About this part

Primochill Sys Prep was created to address the immense customer requests for a clean and well maintained cooling system. Any successful venture into water-cooling starts with a true cooling loop preparation which can only be achieved by using Sys Prep. It will “flush” your loop and its components of any debris left by the manufacturing processes of your reservoir, block, pump, or radiator, leaving your water cooling loop clean, clear, pristine and ready for any type of coolant. Let Primochill Sys Prep take the confusion out of what is causing the filth and let it “flush” and “prep” your next cooling loop. Over the last decade, PrimoChill has strived to provide the water-cooing community quality products that inspire our customers. Get clean and protect your investment with PrimoChill Sys Prep.

Great Prep Solution!

12 hours in and its a clean system! Im not real knowledgable of chem treatment but this gave me the confidence it was clean and ready to go.

Fantastic.

I used to use different methods to clean and flush my loop with varying results. But then I started using the Primochill SysPrep and have never looked back. It does exactly what it says it does. Flushes out debris, cleans away buildup, removes everything that would affect the PH and efficiency of the coolant, etc. Keeps coolant from breaking down.

Before you install it

This is a component, not an assembly — how it goes in depends on the loop it is joining. What does not change is the last step: leak test before power. Run the pump on a bench supply with the rest of the system unpowered. 24 hours is the standard, an hour is the minimum.

Custom water cooling is installed by you, at your own risk. We are not responsible for leaks, or for damage to your parts or system. If you're unsure at any step, ask before you power the loop.
