How To Tap Into An Existing Septic Tank

CountryBumkin

I've been thinking for a while almost adding a third total-bath to my single story ranch style habitation. The firm is "L" shaped and built on a slab (in FL). I want to add this bathroom at the end of the small-Fifty where there is a 2nd master-sized bedroom.

The problem is that I am on a septic tank system which is in the front end yard, and the new bathroom would be at the furthest point from that septic tank and in that location is a pool in the way.

I on my neighbors had a bathroom/mother-in-law suite added where the architect used a pump to get the waste matter from the new bathroom to his septic tank in the back. However he was able to pump in a straight line. My setup would not exist so easy.

I take a large lot (3 acres) and its pretty much clear in the lawn behind where the new bathroom would go. I was thinking I could put in a second septic tank just for this ane bathroom. My know-information technology-all neighbor says he was told that if you install a septic tank it has be large enough for all the bathrooms (or mayhap it was all the bedrooms) in the house - regardless of how many bathrooms are actually going to be connected to it. This doesn't make sense - which why it is probably true.

Has anyone added a bathroom with a small one-bath sized septic system?
Is there another way to do this I haven't thought of?

Yes, Not a DIY project, but I would like to be informed as much every bit possible before I get a general contractor involved. It also helps if I take an idea of what choices I take and then I can discuss intelligently with the contractor.

If I were to keep I would like to have professional build the shell (dry-in) and do slab and plumbing (peradventure electrical) to pass those inspections and then I would exercise the interior finishes and tile work myself.

In Washington State, the size of the septic is determined by the number of bedrooms.
That's how they figure how much utilize it will get.

Thanks Terry, and then it is probable the same in FL.

Since my septic tank is currently sized for iv bedrooms (2-one/ii baths) I would not accept an issue if I was simply adding one bathroom (no boosted bedrooms) - if I could connect to existing tank/organisation.

I would similar to call up that I could asking (and would be approved) a variance to add together a small-scale septic tank in the back for merely the one bath. I assume the lawmaking is written for one septic system per house, and my situation of course was never considered/covered in the code.

Whether or not I would continue is based on the price of this project. If adding small septic system in the back chiliad, say, adds $10K to the projection, then it is non worth it (as I don't want to spend more than $25,ooo).

Is it possible to connect the last bathroom (Bath2) the final bath on the main sewage pipe, to the new Bathroom if the new piping was to be outside of the home's slab? Tin can the bathroom pipe be under the patio concrete?
