Hi All,
Pulling my hair out here...15mm tail to a bathroom towel rail. On a loop to the main 22mm flow so it is always hot, whether demand for HW or CH. Pipe is 'virtually' blocked, presumably with solidifed sludge, as flow is a cupfull per minute. Needless to say, rad is cold and the wife very unhappy.
Have tried: Sentinel 1) X400 for 2 weeks 2) Connecting mains hose directly to pipe with system drained down 3) rigged a tap-connector to a short length of hose, jubilee clipped to a bicyle valve and pumped with car pump up to about 4 bar......all to know avail.
I am reluctant to use acidic chemicals as the pipework is 26 years old.
Pipe runs under tiled floor so am reluctant to take floor up
Can't rod it as there are 2 90 degree bends in the 15mm, which is about a metre long from rad valve to where it joins main flow.
Aquavac, or equivalent, won't touch it as more suction is required.
Any ideas, please?
