Magnesium Anode Rod. Suits many HWS. Caravans Plus also sell a genuine Suburban anode rod that is recommended by the importer for use with the Suburban HWS.
While we sell a lot of these because the price is very competitive and many of our competitors sell this brand they are not recommended by Coast to Coast who import the Suburban HWS. This is due to the thread being BSP instead of NPT, which has a different pitch.
We have been selling this product for several years now. These are popular with our customers and we sell a number per week. We try to keep plenty on our shelves for quick delivery. If you order more than the 14 we have in stock, the delay is around 5 days to get more.
