Restoring Water Pressure Issues Due to Missing Non-Return Valve in Pressure Booster Pump: A Case Study of Troubleshooting
Client: Private bungalow owner at Veraval, Gujarat
Our client is the owner of a beautiful private bungalow located at Veraval, Gujarat. However, he was struggling with a major problem - the water pressure on the first floor of his bungalow was incredibly low.
The client's friend (who lived nearby) had faced a similar problem of low water pressure. To solve the issue, he had installed our Mega Booster-II, a small (0.5 HP) pressure booster pump, and was delighted with its performance. Impressed with the results, he recommended the same pump to our client.
The client purchased the pump from our authorized dealer and had it installed by a local plumber.
Upon installation, the pump worked properly as it automatically started when they opened a tap. However, when they closed the tap, the pump did not turn off on its own.
Despite the plumber's attempts to resolve the issue, he couldn't identify the root cause of the problem. As a result, our client switched off the pump and reached out to us through our toll-free helpline to register a complaint.
- Customers can register a complaint by calling our toll-free number, after which they receive a text message with information about the complaint as well as the contact details of our service engineer.
- Our Engineer usually calls up to fix an appointment as per the electricity schedule of the area - as there are frequent power disruptions in some places.
Our service engineer reached the site as per the pre-scheduled appointment.
Upon arrival at the location, our service engineer promptly initiated an inspection to confirm the reported issue and determine the underlying cause.
- To diagnose the problem, our engineer conducted a series of standard checks, beginning with examining the power supply.
- Next, our engineer proceeded to check the wiring of the pump, thoroughly examining it for any faults.
- After checking the wiring, our engineer proceeded to investigate any possible leakages in the pipe fittings of the pump apparatus.
- Upon investigation, our engineer determined that there were no issues with the power supply.
- The engineer did not find any faulty connections in the wiring or issues with the installation.
- Following the wiring inspection, our engineer examined the pump's pipe fittings (for possible leakages) and discovered that the NRV (Non-Return Valve) was missing on the suction side, even though it was provided by us with the pump at the time of purchase.
- The Non-Return Valve is one of the most critical components required for the efficient functioning of the Pressure Booster Pump.
- It would be right to assume the negligence of the plumber who forgot to install the NRV.
- Based on these findings, our engineer recommended the installation of the missing NRV to restore proper functioning of our Mega Booster-II pump.
- The client agreed with our engineer and he installed it and when they tried to check the working of the pump, it worked perfectly fine.
- The Mega Booster-II or any other pressure booster pump may also not work efficiently if:
1. There is a problem with the NRV
2. There is problem with the Pressure Switch
3. There are leakages in the pipeline.
4. Bypass line is left open while the pump is in working condition.
- The recommended power supply for a 0.5 HP, Mega Booster-II Pump is 180 to 230 Volts.
- Power fluctuations can cause serious damage to all electrical appliances. Use a stabilizer if you are witnessing voltage fluctuations.
- Use good quality cable for wiring to avoid voltage loss and pump performance issues.
- Pressure booster pumps are designed to be used with soft water only. Using them to pump hard water can significantly reduce their lifespan.
- Pressure pumps should be used only on positive suction.
- Do make sure there are no leakages in the pump apparatus or the suction or delivery pipeline.
- Make sure your pump operates at the duty point declared by the manufacturer for maximum efficiency. Please contact our customer support team to learn more about duty points.
- Test the motor’s continuity, insulation, and resistance using Ohms and Megger Meters.
- Regular inspection and servicing of the pump can help detect debris in the strainer or other issues beforehand.
For smooth and uninterrupted working of your pump, always follow the instructions and standard operating procedure issued by the manufacturer in the user manual.
