Re: Solution for Septic Field clogging Long Term

Philo,
Sorry to disagree with your plumber, but the 2nd chamber in your dual chamber tank is designed to accumulate sludge & a scum layer. By aerating this chamber, all of that sludge & scum will be mixed into septic soup and sent into your dosing tank and then out into your septic field. See this diagram:

You do not want all of that sludge in the 2nd chamber going into your septic field. This sludge will also clog up your effluent filter located in the 2nd chamber far too soon. Be sure that you have an effluent filter in your 2nd chamber. There should be NO sludge in your dosing tank. That sludge is coming from your 2nd chamber. That septic soup stirred up in your 2nd chamber slips right through your effluent filter. BAD BAD NEWS!

I suggest moving your aerator into your dosing tank asap, so the 2nd chamber can accumulate sludge & scum like it was designed to do.

I agree with adding a vent pipe to each lateral. It is not too late. However the best place to hydro-blast your laterals for cleaning is from a riser added to your D-Box. I am adding risers to each of my drop boxes as soon as I can find a plumber to do the job.

IMO, remove the cover to your D-Box and add a riser. A vent added to this D-Box riser will also serve to vent all of your laterals at one time. There should be room in the riser to temporarily hold any surge of liquid. I suggest a 20 inch diameter riser.

Best to you,
