Whilst on the topic of blocked ****ters, the F/O a couple of weeks ago performed above and beyond the call of duty!
Despatched with one of two WCs U/S. Almost half way into a 2+ hour sector with close to a full pax compliment the CC advised that the second WC had also gone U/S, both being blocked.
The No1 CC and F/O and I discussed the pros and cons of an enroute 'tech' diversion to prevent some poor soul soiling themselves, when the F/O offered to go and investigate.
So, rubber glove on, hand into the (full) bowl, other hand working the plumbing levers underneath the bowl, and hey presto both crappers now working.
As it transpires, the defect kept recurring for a week with gingerbeers unable to find a fault until a disposable nappy was eventually retrieved from whence it shouldn't have been.
Onya ET! Can't say I'd have been prepared to do it.
