Depends how you drive.
I don't think you are getting it. The DOS head-caps and their peri-tube (like all peristaltic pumps) are a consumable product. Not unlike brake pads or even inkjet cartridges. Depending on how much you use it determines how fast it will need replacing.
Ultimately this is not the place to hash this out. If you want to have this kind of discussion, I encourage you to engage other DOS users over on our forum dedicated to the DOS here: https://forum.neptunesystems.com/fo...-amp-DDR-%96-Dosing-and-Fluid-Metering-System
Thanks for the compliment on the tank!
You are the man when it comes to all this stuff..i have designed my tank from reading and studying this thread!
I trust all you say and promote...but ...we want a dosing system we don't need to worry about.
Admit it may be a bit silly to have to replace heads at 750 hours and we are good!
