Blocked 10mm Speedfit Pipe to Towel Rad

[bwel]

Finally unlocked it !!

I repeatedly pressurised it up to 10 bar with the pressure tester. In each cycle it took a bit extra water that would drip drip out the end. I then switched the pressure tester water over to a bit of neat X800 to push that through to the blockage area.

Finally after a few hours of pushing it through, the pressure blew out a plug of black crystals and sludge. Fortunately it did not hit the bathroom ceiling

Now I've washed the heating loop through with mains water and it should be ready to reconnect tomorrow.

I think the pressure tester advise has saved a rip out of the pipework from the walls. Thx for all the advise.

Well done mate

Had a bit of a leak on one of the 4 port Speedfit manifolds, but fixed that with a good cleaning and polishing the 22mm pipe.




I now have good heat flows in all but one of my rad circuits, except one rad. Fortunately the original Blocked Towel radiator is now working perfectly.




Whilst I have flushed it with mains water as well as X800 and thought it was heating well, it appears that there is some blockage. Does anybody know how this type of rad flows ?

Looks like I may have to remove it for a bit more of an aggressive cleaning process. Perhaps with a pressure washer in the garden.

P.S. the FLIR One thermal camera for the iPhone is amazing. Diagnoses any problems with flow and has enabled me to map my UFH circuits.

Cheers Bob
