    Expansion tank - charging and system pressure

    Hi I just thought I'd add an update to this problem from a couple of months ago. Partly as I have a question, and partly because I think what's been done could be helpful for someone in the future. Anyway I did some investigating, and found that the general recommendation is for the potable...

To give a bit of history we had a problem with water hammer in our pipes so had a pressure reducing valve fitted under the kitchen sink. The local water company...
