low pressure to h/w on bath

[the chippie]

hi just fitted a new bath and waterfall tap in my bathroom but the hot just trickles out colds fine (straight from the mains) thought there might be an air lock so tried to clear it by connecting the cold to the hot on the washing machine and pushing the air out all this did was fill the tank in the loft through the over flow pipe from the cylinder the flow from the tap stayed the same

Maybe its a high pressure tap.

thanks for the reply brought the tap on ebay says it needs 1 to 5 bar tank in the loft is about 1.200m
above the cylinder which is on the same floor as the bath

To get 1 bar(14.7psi) you would need to have a difference of nearly 10 metres from base of CWSC to tap outlet. So your tap is not the correct fitting for your setup.

could you tell me what sort i should get

 

[helpsy]

One that would work off, of 0.1 bar(low pressure).
