Water is hot and cold help!!

[mikey83]

Yesterday i turned off the water at the mains and empty the down stairs taps and removed them and put stop ends on the hot and cold pipes i then turned the water back on and run all the taps in the houseto get out any air locks. Today i have noticed that all the hot water taps when turned on stay hot for a few seconds then go cold then hot then cold and so on. Now i am stuck to what the problem is, i didnt turn the boiler off while i was changing the taps could this cause a problem? or is it an air lock? i am now stuck so help please?

Is this your own house?

Is it a combi boiler feeding the hot taps?

You've tripped the anti DIY switch in the boiler and it will now cost you a £500 call out to have it reset.

Seriously unless you give us some sort of idea what sort of system you have we can't give any help. (May not be able to help afterwards but stand more chance)

Sorry yes its my own house and the boiler is a glow worm combi

Well first thoughts are you've inadvertently dislodged some muck that's clogged up the boiler? Has the amount of water coming out of the hot taps reduced at all? Is the cold supply fully open and flow back to the way it was before you turned it off?

both hot and cold taps flow fine just seems to keep changing temprature was not sure if me leaving the boiler on and empty the water out of the pipes would cause a problem or not?

If it has it's been unfortunate mikey83 ... I'd get someone in to check out the boiler operation ... maybe a service if it hasn't been done for a while then slip in the issue with the hot water .. that way you get a 'free' diagnosis 🙂

think this is just a coincidence turning the main on and of will not cause this problem you need to get the boiler looked at most likley cause is blocked heat exchanger or divertor valve

Thanks for your help think ill get someone round to check it tomorrow see what the problem is cheers

Hi steve the plumber did think it might be unrelated all i have done is turn off the main, remove taps, put stop ends on and turn water back i doubt this would cause a problem

LOL ... It's a occupational hazzard that if handled correctly will reap rewards in the future IMHO 🙂
