OK, thanks for the advice and all the help you have given.
I am a bit reluctant to take the boiler apart just now as we need it running with central heating all the time at the moment, so might wait a couple of days.
The boiler spec is Baxi Duotec 40he
Thanks again
Yes cold fill at boiler was from filling loop.
The flow at the hot taps is 5.25 to 5.50 lt/min and the flow into the boiler is 6.00 lt/min which is not much different.
I thought that this drop of max 0.75 lt/min may just be due to the normal restrictions through the boiler and that's why I...
Sorry for the late reply.
Yes the flow has slowly got less and less over the last few days.
Here are the flow test results from each hot tap.
Sink Tap nearest to boiler 5.25 lt/min
Sink Tap furthest away 5.50 lt/min
Basin tap upstairs 5.25 lt/min
Bath tap upstairs 5.50 lt/min
For reference...

I did actually measure the cold water flow through the inlet tap by disconnecting the filling loop and filling a bucket.
I filled the bucket for 30 seconds and marked a...
Hi,
Yes all taps have reduced flow and we do live in a hard water area.
I have just measured the cold water flow through the inlet tap on the base of the boiler and this seems very similar to the measured flow from all of the hot taps.
When compared to the flow from cold taps it seems about half...
Hi,
I have a 3 year old Baxi Duotec combi boiler and over the last few days the pressure/flow of the hot water to the taps has decreased considerably.
There is a noticeable sound of the water passing through the boiler that was not present before.
I have checked/cleaned both the water inlet...
Hello,
This is a long shot, but I have the exact same problem with my boiler and was wondering if you found out the reason for the fault on your boiler.
Thanks for any info you could give me.
