Questions And Answers

How often should I pump my septic tank?

This depends on the use. A system operating at the maximum design capacity will need to be pumped more frequently, conversely a system designed for 3 bedrooms/6 people (2 people per bedroom) but the loading is only 2-4 people will need less frequent pumping.  The contents of your septic tank should be inspected every 2 to 3 years by your septic tank contractor. At this time the state licensed septic tank pumper will open the septic tank through the inspection/service lids located in either end of the tank lid.  They will check for the thickness of the scum layer which is floating on top.  The thickness of the scum layer along with the amount of sedimentation on the bottom of the tank will determine if the tank need to be pumped.  In short, 3-5 years is a general rule of thumb. 

Why are my toilets and drains slowing down?

Several factors can cause drains to slow down or stop.  The plumbing in and under you house may be plugged with an excessive amount of debris.  This stoppage is usually very abrupt in nature.  Second, the septic tank may simply need to be pumped if service has not been kept up over the years.  This condition most likely will be more of a long drawn out process until the tank will no be able to take any more solids.  Third, as of January 1, 1998 the state required that a filter tee be placed at the outlet end of the tank as the effluent leaves the septic tank.  The filter may require cleaning every 1-3 years.  One will notice the toilets and shower drains slowing over the period of 1-2 weeks before a semi-abrupt stoppage.  Lastly, the drainfield may need attention.  This can be from age of the system, overuse, root clogging etc…  depending on the cause there is usually a period of time when the drains will slow but may appear to start working again.  This may go on until finally the drainfield will completely shut down causing a back up in the plumbing.

How do I know if I have a filter tee in my septic tank?

As stated earlier, as of January 1, 1998 the state required that an approved outlet filter device be placed in all new septic tanks.  Under some system repair conditions an outlet filter devise may have been installed in the existing septic tanks.  If you system has been repaired since January 1, 1998 there may have been an outlet filter in your tank.  An inspection of the septic tank at the time of pumping will answer this question if the company which performed the system repair cannot answer the question.

Should I use additives in my septic tank?

MBCi does not recommend using additives on a regular basis.  But, with that said, as research and technologhy progress there are products on the market which can be useful in some instances.  For example grease and oils infiltration in the septic tank and drainfield.  Grease and oils which are introduced into the system can quickly clog up the drainfield and can cause a backup in the plumbing.  MBCi does sell a product which can eliminate the greases and oils in the right conditions.  Please feel free to call us for more information on this product.
