Connecticut plumbing FAQ

How do I check a plumber's license in Connecticut?

The Connecticut Department of Consumer Protection licenses plumbers (P-1 contractors and P-2 journeymen); you can verify a license online.

Do pipes freeze in Connecticut?

Yes, regularly. Connecticut winters freeze pipes in exterior walls, crawl spaces, garages and attics, and outdoor spigots that aren't frost-free. Keep the heat on, disconnect hoses in fall and know where your main shutoff is.

Is Connecticut water hard?

Generally soft, based on national hardness mapping, but it varies by utility and by well. Your water provider's annual water quality report lists the hardness for your system, and a plumber can test well water.

How old are homes in Connecticut?

Census estimates for Connecticut put 41% of homes as built before 1960, 27% from 1960 to 1979, 21% from 1980 to 1999 and 12% in 2000 or later. Older homes are more likely to have galvanized supply pipe and cast iron or clay sewer lines.
