I just registered on the forum because I need your advice. I have just bought a house which is not connected to the whole to the sewer and which is equipped with a micro station. Everything is in order according to the SPANC and the oil change was done not too long ago. However, this is my first purchase and I am not really familiar with sanitation!
Can you tell me how often to change the oil? I looked on the internet and found this:
“When the volume of sludge reaches about 30% of that of the primary settling tank, it is necessary to empty it.
In general, this operation is done every 2 years, but this frequency can also vary depending on the number of occupants of the accommodation or the size of the device.
However, you should not limit yourself to this parameter if you want to define exactly how often your micro-station is drained. It is also necessary to consider the number of real occupants of the dwelling. "
(the source of that is here: https://www.prixmicrostation.com/cout-entretien-micro-station/)
It's not really clear! How to assess the volume of sludge? What happens if we reach more than 30%? They say that during the annual maintenance, the specialist gives an approximate date but since I just bought the house, I don't have a date!
How much did you pay for your annual maintenance? On this site, they give a range that could not be wider: between 50 and 500 euros !! Not easy to calculate the budget in this case!
Thank you for your opinions and testimonials! Have a lovely day everybody
