Bloc Feed pipe to radiator

[Phil Redmond]

I have a badly blocked feed pipe to kitchen rad, was running very slowly but I’ve made it much worse trying to clear blockage with curtain wire, pushing the blockage to the manifold I think now totally blocked.
Return pipe is clear.
Exposing manifold is major as it’s between floors and involves carpets up and cutting floor sheets to find.
22mm pipes from combi to manifold are on the other side of the wall along garage loft.
My question is, could I T into 22mm feed and run a new 15mm pipe to rad, and use the existing return

what boiler do you have ?

 

[Phil Red]

Worcester combi boiler,
Other 10 rads and hot water fine

Then yes you will be fine coming off the main flow pipe

But your likely to get more blockages down the road with the manifold system

 

[Phil Red]

Thanks it’s another option anyway.
I’ll look into how to locate the manifold with a neighbour I know had issues.
I have a thoroughflush kit so once I get this sorted I’ll flush through and double dose of inhibitor then flush the system once a year going forward
