How to Replace
Step 1: Hold down the sides of the Dos Head and the clips will release. Remove the pump head and set it aside.
Step 2: Pick up your new pump head and slip it right down into the old heads position and the clips should click into place. Test the Pumps rotation with the manual priming buttons.

I just noticed my right pump was way under in dosing my NSW amount, due to an alarm on my conductivity.
Looking at the old pump head I noticed a broken support find in the top of the casing, it was flexing too much and changed things. I opened my spare pump head and noticed much more support fins in the new casing, and I'm glad they knew of this and improved on it. Neptune is a Great company.
