Just had a thought tom (which you've probably already done if it works)!
If you turn the valve to the heating on the boiler to off it should stop the heating warming up when drawing off the hot water?
Don't know why I've never thought of this before?

I'm not sure i understand you tappy, I have a Baxi combi, Do you mean the valves on the flow and return to the heating ? I've never thought of doing that and not sure if its dangerous because, the boiler is designed to ' dump' into the heating if there is something wrong and to be honest, it could be the board not doing what it should, But yes, that's good thinking Tappy, I'll try that and monitor the boiler while the hot water is drawn off and come back and tell you what happens,  |

Yes, that's my idea - if the diverter's passing onto the heating when drawing off the hw and you physically turn the heating off - the faulty valve can't pass? Might save you a bob or two in gas until you can fix that diverter valve. Never thought of doing this before, it should work.......?  I once shut my heating off on the valves on my Baxi and then drained it to do a re-pipe on the heating. I just ran it on the domestic hot water side for about a month. I've noticed that some of the gas service guys who don't want to get stuck with changing a slightly faulty diverter valve job when the customer complains that the hot waters not has hot has it once was just throttle down the hot water flow rate so that it becomes hotter at the taps as a "quick job get away". Not me though  ? |

good suggestion that Tappy, anyway guess what, both valves have siezed, I've tried grips on one and it broke the plastic valve head, So Its a diverter valve and two isolator valves job now, Which as it turns out, I will be prepared for both jobs now, had I not been, I would have found out on the day and would need to go out and get two which would cost me time and anxiety, So well done Tappy for preparing me properly, I love this forum me,  |

Ah well, that's just typical of this plumbing trade. Glad my suggestion (although it didn't work out) was of some use to you in the end  |

the funny thing is Battle, I've had anxiety all my life, I thought it was normal, I did't know it was an illness untill recently when I found out people actually have time off for it and get paid for it, dislexia is another i've had all my life, In my skool days I was told i was thick because dislexia had not been invented then, I've also hear people getting time off ( paid) and treatment for BPD, (Borderline personality Disorder)  fucking hell, If I've not got that as well, no one has,  |

Glad my suggestion (although it didn't work out) was of some use to you in the end It did work out well Tappy because I managed to close one valve with a bit of messing about, then ran the hot water, the water ran hot continuous and no rads came on, this proves it is the valve, So coming soon near you, a video of my home spun power jet machine as a warm up then pearl and dean and kiora orange juice, then the main feature changing a diverter valve, 10/6d stalls 2 bob circle, |

Finally got round to doing the video, its uncut and shows the job start to finish including seized nuts awkward spaces about 40 minutes long and shows what plumbing and boiler repairs are not for the faint hearted, I did't change the valves nor do the powerflush because, I was on the clock, Mrs Plum went out but only for about 4 hours and doing those jobs would have put me under pressure, So I'll do those another day,
It might bore you shitless or put you off ever touching a boiler, either way, its live plumbing at the spearhead.

 Great video Tom, with all the troubles one gets yet which many others never show in their clinical productions.

thanks Battle I did it that way to give a clear picture, If I edited all the faffing about its quicker to upload but, it gives a false story of whats going on and folks can get unstuck, any plumber will tell you, a half hour job, which that should be, can take all day and, even a return visit because you have other work booked in or a part is faulty or, a bit is missing and loads of shit can go wrong, So that was the message, I'm glad you enjoyed it, |

Enjoyed watching that tom, it was different and could even be a first - a diverter valve replacement in real-time.
Good to see the forum grips still going strong and looking good as well, well better than mine anyway!
Although looking a bit battered now they are still in use, albeit after a small brazing repair job when the nut came apart.

Cheers Tom
When you said the hot keeps going cold.
How do you diagnose it’s the diverter valve rather than a blocked plate or other component?

Cheers Tom When you said the hot keeps going cold. How do you diagnose it’s the diverter valve rather than a blocked plate or other component? the main tell tale sign was, When we run a bath, some rads get hot as well even thou the heating is off, The other thing is, when running the shower, the temp will vary, Our shower is a manual type and once set to a temp should stay at that temp if all is well But, its not doing, it will go cold as the diverter moves over and does not give priory to the water, I'm hoping this fixes it now, |
