Boiler Low Water Alarm in Morningside
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 Morningside.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Apartment blocks and medical facilities with centralised hot water and recirculation loops. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.

FAQs
Frequently asked questions
What causes boiler low water alarm?
The usual causes are fouled level probe, failed feed pump or check valve, blocked feedwater strainer, air lock in the feed line. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Strip and clean level probes; Feed pump pressure and flow test; Strainer inspection; Level control function test. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
No — isolate the plant and call 069 268 0988. Running it in this condition risks further damage or an unsafe situation.
Do you attend this fault in Morningside?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Ring-main balancing is often the fix rather than replacing plant.
