20 Most Recent Stanley Professional Backpack Poly 4-Gallon Sprayer #61804 Questions & Answers

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.
