Too much aspiration cleaner
You would think adding a little bit more Puli-Jet cleaner would help to keep your system clean. This is not the case as it does more harm than good. Also not using the cleaner the correct way, using cold water when you should be using hot water. We visit so many dental practices with problems caused by not using cleaning products the right way. You would not believe the damage it does to your suction pumps.
Suction pumps, motors, pipework, amalgam separators and filters get destroyed over long periods of misuse.
