@myanthony, it's a horrible task trying to find something you don't know what it looks like and where it could be.

My wife’s house: 1946 3 bed end of terrace in Somerset, ASHP with rads + UFH, triple glazed, retrofit IWI in troublesome rooms, small rear extension.
The 'Y' strainer should be in the return pipework probably just through the wall inside your home.
The 'Y' strainer is not that large and could have been lagged over. If you feel along the insulation for any bumps, or if you find anything sticking out of the insulation then post a photo.
It would also be useful if you could check along both the flow and return pipework and if you find anything that is not insulated then post a close-up photo so that it can be identified.
Are you certain that any electrically operated valves are fully open?
Posted by: @derek-mAre you certain that any electrically operated valves are fully open?
That is a good point. Our UFH Honeywell valve died two years ago leading to cold zones. It wasn't responsible for the flow errors, but worth checking.

These two look like the only pipes that could release any water/blockage?
