A Y-strainer is an in-line filter for hydronic systems. As the strainer starts trapping dirt, resistance to flow (pressure drop) will increase. Measuring the pressure drop across the strainer while the system pumps are running, will indicate how plugged the strainer is.
The Caleffi...
Every hydronic system is different, so there is no absolute correct answer when it comes to how often a dirt separator should be "blown down", however, we can make some general recommendations.

Unless you know the actual system volume, it would be tough to partially fill with demineralized water and then pump in the appropriate amount of glycol. Buying full-strength glycol and mixing it at the jobsite using demineralized water from the Caleffi HYDROFILL...
