Right having slight problem with the bathroom sink hot water tap, everytime we tuen it on, it runs really slow takes ages to fill the sink. It's a new bathroom with one of those 'all in one' taps as I call them. Does. Anyone know how i can give it more pressure? If I can I want to avoid getting a plumber in.
Cheers

not a combi then, that will be your problem, you only have the pressure of the height of the water in that tank, it will be better downstairs because the tank is upstairs and therefore higher up in the house, if your bathroom is upstairs then you may only have 1.5 - 2m from the tap to tank

It's a first floor flat, we get the hot water tap not a problem in the kitchen, so why should it affect the bathroom?

ahh right, if the kitchen and bathroom are on the same floors then it could be a problem with the tap, or you could try having a look at the pipework under the sink to have a look if there is an isolation valve under there that hasnt been turned on propperly
it will look like this:

I'm having a similar problem on my bath mixer tap.
It's a mixer with a shower built in. With the shower the water runs fine, When the taps on to fill the bath it'll run ok for a few minutes then go really slow as though there's a lack of pressure.
If I turn on the cold tap on the sink or flush the toilet the water in the bath runs normal again

Could a helper pump be put in at all to give it a helping hand?

He has lack of pressure on his hot water tap. Simple.

Really?
More of the issue is why he has a pressure drop, and given its a blended tap adds a little to the problem.
So presumably the bath runs ok and the sink is run off the same 22mm feed via a 15mm tee?
I'm thinking the blender valve doesn't cross over enough

I'm assuming the bath and fittings were fitted around the time of the bathroom being extended which was roughly 1990. The boiler is a combi downstairs in the garage which I presume was installed after the bathroom was done, possibly Matt is right that the tap isn't suitable for the combo. There is an old water tank in the loft which is presumably form the old boiler.

most duplex houses use this system... due to the bottom house not having an attic to locate a water tank. the water tank is located in the hot press . the system has no 'fall'
