[pianotech] DamppChaser problem

[David and Jean Weiss]

I had the same issue once.  It turned out that the water system in
customer's  house used some kind of salt based filter.  The white stuff
building up on the Dampp Chaser pads is if a residue of the salt.  (Sorry if
my explanation is not very scientific.) 

 

It doesn't seem to interfere with the operation of the Dampp Chaser.  If it
bothers them they could switch to distilled water.

Hi List,

 

I have a strange problem with a Dampp Chaser I've installed about one year
ago.

The system is perfectly maintained (water from a filtering system, the Dampp
Chaser product has always been added, new piano, new building with floor
heat.)

 

Last week I 've checked  the system and was amazed to see big white
mushrooms growing above the humidifier pads!

 

I asked the supplier what could be the problem and he said it's the first
time he encountered this.

 

Any ideas how to avoid this?

 

Thanks,

 

P Gevaert
