Once the roots get into the line, you will have to cut them out or pour a chemical down the line that removes tree roots.John, I am suprised that your Post Oaks are okay around the septic system.

Wow, pretty harsh advise from noobdog1.

In any event you do need to take a harsh look at the income the rental is producing.

I'd be leerey of dumping a bunch of chemicals in, and then crawling into those chemicals.

Sorry if this sounds harsh, but advice is often cheaper than (bad) experience.all cash

Thankyou for the harsh truth and help.

I know ours are fairly harsh here in Colorado, and there are criminal penalties for violations.

It seems harsh and does cost some money, but if people are allowed to forget about it with no consequences, everybody ends up paying.

I know its harsh...

I can essentially use paint/like materials and chemicals and remodel an entire house with those as supplies.
