Nice video. I ordered a Vevor 450 today and thats exactly what i wanted to do when using it next week. I dont know why nobody talks about that. A lot of guides recommend to always release the pressure by switching the valve when not in use for a few minutes. Nice video. This should be mentioned in every video and also in the user manual. 👍
I'm having this problem with my GXFF. I am guilty of topping up my machine with the pressure still high Unfortunately being such a new machine it'll take a while to get a replacement and cost a lot I reckon Thank you for your help
Maxkil if it just keeps on pumping it could be a stuck inlet or outlet valve, or pump wear. Pump wear is very slow to build up and can't maintain spray pressure, stuck valves can build zero to very little pressure, with stuck valves you can usually hear a hissing sound during the strokes of the piston.
mmm interesting, sounds about right.. I left the thing at the jobsite this afternoon and the hose has paint in it. It was working but when i tried to clean it out with water just never built up pressure, never kicked in and filled the line. Wish you were in Brisbane! I did let it run dry. Thanks for the info!
Mine was like that, primed good but was not building pressure and I found a broken ball cage inside the piston. The ball was never seating to build pressure.
Hi Ali I have a titan 640 and it primes fine. When I switch to spray it builds up pressure fine but when I start spraying, pressure drops , What that it could be? Thank you
if pressure drops but builds up again quickly, its a worn tip, if it's slow to build back up, then its the outlet valve, the outlet valve is located inside the piston, usually a little bit of rubbish causes it, however it can also be damaged or worn.
Really nice video. I have a 390 st old one that I.lost all of the manifold .any ideas on where to get a used one for cheap cause I really don't want to throw it away
you might be best just bypassing the manifold all together, that way your spray hose connects to the rear of your pump. however your gun will always be in spray mode, so you'll need to prime through the gun. they are available new but i havent seen any used ones
West Spray Airless so I can attach a different pump like the newer models ? What about the pressure control ? I would like to try that solution.can you tell me more ?
Your pump wouldnt change, but your spray hose would connect directly to your pump where the manifold hose normally connects, so you are bypassing the manifold and the drain valve
It sounds like the pressure transducer is stuck or wedged and taking time to move up and down. It'll need to be removed and cleaned. Also parts for that may be obsolete, so pay particular care when removing and cleaning parts.
mate it could be anything, you'd have to start with checking your diaphragm movement with the inlet valve removed, then you can check both your inlet and outlet valves, but thats a very general answer to your question.
remove the gun off the other end, and pump thinners through the machine, keep recirculating it for as long as necessary, just ensure your pick up filter is clean, and that the gun end of your hose has something to catch the thinners so that they're not mixing back into pick up, eg maybe use a paint strainer or stocking to catch the built up skins etc
Hey man I've got a 795 graco and the max pressure goes up only to 2300psi where it supposed to be 3300 any idea what could be the issue either than that spray fine
Hello Sir, I have a Titan XT420 that turns on but does not pumps up paint (or primes). All sprayer parts have been cleaned. This model has the sureflo inlet valve. Any suggestion to begin troubleshooting problem...?
Thanks! I have since clean the machine and installed a new piston repair kit. It now primes and builds pressure but once I press the gun trigger, it looses pressure and the machine stays on continuous without building stray pressure. The gun filter is new. Any other repair guidance will be appreciated.
@@fl9267 does that happen with or without a spray tip, without a spray tip is normal, but with a spray tip there would be another problem. eg check to see if the pump eventually stops running when your'e not pulling the trigger, if it doesn't, check your return hose to see if its releasing material, if it is, then you need to replace or repair the drain valve.
hi. i have a graco x7. it is not priming. the unit was completely disassembled and cleaned. the piston rod is clean and has been oiled with assembly lube. the X7 turns on and runs smooth, but will not prime. i tested with water, connecting suction hose to spigot. i was wondering if you think its the pump, or maybe the piston seal(s) if any, are worn? any help appreciated.
it's very hard to tell without looking, however if you go to westspray .com.au, you'll see a troubleshooting page, id suggest you look at that and go from there. I wish you the best with it.

@@westsprayairless8763 I'm sorry I took it back and got a refund..I went with the wagner control 130... It's been working great...much easier to fix when clogged
the st range came out in the late 90's, in terms of value, only you can determine that, ie if it saves you time and money and doesn't hurt your financials, then it's a good buy.
I have bought a second Hand Wagner pro 250 it’s not been used much by the look of it but when I try using it it only spit when I press the trigger after prime it seems to prime the machine fine but spray won’t come out just few spits every time I press trigger can anyone help what could be the issue
if its not a worn pump, then you will have a blocked outlet valve, this is connected to the spray hose on the machine, the outlet valve can not be stripped to clean it needs to be replaced on this model.
Ok thank you for your suggestion I will review it I thought it might be the pressure valve but that would be the last option. I hope the diaphragm looks good
@@westsprayairless8763 if it's not holding pressure and, why would it have anything to do with the gun? It's happening inside the pump somewhere so looking at the wrong end wouldn't help.
@@Tbone.357 maintaining pressure is different to building pressure, if the pump is building the pressure but the spray pressure is not consistent, then its a flow restriction in the gun, if its not building pressure at the pump then we look to the pump itself.

Hey Ali I have a Wagner 3/4 Hp model 642 and it primes fine. When I switch to spray it builds up pressure fine but the machine will not turn off once I have pressure. What might be the cause of this? Thank you sir.
Hi.. My titan 540 is not building up enough pressure.. I have recently done the whole repacking for the piston.. could it be that the prime valve is worn out and needs a replacement caz I hear some air leaking inside the prime valve.. please if you could kindly suggest a solution to that.. thank you
remove and strip the prime valve, if its a blockage it'll be easy to see and clean, if its worn (check for a groove on the ball end of the needle) then replace it. Good luck
Thank u so much for the reply. I replaced the prime valve and it was working good for an hour and after it just started leaking paint near the piston rod through the front cover. Please if you have a suggestion to that.. thank u

I took that valve off and put in a high pressure tap. Fixed the problem forever
How do you do this? I’m always just being lazy and switching between spray and prime
What if it's not leaking out the prime hose but pressure still not building up at all

I'll never loan my 840 Titan airless sprayer to anyone again. They let the whole machine out of the paint and baking n the sun. Dumb asses. 😡

You need to check your inlet and outlet valves, they may be worn or have something in there stopping them from working properly
Ok thank you for your suggestion I will review it I thought it might be the pressure valve but that would be the last option. I hope the diaphragm looks good
My magnum xr7 will prime but while spraying doesn't hold could this be the pump or packings going out?
Start from your tip and work back. A worn tip, blocked gun filter or a worn pump can be the causes.

Hey Ali I have a Wagner 3/4 Hp model 642 and it primes fine. When I switch to spray it builds up pressure fine but the machine will not turn off once I have pressure. What might be the cause of this? Thank you sir.
Benji Frizzell it sounds like a worn motor. When it's under load it shuts down, also possibly a thermal issue meaning it's not able to dissipate heat.
West Spray Airless does this mean time for a new sprayer?
Unfortunately I would imagine so. However ask your local service agent to price a motor for you, it might still be feasible to replace the motor.
