Megaflo Tundish

[Steveo0189]

Hi. been called to a job with a leaking tundish, never touch these things and wondered how to go about changing it. Looks like 2 22ml comp fittings either end of the tundish, is it just a case of undoing both ends and fitting new Tundish or is there a procedure with shutting of valves etc. would app a response as the leak is enough to fill a cup or two a day. Ta chaps

you need to be qualified to work on unvented,you need to be able to see if its installed properly,a tundish is a two min job to replace

if it passing hot water through tundish its likley the ex bubble will need replenishing.
if its passing cold could need a new pressure relief valve or be a problem with the combination set.
basic service as per MI may be due!
hope this helps

you may even get away with resealing tundish if its not damaged.

as allready said must be qualified to work on these unvented units!

Yeah, i realise the implications of the qualifications etc, would'nt touch these as a rule, i am a heating engineer but not with the unvented side of things.....looked a simple swap but as mentioned not 100% on isolating valves etc. Ta

The tundish is not leaking,the tundish is just there to give a visual sign of any leakage from safety valves leaking

as said cylinder may require re priming,instruction should be on the side of cylinder
if any thing else would advise passing on to a more qualified person

If you mean the tundish is overflowing, the pipe past the tundish is probably blocked with debris. You need to clean it out through to where it discharges outside. Use a length of wire.

If the tundish is leaking because it has split at the bottom due to misalignment of the pipework, you need to fix the original problem or it will happen again.

Otherwise as the previous poster says, if it is just that you can see water passing through the tundish, then there is nothing wrong with it, rather there is a problem further upstream, in which case you shouldn't touch this unless you are qualified.

Do you have to be qualified to fit say a 10L undersink water heater (unvented)? Some posts state anything under 15L in size you don't need to be qualified others state over 15L you have to be certified. Different plumbers are stating different quotes, im left confused.
Any reliable posts would be greatly appreciated.
Thanks guys.
