try putting your thumb over the outlet of the tap in an attempt to clear any air lock
can you trace the pipe work to this tap?

yes pipe work goes down the wall from up in the roof,
i turn it on (obviously cold comes out the hot) till it warms up - then you get a gurrrrrrclurrcking clunk clunk noise for say a couple of seconds then all ok ??! i know its nothing major just irritating
only does it if no hot water has been run for say a day - if you redo running the water say after a few hours etc - all ok and no noise???!!

^^ tried the above hasnt made any difference but i am a bit wiser!!!
i turn the tap on and get a pretty good flow, as the hot water starts to flow through the pipe the flow gets better (with out touching the tap or turning it any more)- say after 15-20 seconds - then the water is starting to get hot! then clunk clunk clunk and the flow is at required temp?! do you think its the tap????? thank all 🙂 only a couple of clunks but i would like to get rid of them!!

anyone have any more info for me please??!
the tap / pipe dont make any noise why cold water is running through the pipe/tap as soon as it gets hot - clunk clunk clunk - water flow isnt really effected, only on this pipe/tap
i cant find any raised pipework - so dont think its air - although it does sound like it and what else can it be
its not the pipe work that is banging on anything - as its all clipped very well
im all out of ideas??!
ive replaced the tap valve but not the body.
🙁 i can live with it but still very annoying as it never did it before we had the burst!!!!

can you see air bubbles in the water ?

thanks for your reply ^ no air bubbles,
only thing it does do - which is a tiny bit strange is you turn it on - pretty good flow - just turn it a fraction - then as the hot water flow gets going - cold turns to hot the flow does get even faster - thats when its makes its clunk clunk noise - then its fine - during this time there are no air bulbbles are no spitting etc

Could be the head of the vent pipe isn't tall/long enough or the feed is in the wrong place on the pipework.
When the system is calling for hot water or heating is there water coming out of the vent pipe? Or is there suction on the vent pipe? You'll need two people to sort this. One at the F&E cistern and the other operating the heating. Heating off then on. Does water come out of the vent pipe? If not, then get a jug of water and hold it over end of vent pipe. Heating off then on. Does water get sucked out of the jug? If not then the pipework is fine and is probably a tap or something. If water comes out of vent pipe or is sucked into it then there's a pipework issue.
