I've now successfully cleared the return pipe from the towel rail. Had to cut up the floor boards to get access to the 90 degree connector, connecting the plastic pipe to the copper tail. To my surprise this connector wasn't the issue! When I remove it I pushed some wire into the pipe and about 0.5 metre in it hit something solid, but I was able to eventually push through it. Got lots of solid sludge on the wire! I then realise there was a straight connector at this point of blockage, so clearly the pipe inserts had provided something for the sludge to build up against. I guess pipe inserts are one of the issues with plastic piping and an advantage of copper piping where the bore doesn't get reduced.
Having cleared the blockage with wire I was then able to flush the pipes through and clean out the crud. Tonight I'll be re-connecting the towel rail, with some new valves and will push more water through to flush again and to ensure the joints are water tight. In the morning I'll re-connect the towel rail to the CH system.
Regarding the original wiring of the loft radiators and towel rail, I'm wondering if the orientation of a T connector can make any difference to the flow of water. In particular on the return side, which seems to be the worst blocked pipes. Here's what I mean:
On the left is a diagram showing the orientation of the T connectors as they were. The return from the Loft en-suite towel rail and loft 1 radiator is potentially pushing against each other and causing a resistance. Same when that (reduced?) flow hits the flow from the loft 2 radiator prior to going down the copper pipe.
I wondered if changing the orientation of these two T connectors might help the return flow as shown in the diagram on the right. In the alternate diagram the flow from the loft en-suite towel rail has an "easy path" and I wonder if the flow from loft 1 would not give as much resistance. Same with the connector from Loft 2.
Or am I talking rubbish?
