I haven't had good luck with installing complete Damp Chaser Units in schools. It seems they get neglected, especially when they really need the attention. Dry water buckets cause cracks in soundboards and bridges fast. If I were there full time I'm sure that would be different. The best I can do for schools is install the dehumidifiers, they don't require the maintenance and just stay plugged in all the time. It does work wonders even though I still have to fight the dry air in the winter. I've found less stress on the piano by controlling the high humidity. I have 5 old Steinway uprights built between 1904 and 1916 at USD. They all just have the dehumidier and sensors. They never go above A440 and very rarely drop more than 5 cents. I wish I could say the same for Baldwin 243's in practice rooms Churches are another matter, as most of them seem quite diligent about filling with water when the light comes on. They especially like less maintenance cost because there are fewer tunings & repairs. I have nothing but praise for the Damp Chaser products when maintained. But keeping them maintained is the key.
