Fosse Septique - Un Coude Plongeant

Our new home has a non-conforming Fosse, because of the requirement: Mettre un coude plongeant en sortie de bac a graisse / Put a plunging elbow at the grease trap outlet Anyone have experience of having this done? and a recommendation:- Faire attention au niveau d’eau anormalement eleve de las fosse / Pay attention to the abnormally high water level in the pit Is that likely to be a major issue? Thanks in advance for advice Graeme
