just having fitted a new mixer tap in the kitchen , the hot water flow to it
now is very low were as before it was ok, can anyone point me in the right
direction as to why. the cold water is fine & the hot water flow in the rest
of the house is fine. Just the hot takes ages to fill the bowl up, ive also
fitted new shut of valves into the pipe work as to aid any further work if
needed, could the taps be wrong or perhaps the valve faulty ?

many thanks.

Is it a tap that is only suitable for high pressure systems, and your hot 
water is gravity fed?

I bought some taps a couple of years back which had this problem. It seems
that the proliferation of bathroom shops may be partly due to the
availability of foreign fittings but which are not suited to many British
water systems. I complained but they wouldn't  do me an exchange, pointing
out the small print on the receipt and several not very prominent notices
around the shop explaining about it.

What size are the tails? if they are less than 15mm that is your problem

Is the pipe airlocked? if there is a high spot the air will collect there &
restrict the flow.

A crude but effective way of sorting this is to blast the air out with the
rising main.

The simplest way to do that is to [on the assumption there is a nearby
washing machine] use a washing machine hose, one end to hot washing machine
valve, one end to cold washing machine valve, turn on hot washing machine
valve, then slowly turn on cold washing machine valve.
You should hear the air rushing up to the cylinder. after about a minute
shut off both machine valves & try the hot tap, this may need to be done
several times.

There is a danger that a badly plumbed cylinder will rupture under mains
pressure so DO NOT TRY THIS AT HOME. Unless you have an umbrella handy ;-))

Saying that it has always worked for me.

you might be onto something there, by the " tails " you mean the flexi pipes
that go from the taps to the supply ? if so they do seem a smaller diameter
then the previous ones, you say if they are less then 15mm im assuming they
are too small ? , but these are designed for the kitchen or isn't that
anything to go by ?  they also have a valve in them , would this restrict
the flow ?

Presumably the valves are turned on, i.e. with the screwdriver slot going 
along the pipe not across it!  Sorry to ask but I have used lots of these 
flexis with no problem whatsoever with restricting flow noticeably.

aye the valves are turned on, they've actually got knobs to turn on rather
then a slotted screw & they seem to be turned on far enough.

could be airlocked!
