Hi everyone, wow you have been more than helpful!
I just read through the follow-ups and was stunned by the comprehensive nature of the posts. My wife, five children and I are all very greatful.
For now due to our budget I think we'll have to get the valve assembly and mounting bracket. In the future though, I think you're right and we ought to spring for a new one. Do you know how often the hot water tanks go and what symptoms I should look for to tell if it's going?
We've followed the links and have ordered the parts. I also appreciate the information on the petcock. TBH I had no idea what that word meant until I googled it. Makes sense now :)
I'll reply back when I get the parts installed and working to let you know how it went.
Thanks again for all the help!
Christopher
