The products offered here are designed to make water heaters last longer, or solve specific problems. Installation is potentially do-it-yourself, but if you have the least doubt about your abilities, we suggest that you obtain expert help.

Remember also that if you have difficulties with installation, odds are that a professional or handyman will know a way to do it.

Shipping is by UPS within the contiguous United States. UPS does not deliver to post boxes. Allow up to about a week for delivery. Canada, Hawaii and Alaska are only served by Priority Mail and can use a post box.


Are you ordering the right anode? This anode requires its own port in the water heater and is usually a replacement. Make sure you have a hex-head rod in your tank and not a combo (outlet) anode.
