I built recently and instead of a septic tank I was required to but in a waste water treatment bioi-cycle unit. It cost about 5k and the service cost about €200. Now I am being asked to pay another 200 for next years service. Does anyone know do these units need and annual sevice or is it something that could be every 2 years or a filter replaced by myself?
Thanks for any suggestions or experience in this area.
200 euro is cheap, they are asking me for 275 euro for next years service, threatening that the cost will be high if contract is not in place and the unit breaks down. Are there any independent (non biocycle) service folk who service biocycle units?
