A slow drain is annoying. A drain that keeps backing up is telling you something about the pipe, and it is worth knowing which one you have.
Older homes: the pipe has narrowed
Cast iron drains in the older neighbourhoods build up a thick layer inside over the decades. A cable pushes a hole through the blockage but leaves that layer behind, which is why the problem comes back sooner each time. Jetting washes the buildup off the pipe walls properly.
Newer homes: something got in there
In the newer areas off Bees Ferry and Savannah Highway the pipe is fine. Blockages there are almost always grease, wipes labelled flushable that really are not, or leftover debris from when the house was built. That last one catches people out in a house barely twenty years old.
The kitchen is usually first
Cooking oil goes down warm and cools solid further along the line. It is the single most common cause of a kitchen drain that keeps clogging, and it builds up quietly over months.
When it is worth looking inside
If a drain has backed up more than once, a camera tells you whether you are cleaning a good pipe or putting off replacing a failing one. That is worth knowing before you spend anything.
