Professionally rebuilt. Filter gone through, new main gasket, new stainless steel bolts/washers/nuts all around, all new orings, new top, new handle and ready for the next 30 years. I have lots of spare parts, stainless steel hardware, extra main gasket and finger filters to go with it. The only thing that I didn’t replace was the pressure gauge. Even if you want this for parts it will save you thousands because that what it cost me. Two69-five99-2three31. Call or better yet text. I may even be able to deliver it.
