Thread: Fogger Problems

Tweet

So, I am having problems with a fogger i have acquired it is a pro fogger v-945 and have completely already dismantled and cleaned the grout out. my problem is when i let it warm up and press the button for it too spray no fluid gets sucked into the line and it makes a tik sound loud and fast when the button is pressed and held. also the hose that went from the pump to the reservoir was brittle so i replaced it temporarily with a thicker inner and outer diameter hose and for it to fit cut to ends of the original and stuck it into the new one anyone know where to buy the original hose. (home depot, fish stores don't have). any suggestions?

Small hose like that can either be found at a hobby store that carries model airplane parts (fuel line) or you may be able to find something that small at a mower repair shop that has weed wacker fuel line.

Did you actually take the pump apart? Also if you have clog in the heater, the pump will lock up from the back pressure. To find your problem you need to disconnect the pump from the heater. Then you can just use water to test to see if the pump is working. If the pump shoots out water, then you have the dreaded heater clog. This can be a minor or major problem. I had to boil my heater unit in straight white vinegar for about two hours to clear a clog in the heater.

both of hobby stores and mower places where too big they were not exact but i got something to work. Now about the pump yes i fully dismantled it soaked it in a clr type substance and it cleaned it and then i air gun dried it. so are u saying i should take the line off of the heater and turn it on? or something else. Also the filter element that goes into the reservoir is that replaceable where can u find them. but yes when i turn it on i hear just a fast tsk sound and no fluid gets sucked in

Also disconnect copper pipe to heater. If the heater is clogge, you should have fog juice spraying out when you start to loosen the fitting.

Take a picture of your pump. If it is the same as mine, I can definitely help you.

It sounds like the one way valve in the pump may be stuck. If it sticks open then the pump will just suck and then push back what it just pulled.

My pump has a brass screw about 1/2 " head diameter with a flat blade slot in it. If you remove this screw you will find three o' rings. This is the pump control valve. You may have the type of pump I sent you the link too. It has a more basic design and apparently it is common for a spring to fail on this pump. This spring when broken has the same effect as when the one way valve on my pump is stuck open.

PS I think the Pro Fogger uses the same pump that I have on my Chauvet. I will describe my pump. It stands up right. The fitting to the heater sits on top. Identity on the pump could be P-8. It has a red quick release for the inlet tube. My pump uses a larger tube. Likely 1/4 " . I have a replacement pump I bought for parts. It has same components, except that the inlet size is smaller. Same style red quick disconnect. Dead giveaway is the valve. It is opposite side of inlet slightly offset from inlet.

Losi,

Here is the pump.

I will take more pictures as time allows.

u talking about this

Yep,

Here it is apart.

Nice to deal with someone who is mechanically inclined.

So lets do some diagnostics.

Take the pump apart. Leave the valve in, but get to the piston.

When the unit is together the piston is held down to nearly its full throw downward by the stronger spring on top. When power is applied to the pump the diode cuts the cycle from 60 hrz full wave to 30 hrz half wave. This in effect pulls the piston up into the coil and releases it 30 times a second. When the piston is pulled up, this is the syphon phase. When it gets released from the magnetic pull of the coil, the strong spring forces the piston back down to it's home position which is the pump phase.

If you manually move the piston up and down, you should here the one way valve responding. You should also be able to actually get the pump to draw fluid into the piston chamber.

Go for it.
