Have you gotten many years and hours of use from the pump? If so, it may be time to replace it. However, if it is a newer pump, repair might be best. A good rule of thumb is if the repair costs more than 50% the value of a replacement pump, it is likely time to replace it.
If the replacement parts are expensive, it may make more sense to buy a new pump instead. However, if you have a high-quality pump that is used in an industrial setting, rebuilding it can be a cost-effective and efficient solution.
Pump Repairs: Seals, Valves, and Unloader Valves
Replacing seals or O-rings might only set you back $20 to $50, but if the pump's valves or unloader valves are damaged, repairs can quickly escalate to $100 to $200. A complete pump replacement is even more costly, often ranging between $200 to $500.
On some pumps, the pistons are driven by a plate on an angle (wobble plate), and in other cases, the pistons are driven by a crankshaft. Crankshaft-driven pumps are generally built better and will last longer. Low-cost pressure washers have pumps with very low life expectancies—some as low as 60 – 100 hours.

The number one cause of low or no pressure when using a pressure washer is a blocked or worn nozzle. Blocked nozzles will prevent water from escaping, while a worn nozzle will allow too much water to pass through, causing the pressure to drop.
Auto Windscreen washer pump: how much does this product cost? The price of car parts within the auto Windscreen washer pump category ranges from £2 to £109, depending on the vehicle type, manufacturer, and product specifications.
Triplex pumps featured on professional grade pressure washers can be rebuilt, but the axial cam pumps used on residential series pressure washers cannot.
Electric pressure washers often come with a lower price tag than gas models and tend to last about three to five years. On the other hand, gas-powered pressure washers have a lifespan of between five and seven years.
Triplex plunger pumps are the highest quality pressure washer pumps, offering longer life and better performance.
Depending on the size of your commercial-grade pump, a full replacement can often cost up to $1,000+. If you can get by with just a repair, expect your cost to be closer to $150 to $300.
In order to replace the water pump, the timing cover, timing chain and valve covers must be removed. This is a time-consuming and parts & labor-intensive process, which is why the cost of the repair is so high.
You'll have to match your old pump's pressure rating (PSI) and gallons per minute (GPM) with those of an available replacement. Remember, more is not always better-getting a new pump that puts out a lot more PSI can either bog down the engine, or be too powerful for your hose's burst rating.
A pump head needs smooth internal surfaces to seal properly. If you have head wash out or metal wear, it's typically not good. Also, scoring or lines internally on the brass head is an issue that will not re-seal. In either case, finding either of these issues is not good.
Axial cam pumps are a step above wobble pumps. They generally last around 500 to 800 hours and are used in pressure washers under 3,500 PSI. Axial cam pumps are efficient and lightweight. However, they have a tendency to overheat when used for long periods of time.
On average, the washer pump replacement cost is between $20 and $100 (CAD 27 to CAD 134) just for the part itself, according to data from HomeGuide.
Choose Your Pressure Washer's Cleaning Power
A pressure washer rated with a higher PSI and GPM cleans better and faster but often costs more than lower-rated units. Perfect for smaller jobs around the home like cleaning outdoor furniture, grills and vehicles.
Strange noises such as grinding, rattling or whining from the pressure washer pump during operation indicate potential problems. These noises may signify issues with bearings, pistons or other moving parts within the pump.
Pressure may decrease if your packing is worn out or if there are abrasives or severe cavitation (bubbles) in the pumped fluids. This can be caused by an inadequate amount of water and/or a lack of proper filtration.
Disruptive noises: When your washing machine makes loud, thumping sounds during the drainage phase, it might indicate that the pump has a clog or can't effectively empty the water. No washer movement: Washing machines spin and jerk quickly to loosen dirt on fabrics.
The lifetime of a water pump depends on type and model. On average, you should expect +10 years. You should also be aware of other parameters such as level of comfort provided by the pump, how sustainable, reliable and safe it is - and not least if it will enable you to save energy, water and money during the lifetime.
Replacing a car water pump could be a simple or difficult job, depending on the vehicle and the water pump's location. It's a job usually best left for professional mechanics. The water pump may be hidden under other components and may require special tools depending on the vehicle's design.
