Thank you for that. Sadly there is only about 3 metres from the tap to the cold water tank, as we have a low-pitched roof, and the tank is on the loft floor.
I guess I'll have to have a normal tap and fit one of those screw-in sprayers to it.
Thanks for the reply. I just wanted to replace the tap with minimum expense and fuss. If necessary, I'd rather go without the pull-out spray, than have to install a pump.
Thanks anyway.
Is there a pull-out spray tap which will work with a gravity-fed hot water system? I need to change my kitchen tap, I like the idea of the pull-out spray, but all the ones I've looked at say 'high pressure' or 'minimum pressure 1 bar or 0.5 bar'. I think my hot water pressure is less than this...
