water over time and the air pressure has to be periodically replenished. Adding compressed air at a schrader-type valve (like on a car tire) located at the top of the tank fixes the problem in most cases.

   Newer type tanks have a flexible bladder inside the tank separating the water from the air, so they do not gradually lose air. They also have an air fill valve; and most have the water in the bladder and the air in the surrounding space in the tank, but some manufacturers have the two reversed. When the bladder eventually deteriorates and ruptures it can cause a number of problems, one of which is short cycling. In some cases the bladder can be replaced, but it usually recommended to replace the entire tank—especially with an older tank that has corrosion.


While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
