I purchased a newly built home 3 BR, 2 B approx 1470 sq ft on concrete slab and moved in 16 months ago. I have a 2 year home-buyer's warranty on plumbing and electrical. I live alone. I have a dishwasher I run 2-3 times a week and I run about 4 loads of laundry every 10 days or so.

My property has a 1000 gal septic tank that has two green plastic dome covers on the top. Between the septic tank and the house is a white PVC pipe that runs straight up out of the ground and it has a screw on cap.

Here is my issue.

Whenever we get more than a normal rainfall, I have a lot of noises and air bubbles coming into my toilets and if I try to flush them, they will just fill to the rim and not flush. This happened several times over the past year and a half that I have lived here but today - it became a HUGE problem FAST. I live in north alabama. We had two or three days of almost constant rain this past week. Not enough for ponding in my yard, but it just was constant. I didn't have a problem with the toilets flushing while it was raining. It stopped raining day before yesterday and this morning, I was running the sink in my kitchen to rinse dishes and I heard the air bubbles in my guest bathroom. I went in there and sure enough, the toilet was bubbling up. I tried to flush it, and the water rose to the rim. I left it alone. I went back to the kitchen, the water was standing in both sides of my kitchen sink. I went back into the bathroom about twenty minutes later and the water had gone down in the toilet. So, I decided to flush the toilet and see if it was resolved. When I flushed the toilet raw sewage water came into my bathtub rather fast from around the overflow drain cap! (I sort of freaked). I called the realtor who is partners with the builder and told him what had happened. He told me he thought I probably needed to just rinse off the filter in the septic tank. He told me how. I accessed this and the filter was not clogged at all. The water was up to the bottom of the T pipe? but not above. I went in and called the realtor I bought the house from. Told him this. He came to my house, looked in the septic tank and said "it's full", you need to have it pumped. I am the ONLY occupant of this home. I have lived here since Oct 2015. The ONLY time I have guests is during special holidays and then only for two or three days. I doubted it was full. I felt there was a fault in the field lines. I told him this. I told him I had noticed the grass in the absorption area was much thicker and higher than anywhere in the yard. He said that is how he knows it isn't the field line. He told me he uses a septic pumping company that charges him 250 to pump it out and he would call and see if he would come pump mine and let me make payments. (I am completely broke). This is suppose to happen tomorrow. Meantime, I came in and started researching. Here is what I have found. What he indicates is a FULL septic tank, appears to be in normal operation range according to research. However, he showed me the solid waste side and said "see how full it is" BUT, I don't know if the solid waste side is actually solid or if it is just the scum on the top that makes it look "solid". But, one thing I DO know. The pipe that comes straight up from the ground just outside the house with the screw in cap, does not have any sewage in the bottom of it and when we turned on my sinks inside, NO WATER came through, nor did any come through when I had my daughter go in and flush the toilet. This pipe goes straight down and ends in a T, one side goes into septic tank, the other into the house. SO, my question. WHICH IS SO IMPORTANT. I MUST get any plumbing installation problems corrected before my 4.5 months remaining on my warranty expires. I worry that if I agree to the pumping of the septic tank, that would put a band aid fix on a potential problem that my warranty should be covering that would work for about as long as the remaining time of my home's warranty. Is there someone I can call with a government agency that could come and look at the fluid and waste levels, at what is coming into my bathtub and when and what does not flow through that PVC pipe at all - that could be of help to me, so that I can INSIST that this is a faulty installation of either plumbing in the house, or field lines OR BOTH? I just can't see how ONE woman living in this house could create enough waste to fill up a properly running septic tank. The house my husband and I lived in for 24 years NEVER did this and we NEVER had our septic tank pumped. Also, this realtor and the builder he was partners for, built the three houses next to mine. I spoke to the owner of the house (exact same floorplan and size) and he had FIVE occupants for 5 years and has never had a problem with his plumbing OR had his septic tank pumped. HELP please.

If the problem only happens during heavy rainfall I would think the system was installed too deep. Another reason could be the system is being flooded if your gutters are plumbed into the septic tank or if there is a sump pump pumping into the septic tank.

The septic tank is designed to be full up to the bottom of the outlet hole in the tank. The filter is usually installed at the outlet of the tank. If the water is no higher than the bottom of the outlet, then the problem has to be in the plumbing before it gets to the tank or at the tank inlet.

From your description it is hard for me to know what is going on with the system. From what you are saying it sounds more like a plumbing problem but heavy rain should not affect the plumbing unless there is a sump pump somewhere.

As said, the tank is typically full. It only needs to be pumped out if it starts to fill with solids, but it's normal and will typically only work, if it is full to the outlet to the leach field. If the ground is saturated, the tank cannot let the liquids exit as the lines into the leach field are full, thus, there's no room for anything to come into the tank.

The leach lines can become clogged if the tank is not pumped often enough and some of the solids get pushed out rather than falling to the bottom of the tank. That can fill up the voids in the soil, preventing it from letting the liquids be absorbed as can the situation if the soil is fully saturated...IOW, there's no room for the liquids to seep into the ground.

Leach fields may not last forever, depending on the history of the tank being pumped and it being sized properly for the expected inlets...the solid wastes need enough time to settle and only liquids exiting the tank to the leach field. IF the tank is too small, or never cleaned, solids will go out of the tank, damaging and plugging the leach field.

Maybe it would be worth having an independent plumber who does septic or a septic system specialist inspect everything with a camera. The people you are dealing with are probably not on your side.

I am not a pro.

You have a a main sewer line blockage, You need to get a Plumber/Rooter company "NOT A BIG NAME" Company
to come out and snake the main sewer from the roof vent or inside clean out if you have one !
the line is blocked between the toilet and the outside clean out,

Thank you all for your advice. A plumbing company came out and inspected everything. By morning my lines had cleared on their own (which I expected them to as the ground has dried out). What was found by the plumbing company. Tanks were normal level, did not need pumping. we did flush the lines inside the house and there was a clog that came through. It is felt that as this only happens when we are having a lot of rain, it is a chain reaction. Rain, saturation, inadequate/improper placement of field line (it is a Infiltrator system) caused a back up in field, causing a slow septic tranfer, causing the toilet plumbing to lose its pressure, causing clogs in the house lines that eventually stop the flow to the clean-out pipe and septic tank and resulting in a back up of sewage into the house. As things dry out in the yard, drainage begins again and the toilet gets flushing pressure and pushes the clog through. We are waiting for the next rain to confirm this, then I expect my field drainage area to be dug up and inspected and repaired. (Hopefully). SO, being this was a NEW home, with a 24 month warranty and this problem existed when I moved in (I am first occupant). Is it reasonable for me to expect a 24 month warranty on the repaired septic drain system and tank?

No it only continues the existing warranty, when it expires it is over unless you can get get the contractor who does the
repair service to give you a warranty on their work,
YOU WANT TO GET THIS DONE ASAP next rain your home warranty may have run out unless you get something in
WRITING ASAP they may be hoping to run out warranty so they don't have to pay for repairs,
you may need to find a Lawyer who deals with this type of law

It could be more than one issue, but generally, when they install a drainage field for a septic system, they are required to perform a 'perc' test (percolation) that determines how fast moisture is absorbed. SOme places in TX have a quite nasty layer that's almost waterproof, and to get the needed percolation, they have to tear out a bunch of the soil and replace it with stuff that will allow the moisture to be absorbed. You can run into similar problems where there's a lot of clay in the soil. I suppose, it would be fairly easy to cheat on this test and only fix an area around where the test pit was done, but if that's the case, it may need a lot of work to be fixed.
