Dosing depends on system size, construction materials, and fluid condition. For this reason, we recommend a system fluid sample is taken and analysed prior to any remedial work. Hydratech offers comprehensive testing and analysis services, for more information visit - Testing & Analysis

Recommended standard dosing
Dose Sureflow COR6 at 4 litres per 2000 litres of system volume, or 0.2% v/v of the total system volume.

We suggest sampling and analysing system fluids biannually to catch any issues early.
