Hi All,
Thanks for all the help so far from this site.
Following on from this thread //www.diynot.com/forums/plumbing/gurgling-boiler.292682/
I have changed my pipe arrangement so that the feed T's in to the vent about 6 inches above the 'H' section. I done this as I wanted to try and keep the vent as an added safety measure.
Now when the pump is turned off I get hot water coming in to the F&E tank from the feed pipe, but it doesn't pump over through the vent or overflow to outside. I get about a cup of water come in, and the feed pipe gets red hot all the way up to the tank from the 'H' section, about 3 foot.
Then when the pump starts up again I still get the trickling noise in to the boiler. I have been around the accessible pipes with a magnet and the only part where it slightly sticks to is where the return from the rads and hot water cylinder T in to the return to the boiler. Could there be a restriction here causing my issues?
I'm guessing hot water shouldn't come in to the F&E tank from the feed like this. I am also worried that the F&E tank cannot take hot water and will split.
I have put some X800 in to see if that will give it a good clean out. But still seems the same.
Any help greatfully recieved.
