I just purchased a wilkins model#950xl for my soon to be sprinkler system. I am just looking over the paper work that came with it and it says that, "it should be used where a health hazard does not exist in the event of a backflow situation." The next model is the 975xl which is also a reduced pressure assembly which requires a drain. I explained to the people at the plumbing supply what I was doing and they sold me the 950, but I wanted to check with the board before I went ahead with the work. Will the 950 be ok or should I return it and get the 975xl? Thanks
