John -- Don't think they will spring for the cover, but perhaps the humidifier part of the system is overkill in this situation. I think your suggestion of just disconnecting the humidifier and leaving the de-humidifier might be the best choice. Don't need to add moisture where there is already too much. -- Geoff Sykes Assoc.

The dryest my house has ever gotten was 65% R.H. (Once monitered and recorded 24/7 for an entire year for an unrelated film industry project, however I found the info quite relavent to our profession). This, and stories from other L.A. technicians that they have removed more humidifiers than they've installed. Do you really need the humidifier? We don't have the bone chilling winters that cause us to turn on the heat and dry out the house. In my community the strings rust prematurely from the high relative humidity, and salt content from the ocean...my first recommendation to all new piano owners is an Edwards String Cover...even more so than D.C.

Briefcase ] Greetings all -- About a year ago I replaced an old rusted out DC system in a clients grand with a complete new system and control box. The water tank support rails had literally rusted away and the tank had fallen out. Did I say it was old? Anyway, at the same time I also replaced two broken strings up in the high treble. The entire piano was on the rusty side and my guess is that age along with rust had caused these two strings to break. On a return visit last weekend I found another string up in the high treble had broken. I also noticed increased signs of rust, most notably on the new strings I had replaced only a year ago. The client lives in Los Angeles about three miles from the beach. She tends to be cold most of the time so the forced air heating system runs a lot. While the vent in the piano room is blocked, there is a sliding glass door that is infrequently open leading to the outside. All in all not what I would call an environment that would be rust promoting. Could the DC system be causing the rust? I'm open to suggestions. -- Geoff Sykes Associate Member Los Angeles Chapter _______________________________________________ pianotech list info: https://www.moypiano.com/resources/#archives -- No virus found in this incoming message.
