Just got my new bathroom sink up and running but I'm not the the monoblock tap is working right. The bit where the water comes out is kind of a wide thin letterbox sort of a shape and When I turn the tap on 4 separate dribbles of water come out rather than one wide torrent that I expected. There was a period of about 2 seconds where it seemed to work properly. I've not altered and pipework anything and the pressure was fine before.

Any one got any ideas?

Thanks

I assume the hot and cold are gravity fed and the tap has flexi hoses ,and your tap requires a greater pressure than what your plumbing system can provide. Thats the usual problem.

The water pressure was good with the old taps though. And we have a similar tap in the main bathroom which literally the thickness of a partition wall away and that one works fine

Old taps ? Two of them ? If so you must have had to do some ammending of the plumbing pipework ?

So what you had was a 15 mm diameter pipe to each tap. You now have a flexi hose with an inner tube diameter much less ,maybe half , taking hot ,same on cold into a monobloc. If the flexis are bent / twisted / kinked etc that will also impede the flow. Fitting isolators between supply pipe and flexi hoses ,again more restriction ( unless they are full bore isolators). You no doubt have some or all of the above . Take a look at the info that came with the tap Jamie ,you will probably find reference to a minimum pressure requirement ,that you most likely dont have .

yeah I used full bore isolators.... and the flexis are pretty much straight
