Further to an earlier topic of mine I've finally been up the loft armed with a magnet and sure enough I have a fatal attraction on the flow around the cold feed (not up the feed itself) which appears to be magentic for almost 6 inches upstream (boiler direction).
I have been told on this forum this could be the cause of my severe pumping over problem hence the magnet check. The pump has also started to sound at times as though it's running but not pumping then the pump seems to kick in and all sounds different.
Reading other posts is it really OK to T the feed into the vent and use this as a combined vent / feed, it's all 22mm pipework or would I be best to replace like for like?
This entire section is at least 10 feet away from the boiler so even if a temporary measure could I use plastic and JG Speedfit for the speed so I'm up and running quickly?
If I use compression fittings with jointing compound do I have to use hemp too? I've got a tub of Boss White and plumbers hemp but never used this stuff before.
Plastic would be easier if sanctioned by someone who knows.
