making some adjustments for uor 2nd season. We had two 30 gal tanks pulling from the top with the 5800. there were times that the pump seemed to be working hard to get things started when applying cleaners to house or roof. This year I am looking at a standup 50 gal and a horz.65 that are plumbed from the bottom and will relocate the pump at a lower elavation in the trailer to help forse things along. How does the chems effect the fittings at the tank bottom. any advice to not chase leaks all summer. thanks TROY
