In a buyer-friendly market, home shoppers can be pretty particular in their search for a dream home. Increasingly, buyers are seeking flawless, move-in ready homes, and while traditional home inspections are a must-have, something equally important lurking beneath homes often goes overlooked.

A sewer line inspection is not included in the standard home inspection and is regularly waived in the purchasing process. Additionally, many buyers do not know that responsibility for the condition of the lateral sewer line leading from the street to the home lies with the homeowner, not a municipality. Buyers should reconsider including this important step before they sign a deal.

If a problem occurs, a sewer line replacement costs at least $4,500, but prices vary widely and costs increase dramatically by region, depending on depth and length of the underground pipes and if street repairs become part of the issue.

Experts at Roto-Rooter, North America’s largest provider of plumbing repair and drain cleaning services, encounter this scenario far too often. Consumers, who just signed the dotted line on their dream home, soon find that they’re trapped in an expensive plumbing nightmare.

“Just a couple of years after purchasing our home, we had a $15,000 sewer line disaster in our lap,” says Jennifer Schappacher of Cincinnati. “The sewer line clogs began not long after we moved in, but as they became more frequent we had Roto-Rooter inspect the line with a video camera and only then did we realize the pipe had offset sections and a partial collapse that was causing sewage to back up into our house.”

The Schappachers looked at only a few houses before deciding on one in a quiet shady neighborhood. It was charming with large, mature trees that shaded the entire street. But since the house was built in 1959, its concrete and clay underground sewer pipes were vulnerable to heavy root intrusion from the big trees. As those roots entered the pipe joints in search of water, they pushed the pipes apart and allowed surrounding soil to spill into the pipe, narrowing a 6 inch diameter pipe to just 1 inch in some sections.

Generally, a plumber can complete a sewer line camera inspection for $250 to $550, depending on the region. While not cheap, it’s a relatively small price to pay when buying a home, especially if it helps a buyer avoid thousands of dollars in unforeseen repair bills.

To avoid unexpected and costly plumbing problems, the experts at Roto-Rooter recommend having a plumber conduct a video camera sewer line inspection, in addition to a standard home inspection, before buyers purchase a home. The process involves passing a waterproof fiber optic video camera through the pipe. The specialized cameras are equipped with bright LED lights so the inspection will reveal any cracks, breaks, offset or collapsed sections of pipe. The plumber will often provide a DVD copy of the inspection as part of the service.

“Sewer inspection camera equipment is expensive and often is only utilized by well-equipped plumbing companies, but the video inspection service itself is easy to complete and well worth the extra step,” says Roto-Rooter master plumber Larry Rothman.

Root growth is the most common cause of sewer line damage and is often responsible for blockages and separated pipe sections. Outdated and eroding pipe materials are also a common culprit in sewer line deterioration. Older pipes are much more susceptible to root intrusion than new plastic pipe.

Inspections are especially important if:

* The home is 20 years or older.

* There are mature trees around the property.

* The home has been vacant for a period of time.

* The concrete surrounding the home is cracked or raised.

* There is considerable visible root growth in the yard.

Many homeowners, especially new homeowners, do not know or think about their home plumbing. For seasonal maintenance tips and general information, visit Roto-Rooter’s plumbing basics section online at http://www.rotorooter.com/plumbing-basics.
