  • Sewer Inspection Report - Advice Needed!

    Hey all, we are quite far along in the process of buying a house and got the sewer inspection report back today. When we met with the inspector he seemed to think a proper cleaning would suffice. I know very little about it, however, and have some concerns around potentially uncovering more problems.

    Would really appreciate a bit of feedback! Thx.

    Sewer Report:

    The 4” sewer pipe pipe was accessed from the soil stack cleanout in the Southeast corner of the basement utility room between the furnace and toilet. The cast iron pipe flows to the West then turns North at a wye connection with the plumbing from the West side of the house. There is significant buildup of sediment and scale throughout the cast iron pipe. At 30’ the pipe turns to the Northeast. At 44’ the pipe turns to the North toward the street.

    The pipe connects to the city main between the sidewalk and curb 3’ East of the manhole. There are no significant cracked or offset sections of pipe and the pipe has positive uniform slope throughout.

    Recommendation: The pipe needs to be cleaned with a sewer cabling machine to clear the sediment and scale buildup and prevent sewer backups. No other repairs are necessary at this time.

    The worse thing that can be uncovered by removing scale and sediment from about 44' of cast iron is that it leaks from being rotted out and needs replacement ... Better to find out now than after the closing ( if you have not closed on the property yet ) .

    That's a worse case scenario ... I would go by the inspector's recommendations and have the line descaled and inspected by a camera again .

      I am a home inspector and also i perform sewer video inspections in the state of NJ. Most of the drain pipes in older homes are 3" to 4" cast iron and 8 out of 10 houses, i see enormous scale, corrosion, minor blockage, tree roots. Along with scale and corrosion build up, You should also consider the pitch of your underground drain pipe. If the drain pipe pitch is slightly positive then not too much to worry, but if the pitch is upward more then 5 degrees , then there is a drainage issue and standing sewerage inside the pipe. I always tell my clients to contact a professional drain plumber to further evaluate the situation.
