Titan Powerhorse Pressure Washer Problems: Pump & Water

A pressure washer by Titan Powerhorse can provide an excellent cleaning job for your domestic and professional applications. As a pressure washer user, you frequently need to troubleshoot various issues, particularly with the pump and the water supply network. If you’ve faced such problems with your machine, this blog post can help you fix them yourself.

Titan Powerhorse Pressure Washer Problems:

If your Titan Powerhorse pressure washer leaks water, the issue might be the pump, input hose, high-pressure hose, or spray gun. Ensure that all seals and connections are intact and tightly locked. In case of large pressure changes (either too high or too low), check the nozzles and ensure the unloader valve is calibrated correctly. If the pump produces unusual sounds or spills oil, ensure it is regularly oiled and examine its seals for damage.

For a thorough explanation of all problems related to the pump and water, I suggest you scroll down to read the following sections of this article.

Titan Powerhorse Pressure Washer is Leaking Water

If a Powerhorse pressure washer leaks water, you should check the hose connections at the pump inlet, the spray gun, and the pump itself. See if any of these sites have developed a leakage.

A leakage is more likely to occur at any of these three locations. The pump’s intake hose can cause water to leak in case of a damaged seal, and the connection between the high-pressure hose from the pump and the spray gun can also produce a leak. Furthermore, in the case of worn-out seals, the pump may cause water to escape from it and form a leakage.

● Titan Powerhorse Pressure Washer: Water Leaking from the Pump

If your Titan Powerhorse pressure washer is leaking water directly from the pump, it is certain that the piston seals are old and require replacement.

Most pressure washer pumps employ a positive displacement piston mechanism to drive water across the hoses. A piston seal prevents water entry into the pump. With time, these seals weaken and eventually cause a leak. In such a case, you may be required to remove the pump casing and examine the piston seals for signs of wear.

This applies only if you own a plunger pump. Axial and wobbling plate pumps are factory-assembled and cannot be disassembled for maintenance or repair. As a result, their seals cannot be replaced individually, and the whole pump must be replaced to remedy the issue.

● Titan Powerhorse Pressure Washer: Water Leaking from the Hose Connection

If your pressure washer’s hose connections are leaking, replace the pipe fittings/couplings at these attachments.

A pipe connector connects the pipe to the pump’s low-pressure intake, and the seal on these connections prevents leakage. Therefore, if there is a leak at this location, it is likely that the connection and its seal have weakened. Similarly, if the connection at the high-pressure output of the pump and the associated hose develops a leakage, replace the seal at the pump exit.

● Titan Powerhorse Pressure Washer: Water Leaking from the Spray Gun

If the spray gun of your Titan Powerhorse pressure washer leaks, inspect the hose-gun connection and tighten the screws. Inspect the high-pressure line’s outlet for a damaged O-ring and change it if required.

Most pressure washers link the high-pressure hose to the spray gun using a push fit. Ensure that the connector fits properly and is not loose. If it has screws, confirm that they are tight. If the leak remains after tightening the fitting, check that the O-ring on the hose is intact and present. This leak may have been the result of a damaged or missing O-ring.

Seals, gaskets, and O-rings for pressure washers are available at local and online stores.

Titan Powerhorse Pressure Washer: Water Pressure Problems

If your Titan Powerhorse pressure washer is not producing adequate water pressure, follow the steps below.

● 1. Titan Powerhorse Pressure Washer: Low Pressure

To remedy low water pressure, ensure sufficient water enters the system and the input line is not clogged with debris. In addition, check that the discharge nozzle is not damaged or obstructed.

The water entering the pump would have to be adequate to provide sufficient pressure for cleaning. Additionally, you must inspect the intake hose and remove any twists or bends. Most intake hoses are connected to the pump via a dust filter. Check to determine if dust has accumulated on the filter. If the pressure remains low after this, ensure that you are using the proper nozzle and that it is free of debris.

● 2. Titan Powerhorse Pressure Washer: No Pressure

Check the water supply, hoses, and nozzle if the output pressure of your machine decreases. Examine the unloader valve and the pump, at least one of which will need repairing.

In addition to nozzle debris and a low water supply, a loss of pressure may also be caused by a clogged nozzle or insufficient water supply. In this case, the fault is most likely with the pump and the unloader valve. Adjust the unloader valve while the pump is working, and the trigger is engaged to see whether the pressure has increased.

If the problem persists, the potentially faulty unloader valve must be replaced. Additionally, I recommend inspecting the plungers and O-rings of your pump for damage.

Cavitation-induced air bubbles may cause long-term damage to various pump components, resulting in pressure loss. Before attempting to replace pump components, see the owner’s handbook. Since most pumps are produced as a single unit, they cannot be disassembled and must be replaced with an identical model.

