Repair on a Wilkins 375 3″ has some twists and turns

We tested several backflow prevention assemblies at one location and came across this leaky port on the relief valve cover. We started the repair thinking we could use a rubber kit on the relief valve. The inside of the relief valve cover had a groove in it where the relief valve fits into the relief valve cover. The relief valve body became stripped in 2 of the bolt holes, so instead of replacing just the relief valve cover, we had to replace the entire relief valve. Below are the different repair options for repairing the relief valve on the Wilkins 375 2 1/2″ to 6″.
