Pro Plumbers

Cast iron and ductile iron pipe was long a lower-cost alternative to copper, before the advent of durable plastic materials but special non-conductive fittings must be used where transitions are to be made to other metallic pipes, except for terminal fittings, in order to avoid corrosion owing to electrochemical reactions between dissimilar metals (see galvanic cell).[17]

“I have used Central Penn for many repairs/installs over the last 15 years. They have always responded in a prompt manner and I found their people to be very friendly, efficient and competent in diagnosing and repairing any issues I had, whether related to plumbing or HVAC. Furthermore, which you can’t take for granted these days, the guys are very respectful of your home and are careful in their work and thoroughly clean up after the job is completed.”
“Don’t go to the Yellow Pages to find a plumber,” says Berkey’s Bill Stevens. “It’s like guessing lottery numbers. Anyone can make an appealing ad, but that doesn’t mean they are legitimate. In this industry, it’s easy for a plumber who develops a poor reputation to advertise under a different name. They come and go.” Even searching for someone online may end up being a scam using fake reviews. Instead, look for a plumber who is well-established in your community. Check the Better Business Bureau and read customer reviews at sites such as HomeAdvisor, Angie’s List, or Citysearch. Local contractors or plumbing fixture stores can also refer you to a quality plumber, according to Grady Daniel, who owns a plumbing company in Austin, Texas. “Most of these firms won’t work with bad plumbers.” Or simply ask your neighbors for a referral. A trusted plumber that consistently delivers quality service does not remain a secret for very long.
The difference between pipes and tubes is simply in the way it is sized. PVC pipe for plumbing applications and galvanized steel pipe for instance, are measured in IPS (iron pipe size). Copper tube, CPVC, PeX and other tubing is measured nominally, which is basically an average diameter. These sizing schemes allow for universal adaptation of transitional fittings. For instance, 1/2" PeX tubing is the same size as 1/2" copper tubing. 1/2" PVC on the other hand is not the same size as 1/2" tubing, and therefore requires either a threaded male or female adapter to connect them. When used in agricultural irrigation, the singular form "pipe" is often used as a plural.[19]

Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids.[1] Heating and cooling (HVAC), waste removal, and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications.[2] The word derives from the Latin for lead, plumbum, as the first effective pipes used in the Roman era were lead pipes.[3]
