Do you want to know why is my pressure washer surging? When the pressure is acceptable and suddenly weakens, it causes flooding. It occurs when the water supply can no longer support the pump’s flow rate. The pressure washer’s water flow may be limited. Inspect for kinks, leaks, and blockages in any hoses.
Ensure that all hoses and fittings are correctly attached. Make sure the faucet/spigot is entirely open. Set the pressure on the spray wand to high. Clear the nozzle of any debris. If there is even a tiny amount of dirt at the tip of the nozzle, it may cause the pressure washer to pulse. Use the nozzle cleaner included with your pressure washer to clean the tip. If not, clean the nozzle tip of any debris that has been trapped in it using a pin or paper clip. Let’s check it out.
Why Is Your Pressure Washer Surging?
Because an issue with pressure washer surging requires immediate attention, individuals will want to take the time to figure out why is my pressure washer surging? They’ll have to be patient while investigating the various ways this problem might manifest. There are multiple reasons for pressure washer surges; therefore, here are some ways for individuals to check for themselves. Let’s check the main reasons for the pressure washer surging.
#1. A damaged spray nozzle
One of the most common causes of lost pressure is using an old, worn-out nozzle. It may also tend to be one of the most straightforward solutions simplest options. All you have to do now is replace the nozzle and double-check that you’re using the right one. Don’t judge a nozzle by its color; instead, look at the orifice size. The spray nozzle must be thoroughly examined. It might just be clogged, causing the issue. They’ll need to get a nozzle cleaning kit and follow the instructions that come with it. They’ll want to make sure it’s well cleaned before putting it back together.
#2. Bad unloader valve
Specific indicators can be detected when the pressure washer’s unloader valve malfunctions. Less output pressure and decreased water flow are two of the most apparent difficulties with the unloader valve. If the valve malfunctions, the pressure washer pump will become hot, requiring additional engine power. The problem might be caused by the unloader. It has to be fixed or replaced. When the spray nozzle is obstructed, the unloader is in charge of releasing the water pressure. It is slightly above the water inlet and can be limited in several ways. Furthermore, there may be a pulsing problem in the hose. The air in the hose can be removed to check whether it will operate properly again.
#3.Water supply issue
Maybe there’s a problem with the water supply if there isn’t enough. If it isn’t the issue, the pump packings should be examined. To remedy the problem, they may need to be replaced or repaired.
Troubleshoot The Problems Of Pressure Washer Surging
Whenever you squeeze the pressure washer’s trigger, if the water pressure is intense for a few seconds before fading, you have a surging problem. Several things might cause this issue. In most cases, this signifies that the water supply cannot meet the pump’s needed flow rate. Try diagnosing the problem yourself before hiring a maintenance specialist. You might be able to save money and time by doing so. Let’s troubleshoot the problems!
#1. Replace the nozzle
Replace the nozzle and use a nozzle cleaning kit to clean it. Your spray nozzle may be partially clogged. You’ll have to replace it if you can’t clean it well enough or if it’s worn out. Check out this pressure nozzle chart.
#2. Repair the unloader
Examine the unloader and repair or replace it if necessary. When the spray flow is obstructed, the unloader releases the water pressure within the pump. It’s usually found above the water’s edge. It might be damaged or limited in some manner. Pulsating may also be caused by air in the hose. By pushing the trigger and letting the water flow, you may purge the air from the hose.
#3. Clear the water supply
Make sure you have enough water. There might be cavitation or a lack of water. If this isn’t the issue, you may have worn out your pump packings. Inspect them and, if necessary, replace them.
#4. Repair the valves
Valves should be inspected and cleaned or replaced as needed. Your input or discharge valves may be clogged. Water can enter the manifold through the intake valve. The plunger pushes the water down when the input valve shuts, forcing the discharge valve to open and release the water. It is found on the pump’s discharge side. If these valves are in good working order, your valve spring may need to be replaced. I guess it’s helpful to read about how to adjust unloader valve on pressure washer.
