Thats what I was afraid of. Just hoping there was an easier way.
If the body of the valve is faulty, you have no choice other than to replace the entire valve.
Leaky Nelson Valve
I have a Nelson valve that is leaking and I cannot get it to stop. I have Nelson 7900 valves. Over the years I have had several of the valves developed leaks. I have tried replacing the diaphragm alone on some, but this normally does not work. At the suggestion of my dealer, I have started buying new valves and just replacing the "guts" of the valve. This has always worked for me. Well, I just found another leaky valve and this time replacing the "guts" of the valve is not working. I have tightened it as tight as I feel I should. I'm afraid of stripping the threads on the base. The leak is from the valve itself and not the PVC connections. I cleaned around the valve good before replacing. I really do not want to dig up around the box and replace the valve body. Is there anything else I can do to get the valve to stop leaking?
