Old concrete and clay pipes were installed mostly in 3’ sections. Over many decades of the ground shifting and settling, these pipes can get moved around; and due to the short pipe lengths, they are not always moved in a way that allows good flow from the home to the municipal sewer system. Often times, pipes are moved up, which certainly does not work with a gravity drain system.
Soap build up
Soap buildup occurs mostly in secondary drains like showers, lavatories and laundry drains. As the soap is carried down the drain, it will, over time accumulate on the walls of the pipe. Although this happens slowly, the water can back up very suddenly as the drain pipe is reduced in diameter by the buildup.
Grease build up
Grease buildup occurs just like soap buildup, only much faster. This occurs mostly in kitchen sink drains. As the grease is carried down the pipe by hot water from rinsing dishes and dishwashers, it is cooled by the vent pipes allowing cold air into the drain system. When the hot grease cools, it sticks to the pipe walls restricting the amount of water the pipe can drain.
Are your drains or sewer pipes not flowing or flowing slowly? They may be clogged. Avoid the temptation to use caustic chemicals found in most hardware stores. They are less effective at removing most clogs and over time can add to the damage of older pipes.
We recommend starting with cabling solutions and hydro-jetting for cleaning the build up on the inside of pipe walls.
