Stanley 61804N Professional Backpack Poly 4-Gallon Sprayer
Sprayer worked well today until third refill then it started spraying an air/liquid mix. I can pump up pressure but when I trigger the sprayer it sprays out an air/liquid mix that sputters and blows until the pressure is gone. Is this a problem with the seal on the pump?

Hi Chris:
Seems a bit extreme to consider using the 12 gauge. I've found that a .22 works quite well. (Humour)
Hint! Pressurized tanks must have the pressure relieved BEFORE the lid can be removed.
If the lid has been over tightened or has stuck, you'll need to get more leverage to unscrew it. Sometimes a rag wrapped around it is all it takes.
You can also try pouring hot water over the cap. Lay the tank flat so the rim of the cap gets the heat. Wrap an old towel around it first so it gets a good hot soak.
Should come off without the artillery.
Cheers
Drive out to the country side and look for a ACE or TrueValue hardware store. Bring your sprayer with you. They will likely have the right part for you in stock.
The picture looks a lot like a Solo sprayer I have. I wouldn't be surprised if Solo made them for Stanley. Do a search for Solo sprayers. They have a site. My sprayer is a Solo 425
the darker Seal has come off the plunger at the bottom of the unit , easy 5 min fix , just unscrew the allen keys at the bootonm take off the cover and remove the plunger , you'll see the plunger seal still inside you can fish it out with an allen key or similar tool clip it on again and reassemble
The solution was forthright and brief, just what I like. Thanks, Vinkumar!
