glowworm flexicom 30cx,leak from sump

[bolan77]

i have a glowworm flexicom 30cx,it has a leak coming from sump under heat exchanger,question is does this sump have a drain hole ,right hand side towards back,as this is where water from condence comes out,any answers,thanks,this happens now and again,no pressure loss,

sounds like either your condensate is leaking or you are getting rain water intake through your flue , is there any pattern as to when this happens ? i.e. weather or when the boiler is just switched on or has been on for a while ?

There was a fault with these boilers,if you call the makers & give them the serial number they should be able to tell you if its one of the boilers concerned.

the flue has plume kit on,and has worked ok for a number of years,the condence is not leaking has i have remove and cleaned,the sump under heat exchanger,which condence trap is connected left side.the leak appears right hand side,from what looks like drain hole,if condence is coming back into fluepassing down into sump below heat exchanger and into condence trap.why would there be hole in sump where condence runs into trap,strange

Rubbish! Perforation of the sump is caused by badly adjusted gas valves, firing with an incomplete flue or a dry siphon. The fault you are referring to was noisy ignition on the old straight sided heat exchanger, it now curves like an agg timer.

However! The boiler should be turned off as products of combustion will be mixing with the air intake!!
