Boiler Low Water Alarm in Randpark
The low water cut-out trips and stops the boiler even when the tank has water. This page covers how we diagnose and repair it on steam systems in Randpark.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Randpark sits within the Randburg belt, with larger stands, long hot water runs and frequent pool heating. Static pressure and dead-leg length are checked as part of any hot water complaint here. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.
