Purchased Eliminator 2 gallon spray tank at Walmart item under warranty was told to contact manufacturer who is Hudson Manufacturing from MI when tank wouldn't hold pressure they said take it apart and put lots of Vaseline on the O ring it should work. It's under warranty why would I repair it myself I thought that's what a warranty is for so you don't have to repair it yourself. BEWARE of Hudson Manufacturing from MI they make lawn products they don't honor their warranty
