What Shapes Clogs in Cornwall
Local numbers that matter for drains here, each with its source.

What the borough asks you not to flush
Cornwall Borough's FOG page explains that grease washed down the sink ends up in the sewer, and that even flushable wipes only break down into smaller pieces. Grease cools and sticks to the inside of the kitchen line, and wipes snag on it. Together they make the classic Cornwall kitchen sink clog: slow for a week, then standing water in both bowls.

Newer subdivisions and older villages
Half of all Cornwall homes were built before about 1986, Census estimates show, and about 35% were built in 2000 or later, mostly in newer developments. About 18% predate 1940 in the older village areas. Newer PVC lines rarely fail on their own, so a backup in a new house is usually something flushed. In the older homes, root intrusion and old cast iron are more likely.

Laterals run from the mains
The borough's well and digging page reminds residents that water service lines and sewer laterals run from the mains to each house, and to call 811 (PA One Call) before digging. If a plumber needs to dig up a broken lateral, the utility marking comes first. For a regular clog, a cleanout and a drain machine usually do the job without digging.

Before the Plumber Arrives in Cornwall
Skip the chemical drain cleaner. It can splash back and it can't clear a main line.
- Stop running water if more than one drain is backing up.
- Don't pour chemical cleaner into standing water. It can splash back when the plumber opens the line.
- If you know where the cleanout is, clear the area around it.
- Keep children and pets away from dirty water.
