Has anyone on here replaced a passing Div Valve and a scaled DHW heat exchanger on a Vokera 18/72 DCMF GC 47-094-04? Very strange arrangement with large round HE on top of DV with manifold at the back? Never come across this model before, looks straightforward, but seldom these jobs are...

I deal with and know a majority of very good and competent "Technical Engineers". They are under pressure and have targets and such to meet. They all tell me if they did their job to the book, they'd do 2-3 jobs a day. What's more important productivity vs safety? We know the answer. So do...

I'm currently toying with the idea of purchasing pipe freezing equipment. I tend to end bung most systems upto 22mm. However i've never tried this freezing method nor anyone i know has. Have any of you tried it and if so what success have you had?
