I’m having a problem with the toilet flushing completely. It’s been like that since we bought the property. All the components in the tank are in working order. The water does not seep into the bowl after the flush. The water level is adequate. The drain is not clogged. Tested it by pouring a bucket of water into the bowl without difficulty. I noticed something out of place; the tank looks older than the bowl. On the top of the bowl, behind the toilet seat, it says American Standard – Water Saver. I checked the date under the lid of the tank. It stated June 1975. I know the water saver toilets didn’t come into the market until the 1990’s. Is it possible the tank is not compatible with the bowl? Your feedback would be appreciated. Thanks.
