For the Villagers who are having cannister issues with their Nova filter, have you checked to make sure, if you have a tank hot water heater that the expansion tank is not defective? These only last about 5 years then need to be replaced. If your expansion tank is defective, that could also cause excessive pressure in your water system and potentially cause the Nova Filter or any filter cannister for that matter to fail.
All you need to do is tap on the top and bottom of the expansion tank with a metal screwdriver and if the sound is the same thud then the tank needs replacing.
