Pro Plumbers

“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 assume that every Mr. Fix-it advertising his services in the local Pennysaver or on Craigslist is a licensed plumber,” says one New York plumber. There is no national standard for issuing licenses. Some plumbers are licensed by the state, others by the counties they work in. Check with your local city hall or chamber of commerce. They should be able to direct you to the appropriate source for a list of licensed plumbers in your area.

No plumber is going to come right out and explain that they don’t have the required license to work for you. So if you know someone who is a great plumber, but they don’t have a license, hire them at your own risk. Licensed plumbers know the local building codes and regulations, have completed a certain amount of hours on the job and are insured. Want to become a master plumber yourself? Here are 28 tips.
The thicknesses of the water pipe and tube walls can vary. Pipe wall thickness is denoted by various schedules or for large bore polyethylene pipe in the UK by the Standard Dimension Ratio (SDR), defined as the ratio of the pipe diameter to its wall thickness. Pipe wall thickness increases with schedule, and is available in schedules 20, 40, 80, and higher in special cases. The schedule is largely determined by the operating pressure of the system, with higher pressures commanding greater thickness. Copper tubing is available in four wall thicknesses: type DWV (thinnest wall; only allowed as drain pipe per UPC), type 'M' (thin; typically only allowed as drain pipe by IPC code), type 'L' (thicker, standard duty for water lines and water service), and type 'K' (thickest, typically used underground between the main and the meter). Because piping and tubing are commodities, having a greater wall thickness implies higher initial cost. Thicker walled pipe generally implies greater durability and higher pressure tolerances.
Most typical single family home systems won't require supply piping larger than 3⁄4 inch (19 mm) due to expense as well as steel piping's tendency to become obstructed from internal rusting and mineral deposits forming on the inside of the pipe over time once the internal galvanizing zinc coating has degraded. In potable water distribution service, galvanized steel pipe has a service life of about 30 to 50 years, although it is not uncommon for it to be less in geographic areas with corrosive water contaminants.
Although needing emergency service for anything is never fun, if its plumbing service you ned I’d recommend Ben Franklin. The customer service person that took my call was courteous and professional. The service technician arrived well within the appointment time window. He was also courteous and professional. He understood my issue and explained what service was needed and what it would cost. He fixed the problem, cleaned up any debris that occurred during his work. We did the paperwork, he asked if I had any questions and then gave me his contact information in case I needed to call. You can’t beat that! Thanks!

Sometimes a faucet leak can be stopped by replacing the rubber washer at the end of a faucet stem or cartridge.  This is a more common repair on older fixtures when things were built to last and designed to be able to be maintained.  Other times the whole stem or cartridge needs replacement or the bibb seat deeper back into the fixture needs replacement.  That leads to matching up the right components and often times making a trip to the hardware store or plumbing supply house necessary due to the many varieties, makes and models of faucets.  My advice is to make sure your Plumber has faucet repair kit on their truck before having them come out to assess the issue.

Water systems of ancient times relied on gravity for the supply of water, using pipes or channels usually made of clay, lead, bamboo, wood, or stone. Hollowed wooden logs wrapped in steel banding were used for plumbing pipes, particularly water mains. Logs were used for water distribution in England close to 500 years ago. US cities began using hollowed logs in the late 1700s through the 1800s. Today, most plumbing supply pipe is made out of steel, copper, and plastic; most waste (also known as "soil")[21] out of steel, copper, plastic, and cast iron.[21]


Toilets – Sometimes toilet drains are overwhelmed with toilet paper or clogged by non-flushable items that find their way into the drain. Roto-Rooter can clear any toilet drain to restore full drainage and powerful flushes. Our skilled plumbers can also fix problems related to running toilets, leaking toilets, broken tanks and bowls, and toilets that don’t flush properly.

The word "plumber" dates from the Roman Empire.[3] The Latin for lead is plumbum. Roman roofs used lead in conduits and drain pipes[4] and some were also covered with lead, lead was also used for piping and for making baths.[5] In medieval times anyone who worked with lead was referred to as a plumber as can be seen from an extract of workmen fixing a roof in Westminster Palace and were referred to as plumbers "To Gilbert de Westminster, plumber, working about the roof of the pantry of the little hall, covering it with lead, and about various defects in the roof of the little hall".[6] Thus a person with expertise in working with lead was first known as a Plumbarius which was later shortened to plumber.
