Leaking Water Pump

Is your water pump leaking?


One prevalent issue that plagues water pumps is the occurrence of leakages. These can stem from various factors, such as worn-out seals, cracks in the pump casing due to corrosion, or loose connections. Consequently, this leads to unwanted water seepage and potential damage to the surrounding area. Detecting and addressing these leaks promptly is crucial to prevent water wastage and costly repairs down the line.


Addressing leakages in water pumps needs a thorough inspection of the entire pump system, including its various connections and seals. Regular check-ups can help identify potential vulnerabilities, enabling prompt replacement of worn-out seals and tightening of any loose fittings.

Applying high-quality sealants, replacing faulty parts and tightening loose connections can effectively prevent and resolve leaks, safeguarding the pump and the surrounding areas from water damage. Thus, you ensure a continuous water flow throughout your entire home.

Repair Costs

If the leakage persists despite initial attempts at troubleshooting or repairs, don’t wait too long and get the expertise of a professional plumber to avoid any further damage or safety risks.

If it is an external leak, eg. worn out seals, bearing or a split in the casing, the repair costs will be approximately NZD 600-900 excl. GST.

In case of a replacement, our certified plumbers will give you an honest opinion about your options.

Clogging Water Pump

How do I stop my water pump from clogging?


Another troublesome issue is the clogging of water pumps. Reasons for this could be the accumulation of sediment, debris, or mineral deposits within the system. This accumulation can impede the smooth flow of water, leading to reduced pressure, increased energy consumption, and potential strain on the pump’s motor. Regular maintenance and periodic cleaning are essential to prevent clogs and ensure the efficient operation of the water pump.


Preventing clogging involves regular maintenance of your whole house water system, including the periodic cleaning of the pump. But also, the associated pipes benefit from regular cleaning to remove any accumulated debris and sediments. Installing filters and employing appropriate water treatment measures can also help reduce the likelihood of clogs.


If the clogging issue persists despite attempts to address it using basic troubleshooting methods, get our certified plumber on board. We have specialised tools and techniques that can effectively remove stubborn clogs and restore the smooth operation of your water pump.

If the clogs are external, eg. in the suction line, the repairs costs will be approximately NZD 200-300 excl. GST.

In the clogs are internal and we have to strip down the whole pump, the repairs costs will be approximately NZD 600-900 excl. GST.

Clogs in the water pump affect its performance. Our plumber will ensure the proper functioning of the water pump and prevent any potential water damage.

Reduced Water Flow

Why is my water pressure so low?


Water pumps may encounter a decrease in pressure, resulting in inadequate water flow throughout the house. Along with a low water pressure, you might also experience water hammering or reduced spray height. This issue can arise due to various factors, such as malfunctioning valves, damaged impellers, a compromised pressure tank, clogged pipes or air pockets. Identifying the root cause and fixing it promptly is crucial to restore the optimal water pressure required for everyday tasks like showering, dishwashing, and laundry.


Resolving reduced pressure requires identifying and fixing the root cause. This could involve repairing faulty valves, ensuring an adequate water supply, or replacing a compromised pressure tank. In addition, the impeller needs to be inspected and replaced if necessary. Check for air pockets and purge them through the air release valve if required.


In cases where low water pressure results from intricate system issues, such as compromised valves or hidden leaks, our professional plumber helps you to get to the bottom of the problem. We conduct a comprehensive analysis of the water pump and associated plumbing components, identifying any underlying issues contributing to the low water pressure.

90% of the time, the problem is caused by internal wearing of parts that must to be replaced. The repair costs will be approximately NZD 700-1,000 excl. GST, assuming the repair parts are still available. From our long-term experience, replacing the entire pump is sometimes more cost-effective.

Strange Noises

Is your water pump buzzing, humming or rattling?


Unusual noises from the water pump can indicate underlying issues that require your attention ASAP. These noises may signify problems such as air pockets within the system, worn-out bearings, loose components, or motor irregularities. Addressing these noises and identifying their source causes prevent potential damage and ensure the continued smooth operation of the water pump without disruptive auditory disturbances.


If your water pump makes strange noises, like rattling, humming, buzzing, grinding or squeaking, it is time to act. Check your water pump for worn-our bearings, misaligned parts or loose components. Align the elements, inspect and replace the old bearings and tighten the loose parts. Ensure there is no air in the system and address any motor irregularities. Identifying and resolving the source of the noise promptly can prevent potential damage and restore the pump’s smooth operation.


If the strange noises persist or worsen despite your attempts to identify the source or mitigate the issue, seeking the expertise of a certified plumber is crucial. Most homeowners are unfamiliar with the intricacies of water pump mechanisms and the associated plumbing system. Therefore, getting our plumbers onsite to assess the situation will ensure the long-term efficiency and reliability of your water pump.

If it is an easy fix, e.g. replacing a worn-out capacitor, the repair costs will be approximately NZD 200-300 excl. GST.

If it is an internal pump issue, e.g. bearings that fail and we have to strip down the pump, the repair costs will be approximately NZD 600-900 excl. GST.

Water Pump Overheating

What causes a water pump to burn up?


Overheating poses a significant challenge for water pumps, often resulting from prolonged periods of operation or inadequate cooling mechanisms. Excessive heat can lead to the degradation of internal components, such as the motor and seals, compromising the pump’s overall functionality. Additionally, overheating can accelerate wear and tear, potentially shortening the pump’s lifespan and necessitating premature repairs or replacements.

Implementing proper maintenance routines, ensuring adequate ventilation, and addressing any underlying issues are essential steps in preventing the damaging effects of overheating. This way, you provide the sustained performance of the water pump.


An overheating water pump can cause water leakage, strange noises, or reduced performance. None of this is pleasant and needs to be fixed ASAP to preserve the pump’s longevity and efficiency. The culprit could be a faulty thermostat, lack of lubrication, or high ambient temperatures. Ensure sufficient air circulation, check the oil level frequently and replace a malfunctioning thermostat if necessary.


As overheating is a common problem for water pumps, we highly recommend servicing it regularly. When confronted with the consistent overheating of the pump, calling our professional plumbers is a crucial step in ensuring the sustained functionality of the entire water system. Beyond the immediate threat to the pump’s integrity, persistent overheating can lead to further complications, potentially jeopardising the safety of the household.

When your water pump is overheating, there could be a wide range of issues. If it is an easy fix, e.g. a capacitor issue or solve an insulation issue, the repair costs will be approximately NZD 200-300 excl. GST.

If the problem is caused e.g. by worn-our internal parts that must be replaced, the repair costs will be approximately NZD 700-1,000 excl. GST.

Water pumps in transition: from costly essentials to affordable commodities

Determining whether to replace or repair a water pump depends on various factors, including the extent of the damage, the age of the pump, and the cost-effectiveness of the two options. Nowadays, water pumps have transitioned from being elaborate products to indispensable commodities. With advancements in design and manufacturing, these crucial household devices have become more accessible and reliable. When problems arise, the focus is often on replacement rather than repair.

If the water pump is relatively new and the damage is minor, repairing it might be a viable and cost-effective solution. On the other hand, if the pump is old, the damage is significant, or if repair costs are high, replacing the water pump might be a more practical choice in the long run. Additionally, manufacturers are only stocking spare parts for up to 5 years. After that, it gets a game of luck to find replacements, which increases the repair costs.
