Hi, I'm pretty handy in that I take on most plumbing tasks and have been quite successful. I get that pipes need to clipped to stop movement etc however, long story short there's a void in my kitchen I know I didn't clip the pipes when renovating. At night and seemingly random times when the boiler isn't running, the pipes kart like a water hammer? No taps being run and heating off. I have sat at the boiler to see if it momentarily clicks on to cause the hammer but nothing? It's an ideal logic he30 about 4 years old. No major problems and serviced. It's actually happened since it was installed but very infrequently. So I just presumed the boiler clicked on for frost protection or something. Now I'm on the sofa at 2am and it's happening loads. Help! Please. Much appreciated
