I just found my skimmer valve was leaking when I removed the loosely fitted plug I had in the end of it and found it filled with water.
The valve I used was a Hydrovalve1 1/2" ball valve and from what I can tell the boiler side of the ball is scratched and rusted badly. I can't tell if this is from debris, steam, or both?
Either way I need to do something as all I have now is a steel cap on the end of the nipple that is in the boiler. I don't feel safe with this only because I remove it from time to time and don't want to find it rusted on there.
I can't see a gate valve being a better solution as it's just going to get junk stuck in the area the gate seats in. What do other guys do? I'm thinking of trying to find a brass cap or a brass coupler and just do away with the valve.
