Airless sprayer wont spray


Inlet valve---9 times out of 10---

Clean it again--also check to see of the rubber hose washer on the bucket hose is not leaking--

Airless sprayer wont spray


Mike I have a hose that comes in from the top of the silver block and that hose which is about two or three feet long has a round connection with a mess inside that goes into the paint and there is another small hose that I think is a return line that bring liquid or paint back into the source of material. you are using. Where that hose is hook onto the machine is that the inlet or suction hose?When I first started this sprayer up it was not sucking so I took the hose off and put something into the hole and free some sort of spring loaded valve and then it started to suck fluid into the hose. I don't have a bucket unless you mean the same hose that have the fitting to the bottom that strains the paint before it enters the suction tube. I would take that fitting off again and soak it in acetone or some suitable cleaner. Mike I am in Florida. I am a disable soldier who like to try and stay busy to keep my sanity. Cpttrevor

The hose that sucks the paint (a section of garden hose will also work)---if that hose leaks in the least you will get the symptoms you describe---

Make sure that has a good rubber hose washer---also the inlet valve that is screwed into---the tiniest paint chip will cause the same symptoms---

I took the suction valve out and clean it thoroughly. I put it back together and the same problem. I accidentally placed the spray gun in the bucket of water and at the bottom of the gun where the hose connect to the gun or should I say the black handle piece that you grip at the bottom of that when it went into the water it cause the water to squirt like you would check a tire for leaks and I mean a big air leak could that cause the problem?

Not likely ---if the clacking sound is stopping for a while after you squeeze the trigger--the pump is not getting any paint---thus--a hose leak on the intake--or a faulty intake valve---

Try running some hot soapy water through it---also check the filter again---might have picked up some debris ----

I took the suction valve out and clean it very well it consist of a spring and a round type of stopper in the bottom of the valve. I clean all around that and even soak it in acetone for an hour. I would run the soapy water thru. I might just order a new suction valve. What role does the valve that control the prime/ spray pattern plays in this ? It sdeems like I am loosing pressure after I pulled the trigger is there a check valve in this system to prevent any loss of pressure?

The prime/pump switch is O.K. if it is working and if the clicking starts after you switch it--it is--

The inlet valve is the 'check valve' if it is not creating a perfect seal--then the pump will loose pressure when put to use---I have several on hand and change out that valve regularly---They must be able to hold back 2300 pounds of pressure--they do fail---and will malfunction when even the smallest bit of crud gets between the valve and the valve seat.

could I order that valve online if so do you know the site or any source where I can get valve. Maybe this was dirty too long and all the cleaning is not going to help. Tell me where I can get a valve and I would try again when I put in a new valve. Again thank you very much for all this helpful information. Cpttrevor

Campbel Hausefield has a site --I don't have a link---They have PDF blow ups of everything they make--helpful and friendly people answer the phones,too.

Good luck---I think the new inlet valve will solve the problem---Mike---
