Toilet Keeps Running/Won’t Flush: If this is the case, the toilet chain may need readjusting, or a new float ball or fill valve is needed. Float balls and fill valves are cheap and can be found at any hardware store. In this scenario, you can fix your toilet on your own, however, if you feel uncomfortable a professional would be happy to look into it for you.
Tank Takes too Long to Fill: If you notice your toilet is taking a long time to fill there may be a problem with the shut off valve and this particular part may need replacing.
Toilet Tank Leaking: If you start to notice pooling of water around the base of your toilet there may be loose bolts or a problem with the feed line. Call a professional as soon as you notice any water like this to prevent any serious damage.
Clogs Frequently: If you find yourself plunging more than once a week and it is becoming an annoyance, it may be time to consider replacing. Older low flush toilets also often require a few more flushes and if you have an older toilet it might be time to consider upgrading.
Porcelain Crack: Hairline cracks on the tank or bowl can cause a flood. These cracks can also signal an active leak. It is important to keep an eye out for these cracks to prevent any leaks or larger cracks. If you do notice a hairline crack call a professional to check it out and look into getting a new toilet.
Visual Scratches: It becomes increasingly difficult to clean a toilet when there are visual scratches. To decrease frustrating and a dirty toilet it may be time for a replacement.
Save Water/ Money: If you haven’t yet gotten a low-flush toilet it may be time to invest to save money in the long run. Low-flush toilets use about 2 gallons of water compared to 3-5 gallons.
Again, a good rule of thumb when considering replacing or repairing is if the cost of repairs is more than 50% of the cost of a new unit, a new unit may be the most cost effective.
