Open Question

RY80940 The valve under the pump is leaking. I think it is a pressure release valve but I am not sure. I tightened it when I had to re attach two bolts that were holding the motor on the metal case then it worked for awhile then it started to leak and I lost all power. Should I tighten or loosen it or is there a washer that needs to be replaced?

Want to know what the black Knob, I think called unloader valve is used


Hubert, The unloader valve is like a by pass for the water and regulates/controls water pressure and redirects water when gun trigger is released. Check the attached links,instruction and guides to learn more about Pumps/unloader, Good luck

How to change out copper piping from release valve


If the release valve referred to is the pressure release valve, then a water leak out the attached vent pipe is an indication that the valve is failing. To change the valve, the water must be allowed to cool (turn off AC power or gas) and the water level inside the tank must be lowered (drained) to below the level of the pressure relief valve. Once this is accomplished the vent pipe is unscrewed from the relief valve and the pressure relief valve is unscrewed from the water tank. A new pressure relief valve with a sealant on the threads, is then screwed and tightened into place with the outlet port facing downward. The vent pipe is attached to the new valve and the tank refilled with water. A hot water facet must be opened to allow air to exit while filling. Upon becoming full (water will begin to flow from facet), turn off the facet and restore AC power or gas, therefore allowing the water heater to heat up. When the first hot water is utilized there may be some air expelled from the facet.

Replaced cylinder head due to loss of pressure and leaking. Pressure now back to normal and no leaks but machine does not switch off automatically when lance trigger released...


you may have a faulty unloader valve first remove the fitting the you attach you high pressure hose to inside inspect the checkvalve it may be stuck in the open position free it up reinstall and try again .try not to leave pump over pressurized for more than 3 seconds you will damage the seals.

High Electric Bill due to Well Pump Cycling On Frequently


The short run time of the pump indicates very litttle water volume is needed to reach to turn off pressure. To me this indicates you may have two problems. There is a leak somewhere in the system that allows the pressure to drop to the turn on point. Any check valve will fail eventually so barring any other leak that is your problem. I would think only one check valve is needed in the system so the second one may have been added to crutch the first one leaking. Normally the one check valve is placed on the pump before it is attached to the well pipe. The pump must be removed from the well to accomplish the replacement.

The second problem has something to do with the storage tank. If the pumps runs whenever you open a faucet or in your short cycle situation, then your tank is way too small or it is "water logged". Assuming it has been sized correctly, which means at least 20 gallon capacity then air needs to be added to the tank which will compress when the pump adds water until the high pressure setting is reached. When water is release to the house the air will expand until the low pressure setting is reached and the cycle repeats. The point here is that a significant quanity of water flows between pump cycles.

If your tank was installed in perhaps the last 20 years then it is likely a bladder type whitch contains the water so it never comes in contact with the steel tank, preventing internal corrosion and leaching of metals into the water. If the bladder has failed then the formally isolated air will have been absorbed by the water and your short cycling condition develops. That is what happens in non bladder tanks so air needs to be added periodically. I think all bladder tanks have a car tire like valve stem attached to the tank so that the opperating pressure can be set by the manufacture. The valve stem rairly leaks so bladder failure causes the loss of the air in the tank. There should be a label on the tank specifying the factory pressure. Use a tire gauge to test for the proper pressure. Add air if it is below setting.

2001 nissan frontier brake pedal goes almost to the floor , have bled brakes 3 times ;


Do you have any leaks? Make sure that all bleeder screws are fully tightened after bleeding. When you bleed the brakes make sure that you do not let up the pedal while tightening / loosening the bleeder - otherwise air will return to the lines. If the problem continues you may need to have the ABS system bled with a computer attached - sometimes air can get trapped in the valve block and can only be released with a computer opening the valves and a pressure bleeder attacher to the reservoir.

Low Pressure


I worked at a tool rental while attending college and had the opportunity to work on a variety of pressure washers, however, they were of the commercial type. Commercial washers are slightly different in that they usually have seperated components for easier service. Attached to the pump by fittings or rubber hose were the pressure regulator (which has the bypass unloader inside), chemical injector, pressure gauge as well as the hot water release safety all external to pump. Your pump has all these components in one case. By far the most troublesome component is the pressure regulator/unloader which when failing will result in low pressure because it will bypass water back into the intake as you suspect is happening to yours. Here are a few things to check. I believe that your pump is 2500 2.4 gpm. Test gpm water capacity by running pump normally with hose and proper tip attached. Spray water into bucket for one minute and verify that you are pumping 2.4 gallons of water (or what ever gpm your machine is rated). Measure the amount of water that your machine delivered. If it delivered proper gpm and pressure is low then problem could be worn or improper tip. The pressure is created at the tip and pressure will drop as the tip wears. As the unloader/bypass wears, water will bypass at a lower pressure. (Try lowering the pressure regulator all the way ) If water measures less than rated delivery than the machine is bypassing water due to worn regulator/bypass, checkvalves pitted, oring in front of checkvalve worn or cut or missing, or body of pump where checkvalve/oring seat is pitted allowing water to leak past valve. The cap that is removed to access checkvalve must presses against checkvalve with enough force to prevent water from leaking thru oring and body of pump. Examine checkvalves and orings with maginfy lens and look for pitting. Valves surface and orings must be very smooth and tight fitting to work properly. Body of pump where checkvalve oring snuggs against must be very smooth. Any surface where oring seats must be smooth. As water bypasses it cuts metal and orings just like a leaking faucet so look for cuts in metal and rubber. This info and my experience is better suited for larger pumps and higher pressure but maybe it will help. Good luck with your repair.

Low pressure


Anytime there is a loss of pressure it means a couple of things. the lines are not completely air tight, meaning there is a leak somewhere, possibly a valve, or a loose connection.

You have some pressure but not full pressure, which tends to make me think there is a leak. Retrace the pressure lines and tighten all connections. If that does not help, it would mean there is a crack in your pump.
