I've started to have sewer issues. My lateral has been backed up and luckily we have sewer insurance which means they will snake the line for only $50 co-pay. But after about 10 hours of snaking out baby wipes (I don't have a baby) The line is still blocked up. They said the next step would be to use a large jet machine but as you can tell from the picture it seems I'm sharing a line with my rear neighbors (who are not having any sewer issues). Since they think it's a shared line the landlord of that building would need to sign off in writing any damage that may come from using the Jet [raw sewage flooding]. I'm thinking he won't sign off on the waiver since he's been reluctant to return my phone calls. So my question is, how would you solve this issue. Please feel free to think outside the box; also remember I am a pool guy so I do have access to plumbing, chemicals, and equipment.
BTW so far my best idea is to sweeten the deal with the landlord by installing a clean-out in his basement sewer line with a shutoff valve. Right now the sewer line in his basement doesn't have any type of access or clean-out to it and I would use the valve as a barrier to stop any sewer backup from reaching any toilets etc.
I installed a 6" pvc clean-out outside my property and the sewer line in the ground is 6" terracotta
attached is an image of how the sewer lines run. ( my property ends at the sheer drop off in the image)
the estimated distance between my clean-out and probable blockage is about 90 feet.
Please, any advise is greatly appreciated
