Bac de graise- full as a very full thing.

[Gyn_Paul]

My callendar 'binged' at me this morning with a jolly reminder to inspect the bac de graise.

On revealing it, I find it is weeping from the concrete lid which, to be fair, is not designed to be water-tight. 

I took the lid off expecting it to be confronted with a crust of solid grey fat, when in fact there were only a few clumps covering perhaps 30% of the surface area.

Nevertheless it is clearly clogged somewhere. Before I embark on the joyful task of bucketing the contents out, has anyone any experience of this phenomina ?

it is fed by 1 kitchen, comprising 2 sinks and a dishwasher.

The only time I have seen this blocked beyond the "bac" was where the tube from the bac continued into the fosse.  It was completely sealed by a plug formed of fat, the same size as the tube before it ran  into the fosse.

...as a follow-up to this, when I got down to it, I put a rake down to the bottom to see how solid the sediment was and found that with a bit of agitation, it siphoned out,  down to the proper level (phew!).  So I assume it was just sediment occluding the outlet.

Must now put a note on the callendar to inspect every 6 months !

A happy outcome.

Bit like bad constipation, then. Pity about the position of the rake!🙀🤢
