Like many things in nature we all need a certain amount of water, Your piano is no different. However having too much or not enough can both have damaging effects. Not enough water and your soundboard may crack, wood pieces can dry up and separate at the joints. This also has a direct effect on your pianos tuning, causing most pianos to go flat. Too much water and your pianos wooden parts tend to swell and the next thing you know your keys become sluggish or they stick. Of course your tuning will go off because your soundboard will swell and put more pressure on the bridges which in turn puts pressure on the strings. Most Pianos are made to exist at 42% relative humidity. However because of seasonal changes and home heating and air conditioning, this is rarely the case. In fact the worst thing is that your piano fluctuates in it's relative humidity and this up and down swinging of humidity causes most piano problems. Church and school pianos suffer the most as these buildings are at one time fully occupied with people, raising the humidity. Then the buildings are empty, lowering the humidity. The best cure? The installation of a Dampp-Chaser  piano life-saver  system. This system will maintain your piano's relative humidity levels at 42% plus or minus 5%.
