waterloo biofilter alarm going off
New to this forum and I have a question. My alarm on my system went off last night I silenced it and looked in my manual, it says that my water levels are high and I should call my mainatance provider. Now we have lived at the house for 7 years now and the system was put in 5 years prior to that. I can only assume that my tanks need to be pumped or should I call the contractor that installed it and pay him to tell me to have them emptied? Any input would be great!
Thanks in advance,
