Try force feeding the pump first, this can help to clear any dirt which might be in the valves.
you have 6 valves which are all the same , but 3 are suction and 3 are for pressure.
just take them out and put under a slow dripping tap and fill with water, if the water holds inside the valve will be ok, if it leaks just check for dirt.
hope that helps

No pressure build up from pump


looks like this is a small triplex pump.ensure the pump is acually turning over with the power unit and the love joy coupler is working properly and there is no stripped out key ways ect. was the hose jumping before the loss in presure? this could indicate a washed out in the intake or dischage valve. or debris hung up there in. check the pressure relief valve/unloader valve for proper function may be the pressurised water stream from the hose is by passing .repair /replace as required.

Low Pressure


Very little info to go on here. Could be a valve issue or a packing issue or an unloader issue. If it has been sitting for any length of time which tends to be the case, then an unloader valve is most likely the culprit. Good luck

John: I had a similar problem with a brand new CH-made compressor. The problem was not with the unloader valve, but with the check valve located where the air from the pump enters the tank. The check valve was not seating correctly due to brass filings from manufacture. The defective check valve was allowing air to escape back the wrong way from the tank to the pressure switch and through the unloader valve. This backflow from the tank would start to happen when the pump stopped after reaching high pressure. The back flow would continue until the pump restarted at the low pressure point. This cycling would continue as you described. Once I cleaned the check valve, everything (including the unloader valve) started working correctly. I hope this helps. And remember, don't work on these when they are under pressure and always wear safety glasses.

Annovi reverberi triplex preesure washer pump


Usually when a pressure washer is pulsating, either one or more pistions are not pumping. Quite often one of the check vavles for a cylider has broken and will not seal, which means you'v just lost one cylinder, and now you're running on two (etc) If a pressure washer is allowed to idle too long, re-circulating the water, it will get hot, and then melt the plastic container on the check valves. Go to : www. pressure-washer-parts.com You can order parts, and manuals.

Compressor wont restart because of head pressure


Piston air compressors have to unload to permit a restart, the two mot common types are an unloader valve or free air unloaders.

with an unloader valve this system uses a check valve mounted in the discharge line as it enters the tank, when the pump stops this check closes and does not permit the tank pressure to return to the pump. a unloader valve also opens to allow air pressure in the discharge line to vent, this valve is either on the pressure switch or on some models is on the pump, and is a centrifugal type.

Free air unloaders or head unloaders are a set of fingers that hold open the intake valves on the cylinders to permit the piston not to pump air against a head load, and once the pump is running the fingers retract to allow the pump to function as normal.

Unloader valve is the most likely suspect here.
Remove and clean with penetrating oil then reinstall.

Also add some LIGHT oil into your supply hose via a small funnel. 3-in-1 household oil or power steering fluid lubricate the valve and pump quite well. Three or four treatments of a couple ounces each will usually make the pump happy again.
Hope this helps!

Honda excell pressure washer does not have pressure


if the machine is running on suction, ie sucking out of a barrel there may be an air leak on the suction hose or pump. it will pull air easier than pulling water .

put the machine under mains water pressure, hose pipe straight from tap to pump.
check all around the pump and inlet pipes for leaks.
if water leaking this needs rectifiying for it to work on suction.
run the pressure washer while on mains pressure with the hose on, does this make a difference?

if not then probably the unloader is stuck in the pump head. remove unloader , clean and replace it
parts breakdowns are available on the internet for your machine.

possibly valves stuck, or the valve springs have broken, seen this quite few times on these machines. if so replace springs .

These sort of machines do not last very long anyway, about 50 hours use if your lucky.

No pressure unless i take the nosle off , pull trigger and put nossel back on then it's ok until i release the trigger again ?


unloader valve sticking in the pump head. remove unloader valve/ pressure reducing valve as per parts manual.

It will probably be caked up in white crystal type deposits if its an aluminium pump head. clean off the deposits and inspect the 'o' rings. if 'o' rings ok , apply silicon grease and refit.

It could also be a partially blocked lance jet not allowing enough water to come out of the lance if it is a flow sensitive unloader valve.
