Magnetite — iron oxide from ongoing corrosion. The most common single indicator.
When a loop is corroding, fouling, or losing capacity, cleaning it isn't enough — something is causing it. PurgePro diagnoses the root cause, restores the system chemically and mechanically, and documents the water chemistry that proves it's fixed.
Hydronic system remediation is the process of diagnosing and correcting a closed-loop system that has become corroded, fouled, or chemically unstable. Unlike a flush, which mechanically removes loose debris, remediation identifies the underlying cause of the failure — oxygen ingress, failed water treatment, microbial growth, or glycol breakdown — then chemically cleans the bonded deposits, passivates the exposed metal, restores corrosion inhibitor, and verifies the result through water testing.
The most common cause. Undersized or waterlogged expansion tanks, air vents pulling in rather than pushing out, negative pressure at the pump suction, or oxygen-permeable barrier tubing. Fix the chemistry without fixing the ingress and it comes straight back.
Inhibitor consumed and never replenished, or dosed at the wrong concentration. Partially depleted inhibitor can be worse than none — it can concentrate attack rather than prevent it.
Bacterial colonies, including sulfate-reducing bacteria, forming biofilm and pitting the metal beneath it. Often the cause when a loop fails despite apparently correct chemistry.
Glycol breaks down over time into organic acids, dropping pH and stripping inhibitor. A loop that hasn't had glycol tested in years is a common find.
Steel, copper, and aluminum in one loop without appropriate multi-metal inhibitor chemistry.
Once sludge settles, the metal beneath it corrodes in an oxygen-starved cell that treatment chemistry can't reach. This is why deposit removal has to come before re-inhibiting.
