, it should be replaced immediately.
Date the bottom of any new or replacement housing to indicate the next recommended replacement date.
