Looking for advice on capping this sprinkler head. I have a rainbird 1800. Long story short, this head is in the middle of our patio and not needed. I bought two of the rainbird 1800 caps and both spray/leak when attached and running the line. I checked the o ring was secured inside before capping. Since both are leaking I’m wondering if the threads on the body are leaking or if there’s something else I’m missing here. Appreciate any advice!
