Discuss Kitchen mixer tap 3 flexi hoses in the Plumbing Jobs | The Job-board area at Plumbers Forums

Hi, I have just purchased a kitchen tap. I have extremely low water pressure and I'm having trouble finding a tap that actually gives me any water, particularly hot water. Anyway the tap I have bought says it is for low water pressure (MICOE HOME - KITCHEN SINK TAP - QHKF11) however when I opened it there are 3 flexi hoses named A, B and C. B and C are the hot and cold but A seems to go into the wall somehow according to the diagram. I have never seen a tap with 3 flexi hoses. Does anyone know if it needs to be used or have I bought the wrong tap? Thanks in advance. Pictures attached.

Can also tell you now, it is NOT designed for low pressure. Sorry.

FYI, there is NO agreed definition of low pressure. For many UK homes we need taps capable of a reasonable flow rate at 0.1Bar. Check the performance of this tap at this pressure. Because the rest of the world operates at high pressure we are out of step. For them 'low pressure' is 0.5Bar which is far too high for us backward Brits. :) BTW flow rates are logarithmic.
 
That tap is for an undersink vented water heater.
The picture in the manual doesn't quite explain it, but the one below will.
The tap hot outlet (C) is open to allow venting
Pipe (A) is the Cold feed, (Eckventil means angle valve)which is directed to the heater via pipe (B) when the hot tap is turned.

Does that mean that as I don't have one of these it's useless to me and I should return it. Ty

Hi Susan,

What might be worth looking at first is why do you have low water pressure? Is this throughout your house on all hot and cold outlets? What type of hot water heating system you have in place? All of these questions answered might help you in your quest for good hot water delivery.

Thanks.

I live in a bungalow and I have a cold water tank in the loft. I get okish cold water but my hot water is almost non existent. I haven't experienced this any where else but it is driving me mad

Is the cylinder in the loft or is that in a cupboard? Either way the pressure is going to be quite poor as it’s depending on gravity to push your hot water out. You could get your flow rate checked, and your tap I would just get a traditional compressive full operation type, such as this: Wayfair.co.uk - Shop Furniture, Lighting, Homeware & More Online
If hot water is poor to every tap, you might have an issue with the float valve in the loft, someone may have plumbed it in wrong as well, should have a minimum of 22mm pipe from cylinder.
Might be worth getting a plumber in to check it over before wasting money swapping taps left right and centre, imho of course.

The cylinder is in a cupboard directly below. I'll look into getting a plumber to check for me, do you know how much I'm likely to be charged for someone to come out ty

Anyone help me too. I have no hot water in the kitchen at all and just had a new combi boiler. Always had hot upstairs and downstairs was warm and very low pressure. Now it's still very low pressure and doesnt heat up at all. It doesn't trigger the boiler to turn on either but the boiler bloke said it wasn't the boiler. Council said it was the tap but wouldn't help replace tap. Water company said it was the boiler. Been 5 plus years of low pressure and a month now of no hot water downstairs at all. Heating does work. I was gunna change tap to prove to council it's not that. Any ideas??? I thought about valves but you'd thi k someone might of checked them one of the times they looked?? I do wonder, is the hot feed to the washer anythin g to do with it? That was capped off after a flood about 6 years ago and now it's suddenly leaking too. There is a separate shut off there and it's off.
