A pumping system failure usually happens at the most inconvenient moment. In most cases the station works automatically and without intervention, but when a problem arises the consequences can be serious: backflow of wastewater, an unpleasant odour or even flooding.
The good news is that a large share of faults have a logical explanation and can be diagnosed relatively quickly. It is important, however, to react in time.
The pumping station does not switch on
If the system does not start at all, the first step is to check the power supply. Sometimes the cause is elementary: a tripped circuit breaker or an interruption of the supply. In other cases the problem is in the level sensors or the float switch, which register the water level.
If after the basic check the station still does not work, it is likely a defect in the control panel or in the pump unit itself. Technical diagnostics are now required. In such situations ERMAX BG can assist with consultation, inspection of the equipment and, if necessary, replacement of components.
The pump runs but does not pump water
This is one of the most common reasons for a repair call for a pumping station. The pump switches on, but the water level does not drop.
Most often the cause is:
- a blocked inlet or impeller
- a stuck non-return valve
- a build-up of solid waste
Before any intervention the power supply must be switched off. If blockages appear regularly, the station may not be correctly sized for the real load. In such cases ERMAX BG can carry out a technical analysis and propose a more suitable solution for the specific site.
Frequent switching on and off
When the pump starts too often, this leads to accelerated wear. The cause may be incorrectly set levels or an unsuitable pump capacity. This does not always look like a serious problem, but over time it can lead to motor damage.
Proper maintenance of pumping stations includes periodic checking of the settings and an assessment of whether the configuration matches the real load. If the system is operating outside its optimal parameters, it is better to make the correction in time.
Unpleasant odour or build-up of sludge
The odour from the manhole is usually a sign of accumulated sludge or a disrupted biological process. This is typical for sites with seasonal use or low load, where there is no constant flow.
In addition to mechanical cleaning, it is often necessary to restore the biological balance. For this purpose you can use the biological product for cleaning septic tanks, offered by ERMAX BG. It helps break down organic build-up and reduces the risk of odours with regular use.
Noise, vibrations or unusual operation
If the station starts to run noisier than usual or vibrations appear, this may be a signal of mechanical wear or solid particles that have got in. Such symptoms should not be ignored, because they can lead to serious damage.
Timely diagnostics often prevent a more expensive repair of the pumping station and extend the life of the equipment.
Overflow or backflow of water
This is the most critical situation. The cause may be a blocked pipeline, a defective non-return valve or insufficient capacity of the system. In such cases quick intervention and a technical assessment are needed.
ERMAX BG offers solutions tailored to the specific conditions, from replacing an individual element to optimising the entire configuration of the pumping station.
When to seek professional help
It is a good idea to turn to a specialist when:
- the problem recurs regularly
- the system has not been serviced for a long time
- there is a risk of flooding or damage
In many cases a pumping system failure is not the result of sudden damage, but of an accumulated problem or incorrect sizing at the stage of choosing the equipment.
The right approach includes timely diagnostics, regular maintenance and the use of products suitable for the system. When these conditions are met, the pumping station can work reliably for years.
