Are drain unblockers for septic tanks commercially available in france?

SUPERMARKETS OFFER A VARIETY OF STANDARD UNBLOCKERS Reader Question: Can someone with a septic tank use a standard drain unblocker purchased at a French supermarket? Drain unblockers of all

types are available in France.  They usually come in a liquid format which you pour down the plughole of your sink and leave overnight (or for a certain amount of time).  Variations of the

products exist in supermarkets that are quick-acting, specifically for bathrooms (to remove clumps of hair), extra-powerful for bigger blockages, etc.  Drain unblockers made to work with

septic tanks (fosses septique) are available, although you usually have to buy them from a special supplier as opposed to a normal supermarket shelf.  We found at least two brands (STARWAX

and EPARCYL) selling septic tank-friendly products on their own websites, with the goods also available through online marketplaces such as Amazon.  These are more expensive than those you

would buy in a supermarket for normal drains, however, reaching around €17 for a one litre bottle.  If using the drain unblocker does not prevent issues, you should contact an expert, as

there may be a larger problem with your septic tank. Read more: Can I install a septic tank myself at my second French home?
