I called Water Rite this morning to check on the product, quantities, and recent pricing. The gentleman that answered the phone advised they have no stock or inventory presently and are in search of a supplier. He advised that I send an email requesting that same information & they will respond when/if they do have product. I sent an email to the address provided in the link. 

That's all I know for now. Slightly disappointing.

Massey 1155, wondering when you last purchased Water Rite?

Thanks
