New tap which won't reduce flow to a dribble *PIGLET?*

[mumblechum0]

Just about to get a new vanity unit put into my cloakroom. Last time I had one put in to the guest ensuite, the flow dropped to a trickle.

So can anyone tell me what type of tap I need to look for which will work properly? The header tank is in the loft, the immersion heater on 1st floor, and the cloakroom on ground floor if that makes any difference.

TIA

for best results, two individual taps, not a mixer tap. Put your thumb on the hot bathroom basin tap, turn it on, see if you can stop the flow. Now do the same with the cold. If not, don't use a mixer as the cold water may force its way up the hot pipe.

Bristan is a very good make.

And taps with a screwup/down knob or capstan, not a joystick or a quarter-turn spike.

If you are fitting any control/service valves, get full-bore 15mm ones by Pegler. You can also buy cheap isolating valves with a screwdriver slot at £9.49 for ten. You can guess they are not much good. As well as constricting the flow, they are liable to start leaking for no apparent reason at random times. I have even known one start leaking from the vibration when a nearby floorboard was nailed down.

The braided flexible tap connectors with valve included also constrict the flow and sometimes leak or burst.

Taps designed for a low-pressure British system like yours benefit from half-inch connectors. If you look at a flashy stylish Italian mixer, you will probably find it has two pipe tails sticking out of it, each the size of a pencil.

Thanks Piglet, knew you'd know
