We've got tenants that are flushing tampons and I keep getting clogs.  

Most of the possible issues brought up sound like cautionary tales in general...and issues that should be mostly flushed out during DD.As the numbers run as is...this park will make money.  

Also, if you get one, buy the flush kit valves ($100).

Septic tanks work great when you control what goes into them, not so well when you have no idea what your tenants are flushing down the drains and toilets - grease, wipes, etc.

Liar loans have basically been flushed through.It seems like only the strong will survive...

Some may, most won't, so if your strategy depends on this you'd better flush it out sooner rather than later.Good luck!

Welcome Chad,I'm a newbie myself, originally from Flushing, NY, now base in the Philly area.

I would attempt to save the existing drain field, perhaps it may only need to be flushed; have your septic guy give you some alternative suggestions and make the replacement the last choice as it is the most expensive.  

Save the work for when you are felling flush.

They did, but of course they didn't clean the place when they left, and they flushed a washcloth down the toilet and we ended up paying the week's worth of water/sewer.Anyway....a bad vibe at this point won't likely get better.
