I opened the tank and removed the basket but there is no adjustment knob for pressure? Am I missing something?

Mine is the same way. I am glad I read this, now I will not waste my time calling Chapin support.

I contacted Chapin Customer Support and they confirmed that the pressure regulator was eliminated as part of a rolling change (even though their manual still shows it). They moved away from that on all backpack models. Amazon needs to update their product description so as not to continue misleading customers.

If I understand your question correctly: since you are pumping by hand very difficult to set and forget a pressure setting. I pump up then spray. As pressure depletes I resume pumping moderately to keep pressure up with weed killer application continuing. It is more technique than exact science. Fill tank with plain water and practice on driveway or garden to just get a feel for what will work best for you. Hope this helps.

Not quite sure I understand the question.......the pressure is determined by how much one pumps up the tank as well as how open the nozzle is. If there is an adjustment, I'm not aware of it.

After removing the basket, directly under it is the black pressure valve. It has 4 triangular pointers on it. I believe you press down and twist to one of the other positions.

Is it possible that you have a regulator on the tank and at the grill? If so remove one. Never alter gas fittings, they are made that way for a reason.

its on top the cylinder that rises up just under the cap and strainer/filter basket, the adjustment switch is that black knob it should adjust by turning it L or R

There is no "pressure adjustment". It's a crimping tool and it does just that, crimps.

I just saw this question and I'm sure you must have it on by now but wanted to answer for others out there...I had a difficult time as well bc there's only a picture for instruction. But, I had also ordered a second small basket that came with its lid on so I looked at how that was on (just like the picture instruction) and realized I needed to use FORCE to snap it in. That's all it needed to go right on.

I've had several of these type of makers. I've never had a problem removing the basket. I usually wait til it is cool and use my finger. Are you perhaps asking about the gasket?

hope you used new gas ! i got a pressure washer that done the same thing!! i changed air filter/spark plug/(fuel filter) and replaced carburetor!!!! did not have to do any adjustment!! works like a new one.

You definitely want to be able to adjust the working pressure, as different diffusers and reactors require varying pressures. I got tow of these through Amazon, both of which were defective and had to be returned. Wound up buying a custom unit from GLA. Maybe you'll have better luck with the Aquatek.

The unit is still in for repair. The tank pressure gauge didn't work when I first pulled it out of the box. I would be very interested to see if I get an after market replacement gauge when I get it back.

You have to make sure the basket is at the highest option (arm extended so that the coil is as relaxed as possible). Otherwise it's an exercise in frustration.

I'm sorry I'm not sure about the pressure switch, I do not see any switch on it

It's been a while since I've changed mine but it just takes some effort to work the new filter over the original basket.you have to remove old filter first being careful not to break it or damage the original basket.then you have to work the rubber opening of the move filter over the basket and making sure it is completely sealed around the basket securely.that's the best way I know how to describe it.o piece you've done it once you'll catch on quickly of how to do it next time

The switch comes precalibrated for most tanks. the very first thing that you should do BEFORE replacing the switch (unless you are replacing it due to the contacts being worn out) is to COMPLETELY empty the water out of the tank, then make sure that the air in the tank (bladder, there should be an air valve like on a bicycle tire on top) is correct, if not inflate it to the specifications fro the tank, there should be a label with the air pressure settings , usually about 28 PSI or so. make sure the power is OFF, check it with a voltmeter to be sure! replace the switch. Once this is done, you can fill up the tank again and see where it cuts off and adjust if you want the preasure higher or lower. then open a water valve and see where it cuts off and adjust so that the switch cuts off at your desire setting, if the pump starts to "flutter" on and off real fast, the pressure in the tank is not correct or the low pressure is to close to the cut-off setting, lower or raise the small screw accordingly. this is what the instructions say for the bolt settings if you need to adjust it : "Turn the nut on the small bolt down (clockwise) for a higher cut-out pressure. Do the opposite for a lower maximum water pressure setting. Remember that you're not directly setting this pressure; rather, you're establishing how high you want the cut-out pressure to be above the cut-in pressure." hope this helps. and definitely test as indicated in the first answer! as this cause grief for me several times during the summer as ants...yes ants looked for cooler shelter and started to "burn up" on the contact, using a nail filler i was able to repair it for several years until there was no contact left, spraying some WD-40 below the housing helps as ants will not go onto it and it lasts longer than ant spray. : )

The regulator is probably bad. I had this same problem on this model. Had to replace the grill. Not sure why it does, but something happens and it does not let enough gas through to heat, or, no gas flow at all. I tried turning the adjuster knob slowly from low to hi and back, several times. No go.

You probably have checked this but just in case, there's a red switch in the back, make sure your water tank is placed correctly and the inlet/outlet piece's spring is moving freely. If you've checked those things already I would probably go for the diffuser assembly to make sure it's correctly attached. Hope I could help!

#1check and see if you have a o ring in the yoke if not send it back!if you have a o ring in it go to a Suba shop thay will show you how to fillYour tank

Mine is sitting in a drawer, replaced by one with adjustments. Sorry I cannot help.