● 3. Titan Powerhorse Pressure Washer: Surging Pressure

If your water pressure suddenly rises, inspect the nozzle for obstructions or signs of damage. Adjust the unloader valve so that a significant amount of water enters the bypass and a lesser amount reaches the spray nozzle.

The unloader valve of a pressure washer redirects a portion of the high-pressure water flow to the pump intake or water tank instead of the spray nozzle. When the unloader valve is tightened, relatively little incoming flow is bypassed, resulting in a high output pressure at the nozzle.

The bypass flow rate is increased by loosening the unloader valve, which reduces pressure spikes at the spray gun. If this does not work, inspect the nozzle for visible signs of damage and replace it according to the manufacturer’s instructions.

● 4. Titan Powerhorse Pressure Washer: Drops Pressure after a Few Seconds

If your water pressure dips suddenly, a worn-out nozzle or a hose leak could be the cause. A malfunctioning unloader valve may also have led to this issue.

If the unloader is set too loosely, as opposed to the previous example of surging, the pressure at the spray gun may drop. If this setting is too loose, any flow might overcome the spring tension and enter the water tank. As a result, water pressure at the nozzle outlet decreases. Additionally, examine your hoses for holes or leaks. Ensure that the nozzle is not blocked with dirt or other particles.

● 5. Titan Powerhorse Pressure Washer: Strange Noises from Pump

If your pump makes strange sounds, it could be because the connecting rods or bearings are worn out. Lack of timely pump lubrication also leads to the generation of unwanted noise.

The plunger-type pumps of high-end pressure washers need oil refilling every three months. Therefore, regular maintenance is essential for these pumps to operate well. In low-end versions, the pump is either axial or plate-wobbling. These pumps need not be refilled with oil since they are permanently sealed with oil during manufacturing.

– How to Fix?

Depending on the pressure washer, the pump must be repaired and lubricated every three months (axial or plunger). Metal components not lubricated tend to rub against one another and generate significant noise. Remove the plunger pump and inspect the bearings and connecting rods if this occurs. If lubricating the pump does not address the problem, it may be necessary to replace the bearings.

If the noise persists, the connecting rods may be faulty, especially if the pump is old. If your pump has been functioning for a long time, fatigue and stress may accelerate the wear rate on its connecting rods.

If the axial or wobble plate pump on your pressure washer is making strange noises, you must replace it with an identical pump since it cannot be fixed.

● 6. Titan Powerhorse Pressure Washer: Excessive Noise

If your pressure washer makes a large noise, it may be because of broken internal pump components, air leaking into the pump, a cracked pump casing, or engine knocking due to poor-grade fuel.

– Pump Damage:

If the pump’s casing is cracked, vibrations and noise may emerge. When air bubbles get caught in the pump, it may also produce a loud grinding sound, damaging the pump’s seals and connecting rods.

– Engine Knocking:

Check the grade of gasoline in the engine of your gas-powered pressure washer if it is knocking.  I suggest using ethanol-free, unleaded gasoline with an octane number of at least 87 to avoid engine knocking. You may also see your owner’s handbook for further details.

● 7. Titan Powerhorse Pressure Washer: Oil Leaking from the Pump

The pump oil could leak due to a broken O-ring or a damaged seal. If necessary, disassemble your pump and replace each seal by hand. Contact the manufacturer for assistance if the product warranty is still in effect.

If your pump’s warranty has ended, you can disassemble it yourself. If you lack the necessary knowledge, you may employ a mechanic or contact the manufacturer. To assist with the replacements, I recommend obtaining an oil seal kit with various sizes of seals and rings.

Check that all bolts and fittings are correctly tightened during reassembly. Pressure washers should never be subjected to high temperatures to prevent more oil spills. In the case of axial or wobbling plate pumps, the only remedy is to replace the pump.

● 8. Titan Powerhorse Pressure Washer: Water in Oil

If the oil seal on the pump is compromised, water may enter the pressure washer. Consider replacing the seal in this case.

Water causes the pump oil to become milky, which is confirmed by an oil seal that has been compromised. The pump’s casing, valves, seals, and rings must be entirely removed to replace the seal.

I would do this as soon as the pump’s warranty expires. If its manufacturer’s warranty still covers the pump, it should be repaired or replaced by the manufacturer. This only applies to pressure washers with replaceable pump oil, such as plunger pumps. Most low-end pressure washer pumps are permanently sealed and must be replaced entirely if damaged.

● 9. Titan Powerhorse Pressure Washer: Soap Not Dispensing from Reservoir

If your pressure washer is not sucking soap from the reservoir, you should ensure that the nozzle is the correct size. In addition, you should inspect the soap injector kit for worn or broken components.

The owner’s handbook often suggests a specific nozzle for the soap injection function that gives enough suction pressure for all detergent kinds. Ensure that you are using the correct nozzle. If the problem persists, ensure that the nozzle on your injection kit is not blocked. A repair kit for chemical injectors may provide the essential replacement parts.
