I purchased three of your Corro-protect units and so far I am quite pleased! The first one I installed in my house, I am on city water, and had to change my anode every 10-12 months. As my hot water heater uses a hot side nipple style anode, it was always more pricey than a conventional one. I’m hoping it ends up saving me money over time.
The second one I installed in my Mom’s home. Small town water, and again as she lives 1-1/2hrs away from me, it’s a convenient solution to reduce maintenance at her place as she is in her mid 80’s and lives alone. Again it’s a hot water side anode so will hoping it saves me some money and one less thing on the “to-do list”.
The third one went to my brothers house. Well water with the typical “smell”. As his kids grew up and moved away, there was less water usage and the water smell become worse. Happy to say within less than a day, the water smell was completely gone! This was a conventional style anode.
All were easy to install, and no issues to date!
