Having a little pity party...

Ohhhhh, that sucks. I can't even imagine. You deserve a big vent!

Oh, what a thing to happen again!!Hope you are able to get it sorted with minimal cost and damage.

I'm surprised that your insurance didn't make you find out what caused the backup before they paid. Seems they would want to know that the issue wouldn't happen again.  If you have a clean out in the yard, call the city (or town) you live in to see if they can camera your line and ask them to make sure that the main sewer line is clear.  We will do both -at no cost to the homeowner but your line has to be clear first. Sorry you are dealing with this again! Good luck.

was there recently any road work done? when we moved into our first home, we had a big sewer backup the first time we did laundry and took showers afterwards. the problem turned out to be when the city ran public water down there 7 years prior, they had plunked a big concrete storm drain culvert on a portion of the rubber elbow where our sewer line entered the street. apparently the elderly gentleman who lived in the house prior had never used enough water at once to cause a backup, but we did straight away. we spend about $400 on a plumber and rooting it ourselves before the roter rooter guy told us the county would video scope the line for free since the problem was apparently at or in the road. they did, and that's how we found out the problem. city fixed it for free too.

hope you find out the problem soon! doesn't it just figure that you had no issues til right before you list the house? sigh. I hate it when that happens.

Oh, I feel your pain. The first time we had this happen it was at the county's end so they fixed it. Luckily I had very little damage inside so didn't have to bother with insurance. The next time it happened my house was already on the market. We caught it fast so once again little interior damage but we had to stop showing for a week. They were able to replace the pipe without destroying my front yard too much and it actually helped that we were able to say that the line had been replaced since our house at the time was 24 years old.

Hope you find the problem and get it fixed once and for all so you can get your house sold.

Oh, I am so sorry. This is worthy of a HUGE pity party.

I think you are on the right track, have a camera run down the line.

I hope it's an easy fix.

My daughter and her husband had these problems the very week they moved into their new home with a brand new 3 day old baby. Sewer backed up into the basement. It was so gross and such a mess. The plumbers found a root and evidence the prveious owners have had problem before. The septic was also full and had to be emptied, all of which my daughter had to pay for. The plumber said should have been found during inspection but I guess not. It was such a mess.

Go ahead and have that pity party. Life can be hard and not what we want at any given time.

OH I am so sorry, that stinks. I hope you can get it fixed with the plumber.

ARGH! This just sucks. Hoping it's easily resolved w/insurance and that you have an easy sale and quickly.

Okay, here is my story.

We have a 40 year old house with 40 year old pipes. House never had a disposal before we moved in 15 years ago. Previous owners shoved everything down the sink. 6 months after we moved in - backup in the house. Had the ENITRE house snaked plus from the house to the main service line. Exactly one year later, another back up. Again, snaked to the main line. We have also had problems with a massive water fly infestation. It is common in the neighborhood but it was REALLY, REALLY bad. Exterminator had never seen a house with that bad of an infestation. We spent a lot of money on toxic chemicals to keep it at bay. We never used insurance because it simply was a matter of cleaning it up and cleaning a spot on the carpet.

I was so tired of worrying that we would have another backup so we had the service line from the house snaked with a camera. All of my neighbors have had to have their service lines replaced due to age. They found a low spot. We had to replace just that part but when they excavated they also found a small break. The fly's were living in the standing water in the pipe. We have no trees in the front to break through. We now have an access pipe to the surface in the middle of the yard so they don't have to snake as far if it ever happens again.

Since your house is new,  would probably assume you have a broken or shifting pipe if you don't have any roots.  I doubt in 3 years the roots would get through if they were new plantings.  You need to run a camera.

You absolutely deserve to have that pity party. I've been through something similar and it was not fun. Fortunately we weren't in the process of trying to sell the house as you are. I am sorry you are dealing with this and you have every right to be distressed. I wish I knew something to say that would make it better.
