Blocked Hotwater tap.

[jc1]

My hot tap over my bath is blocked but all other hotwater taps work fine, i believe i need to flush the air blockage out can anybody tell me how to do this please??

if the cold is mains fed use that to push the hot water backwards pushing airlock out.

have you a mixer tap on the bath ?

strip the tap first mate and make sure all the inners are working first

 

[jc1]

Yes i do have a mixer tap can you tell me what to do so i can stop my missis moaning

its happened about 5 times before and it needs to be flushed but i cannot afford to get a plumber out again.

are you sure its airlocked ?
how did it cure before ?


if your sure its airlocked you can block the spout open the hotside and then open the cold side that will push the top backwards to clear air.
try that for a min or two it should clear.


must be cold mains to work not gravity.

Yes i believe they connected the cold to the hoit tap and flushed it??

am wi you sonray not sure about air lock how did they connect a mixer tap didnt know you could?
sorry slow typer your to fast sonray buti didnt know you could do that learn somthing new every day

what do you mean how do you connect a mixer tap ?

a mixer tap in a bathroom mixes in the tap or spout.
a kitchen mixer doesn't mixer to water leaves the spout. they have a tube inside a kitchen mixer that seperates the water.

Hi im not sure what you mean, i have a hot and cold tap with 1 spout, what do i need to do??

 

[sonray ltd]

get the wifes dish cloth and block the spout, don't need to be 100%.

hold the cloth from blowing out.
turn on hot tap.
then turn on the cold.

cause the water won't come out the spout it will go up the hot feed pipe because the cold mains is stronger pressure than hot gravity.

after about a min turn off the cold and pull the cloth out the hot should be running fast.

jc1 said earlier that they connected the cold to the hot tap? thats what i meant sorry for any confusion sonray

 

[jc1]

Thanks guys its now working do you know why this keeps happening???

 

[sonray ltd]

now you are getting me confused whats going on.

bad plumbing.
is it only on that tap ?

 

[jc1]

presures not great around the home but its mainly that tap.

not knowing the system layout etc
its getting air from somewhere that really should be going out the vent pipe and not the tap.
