Drain field help

Have drain field that is about 30 years old. Started backing up last year. Pumped out just over 12 months ago, now backing up again.

Question is are there any treatments that people really have experience with?

I'm thinking of opening the distribution box and pouring in sodium percarbonte. Also read that could put.an aerator in the septic tank, or.possibly jet out the leech field lines?

Any advice and experience with this is appreciated. This is a home in Florida with basically sandy soil.

Open up a hatch of the septic tank and look in. If you hava a backup and the water in the septic tank is the normal 9 or so inches below the top then there is a blockage upstream towards the house. If water is up to the brim and stays that way for hours then you have a problem downstream.

You can have the main lines into and out of the septic tank videoed for obstructions. The technician has to be careful not to break the baffles at the septic tank inlet and outlet and to have those repaired if needed.

You probably need to have the leach field rebuilt or, if you have enough land, a new leach field built next to the existing one. This is not a do it yourself job in most cities and towns.

Chemicals do not work well for cleaning the leach field because you need stupendous quantities to achieve enough concentration to do the job over the many feet of leach field lines. Then it becomes highly environmentally hazardous. Jetting the leach lines does not work because the blockage is just outside the pipes.

A friend had his drain field jetted with fair results. His biggest issue was an overused system [family too big] and not enough land to expand the drain field. He ended up moving.

I used to live in central fla and had an old system with only 80' of drain field. Extending it 40' helped a lot.
