Sprinkler Valve leaks

At the valve box, one valve has water spraying out. The water comes out between the bonnet and the body at one spot. I have tighted it (Hardie HR1) as much as I can. After enumerable attempts at taking the bonnet off and screwing it down again, I can make some minor change in the location of the place it sprays, but can't stop it. I know that they are not designed to have any "support" from silicone or whatever, but would there be damage if one used a little. Ideally I like to know how to solve the problem correctly of course.

The valve is now working ...

.... I don't know if I can credit the little bit of silicone I put on the rim of the bonnet where it leaked or perhaps there was just a better alignment of the bonnet with the base. The other discovery I made, actually a suggestion at the local Top Crop, was that the seal on the water outlet (in the base)was improved by reversing the rubber washer on the base of the diaphram.

Sometimes, old, stiff washers will be your undoing. Plan on replacing it next time.

Glad you found a solution.
