Confused about leach field
Under contract to buy this house built in 87 and has a septic system that is original to the home so a 39-year-old septic system the tank failed the county inspection because the inspector was able to pierce through the roof of the tank with a ground probe at a minimum we know that the tank has to be replaced.
However, the inspector was concerned about some what appeared to be surfacing in the yard, but after further inspection realized it wasn’t surfacing because there was no black biomass but she suspected there’s still some type of issue with the drain field. A septic company came out and recommended that we get as much water back into the tank as possible since it was pumped as part of the inspection. Over the last 48 hours we let a shower run almost nonstop.
This is a 1500 gallon tank and we were able to get the water level above the drain pipe as you can see in the photos and both compartments filled up.
The septic company said because water was able to go above the outlet pipe that there is definitely an issue with the drain field, but it is not surfacing and Given the age of the system , recommends total replacement between $32k and $38,000. We have had a lot of rain in the last two weeks. If that makes a difference.
Any help would be appreciated as to what issues could could exist since there is no surfacing in the drain field, I am still willing to buy this house, but as you can imagine, the sellers are an absolute shock at the price of system replacement
