On a regular periodic basis, we deliver salt and chemicals to our water softener customers. We charge only for the salt and chemicals; we deliver it for free. We also provide a complete equipment inspection while we are on your site. Our goal is to eliminate all service calls. If you have an equipment related service problem between the times we service your unit, we do not charge for equipment related service calls on our rental equipment, and we strive to be there within 24 hours of receiving the call.
