Pressure washers are a convenient way to clean driveways, cars, and other outdoor surfaces. However, when the pressure washer isn’t working properly, it can be frustrating trying to determine the cause of pressure washer low pressure. In this blog post, we will provide some tips on how to fix the low pressure issue on your pressure washer. We hope that you find these tips helpful!
Why is your pressure washer losing pressure?
If your pressure washer is losing pressure, there are a few potential causes. Let’s take a look at some of the most common reasons for low pressure in a pressure washer, and how you can fix them.
A worn nozzle:
The common cause of lost pressure is an old, worn-out nozzle. To fix this problem all you need to do it replace your nozzles and make sure that they’re the proper size for your system! Don’t trust what color or design on them because there could also be small differences between different models which would affect how well these work in various situations too so always check with someone who knows exactly where their supplies come from before making any purchases online
One other thing worth mentioning here: if after purchasing new equipment none seem right then send back at our expense – we’ll put something else together just as good (or better!) than anything bought elsewhere
Belt slippage:
If your pressure washer has a belt-driven pump, the problem may be that the belt is slipping. This can be caused by a variety of factors, including a loose pulley, worn bearings, or even a misaligned pump. If you suspect that this is the cause of your low pressure problem, we recommend taking your pressure washer to a certified technician for service.
Inlet plumbing air leakage:
If your pressure washer is losing pressure while in use, the problem may be an air leak in the inlet plumbing. To fix this problem, you’ll need to locate the air leak and repair it. This is typically a simple process, but if you’re not familiar with plumbing, we recommend hiring a professional to do the job for you.
Issue with the relief valve:
The relief valve is a safety feature on pressure washers that allows excess pressure to be released when needed. If the relief valve is damaged or not functioning properly, it can cause low pressure in your pressure washer. If you suspect that the relief valve is the cause of your low pressure problem, we recommend taking your pressure washer to a certified technician for service.
Clogged or improperly-sized inlet suction strainer:
If your pressure washer has an inlet suction strainer, it may be clogged or the wrong size. The inlet suction strainer is designed to keep debris from entering the pump, and if it’s clogged, it can restrict water flow and cause low pressure. To fix this problem, you’ll need to clean or replace the inlet suction strainer.
Inadequate fluid filtration:
If your pressure washer uses an oil-based pump, the problem may be that the fluid isn’t being filtered properly. This can be caused by a variety of factors, including a clogged filter or an improper filter. If you suspect that inadequate fluid filtration is the cause of your low pressure problem, we recommend taking your pressure washer to a certified technician for service.
Fouled or dirty inlet discharge valves:
If your pressure washer has fouled or dirty inlet discharge valves, it can cause low pressure. To fix this problem, you’ll need to clean or replace the inlet discharge valves.
Worn inlet, blocked discharge valve, or leaky discharge hose:
If your pressure washer has a worn inlet, blocked discharge valve, or leaky discharge hose, it can cause low pressure. To fix this problem, you’ll need to replace the inlet, clean or replace the discharge valve, or replace the discharge hose.
Restricted inlet or air entering pump:
If your pressure washer has a restricted inlet or air entering the pump, it can cause low pressure. To fix this problem, you’ll need to clean or replace the inlet, or replace the air filter.

Maintenance of your pressure washer
It’s important to keep your pressure washer maintained so that you can get the most from it. If this machine is used often on high-pressure settings, like when cleaning concrete or other hard surfaces for instance , then there will be more wear and tear on its components than if they were being operated at lower volumes with lighter loads – which means less oil needed!
The high pressure of your washer is hindered by the accumulation and buildup on all components, which needs regular attention. This includes changing out oil after an appropriate amount time has passed according to manufacturer guidelines or when you notice any leaks among other things depending upon what type it may be for example if this were gas powered then maybe look into replacing those parts first before continuing use?
If one does not clean their nozzle/filter regularly they can expect reduced performance from cleaning equipment as well!
Fixing the hose
Low pressure from your water supply hose? Check it out! In most cases, the diameter of this crucial piece is ¾” but if yours measures at only 5/8″, then you’ll need an adaptor. Before buying any accessories make sure that they will work with both types as well as having enough power for what’s needed on site – 2 GPM (Galin) or 1 gallon per minute maximum rating depending upon style used etc.. You don’t want anyone getting hurt while working hard so always be aware before using these tools responsibly
Checking the pump
If there’s no problem with how the washer is being supplied water, then the pressure coming out of its pump may be too low. Looking into this part is important to make sure that maintenance has been done when needed in order to prolong its life and usage. It may just need a new O-ring or valve seat!
Adjust the unloader valve
If all of the previous steps have been taken and you’re still having trouble with low pressure, then the issue may be with the unloader valve. This part is usually located on top of the pump, and it’s what regulates water flow. If it’s turned too far in one direction, it can restrict water flow and cause low pressure.
To increase pressure, first check your nozzle and make sure it’s not torn out. Then adjust the unloader valve in small steps to get higher PSI with each step until you reach what feels right for how much force pushes through without breaking anything! If after doing all of this there still isn’t enough power behindwater coming fromthe wand then maybe replace those pesky valves 🙂
Replace the nozzle
If the pump is working properly and there is still low pressure, the next thing you should check is the nozzle. If the nozzle is clogged or the wrong size, it can restrict water flow and cause low pressure.
Red nozzles:
This will create high pressure and help uncover those stubborn grime stains on the surface of whatever it’s cleaning! Be careful when using this accessory up close so as not damage any surfaces or belongings around them with too much force if used incorrectly
A narrow angle represents 0 degrees; therefore I recommend avoiding these nozzles at full distance from anything that could get hit (unless its an open area).
Yellow nozzles:
The easy-to use yellow tip nozzle creates a water stream at 15 degrees, which is perfect for cleaning any concrete surfaces.
Green nozzles:
This is best used for sweeping action on surfaces such as patios or driveways. It emits water at 25 degrees.
White nozzles:
The white tip nozzle is best used for light duty cleaning such as washing vehicles or boats. It emits water at 40 degrees.
Black nozzles:
It should only be used for jobs that require very high water pressure such as stripping paint. It emits water at 65 degrees.
