SOURCE: troy bilt pressure washer will not build or reach high pressure

check the non-return valves in the pump block. if these are damaged or dirty you pressure will be greatly reduced. they are located behind the 3 lage brass hexagonal caps.

I hope this helps

Have a helper hold the trigger of the wand open while you try it again. If it starts that way you have a sticky unloader valve in the pump. DO NOT RELEASE the trigger for more than 10 seconds if the engine continues to strain when released! If the engine doesnt run freely when you let go of the trigger, pull it again and shut down the unit!
Add some power steering fluid to your supply hose (about 3 or 4 ounces at a time) and restart the unit with the trigger pulled. Allow the oil to flow through the pump for 1 - 2 minutes for each treatment. Several treatments should make the pump and valve happy again.

Hope this helps.

What is max. gpm and pis of the wisperflo punp 011773


Your question sort of requires two answers as the max flow and max psi are not the same yet relate to one another.

The max flow is ~105 gpm at ~26 ft./hd or 11.3 psi.

The max psi (head) the pump can operate under is 40 psi or ~85 ft./hd at which flow is ~35 gpm.

In other words, in a pipe system with low resistance it moves up to 105 gpm and in a very complex system with lots of elevation changes and a lot of resistance the pump will move about 35 gpm.

PSI as read on a gauge on a filter attached to this pump will NOT be the same as the ratings I am giving you here.

Hi Eglenni,

Here are the specs for your pump:

Thermoplastic Shallow Well Jet Pump 3/4 HP. This new revision of an "old hand" provides good pressure pumping from wells where the depth-to-water is 25' or less.

BODY CONSTRUCTION: Thermoplastic
HORSEPOWER: 3/4
MAXIMUM CAPACITY: 12 GPM
FLOW at 10' LIFT and 40 PSI: 9.7 GPM
MAX LIFT: 25'
MAXIMUM PRESSURE: 78 psi
PRESSURE SWITCH SETTING: 30/50
SUCTION PIPE SIZE: 1-1/4" NPT
DISCHARGE PIPE SIZE: 1" NPT
AMP DRAW (full load): 6.1 amps on 230v / 12.2 amps on 115v
VOLTAGE: 230v / 115v, 60 Hz
RECOMMENDED BREAKER: 15 amp on 230v / 20 amp on 115v
MAXIMUM WATER TEMPERATURE: 140 °F (60 °C)
=========================================
Note that this pump can be operated at 115 volts or 230 volts (A/C) It may have come wired for 230 volt use from the vendor.

Make sure the pump is piped correctly.


There should be a wiring diagram either on the pump or in the literature so you can check to see how the pump is wired.

MAKE SURE
you have the pump wired for 115 volt use in your case. Also make sure the wire size is #12 awg for the power wiring.
Make sure all connections are tight. If you have an amprobe (an instrument that measures electric current) you can check to see how many amps the pump is pulling when it runs.

You said your old pump was 1 HP. This Flotec pump is 3/4 horse so there could be some pump performance loss depending on the well depth and length of the piping runs.

Here's the link to the website for the pump. There are additional resources available on the website:

How do I adjust the pressure on an old Northstar Pressure washer. Honda 18.0 HP, GX610 V-Twin


The following link will give you great troubleshooting for all pressurewashers. http://www.pressurewasherservice.ca/serv02.htm

There are several way to increase pressure. Primary way is to turn the pressure regulator knob in the direction to increase tension on the spring. Pressure regulator is located on the pump (or very neer) and usually has a large spring. Sometimes the spring is hidden under a twist knob. If the adjuster seems to be already turned to max then you may need to just change the pressure tip. The tip/nozzle is actually where the pressure is created by restricting the flow of water thru a very small opening. Use a new tip of the same gpm flow that is required by your machine. 18 hp machine has potential for very high pressure and high gallons per minute. Use trouble shooting guide above for more information. Good luck

The pump cycles to keep the pressure constant. It could be the impeller---they sell special ones to use with nonaqueous sprays--ie petroleum based. If petro was used at some time, the impeller might be bad.

It is easy to check if your hose and quick connects are supplying enough water to the pump. Your pressure washer gallon per minuite requirements are printed on the machine and also on the pressure tips in GPM. Your post indicates 2.5 gpm but check your documentation of GPM. Next remove the tip from the wand and connect your hose with current quick connects to the machine. Start engine and direct the pressure wand into a bucket for exactly one minute. Measure the amount of water in the bucket, it should be very close to stated gallons. Do the same test with tip installed and compare measurement. If pump is starving for water you will not get proper amount of water in the bucket and the water hose will collapse. Two to four gallons of water per minute is not very demanding and should be delivered even with very small opening. You can even just direct the hose into the bucket for one minute and check how much water your hose is capable of delivering. I believe that you will find no problem with water delivery to pump. I would certainly enlighten Northern with your findings and question their evaluation. When you start using your pressure washer again try using it at lowest pressure to get the job done. Lowering the pressure to about 75% of max will increase the life of the pump and engine. Good luck with you pump
