I recently had a kitchen extension built but I'm having problems with
the hot and cold water pressure. These were both ok before the
extension.

There are, I believe, 2 possible reasons for this:

1) The mixer tap: I can't now remember the specification for the tap
but it does have two very small flexible hoses that I'm concerned are
affecting the flow.

2) The sink only moved about 2 meters but the plumber used flexible
hose instead of copper embedded in the concrete kitchen floor. I'm
concerned that these hoses may have become partly crushed.

Which do you think is the most likely cause?

Not fully opening the isolation valves after the plumbing work was
done.

I've checked the valves and all is ok.

It could be poor quality valves? It would have to be two though.

Thanks.

Is it actually low pressure or low flow? If you stick your finger
over the end of the cold tap and attempt to turn it on, does the
pressure force it off?

Most likely it's the hoses. Small ones intended for 1/2" or 15mm use
often have an internal bore of 8mm or so. This is not too bad on a
short hose, but on 2m, the flow is going to be poor.

The remedy is to get the plumber back to do the job properly. Burying
flexible hose under the floor is a bodge. It needs to be done in
proper 15mm tube. Plastic is a possibility if a little flexibility is
needed.

I've checked this and it looks like low flow.

I wont get the plumber back I'll do it myself to ensure it's done
correctly (and save a packet).

Does anyone know what BAR rating a kitchen tap should be?

Thanks.
