Wall thickness does not affect pipe or tubing size.[20] 1/2" L copper has the same outer diameter as 1/2" K or M copper. The same applies to pipe schedules. As a result, a slight increase in pressure losses is realized due to a decrease in flowpath as wall thickness is increased. In other words, 1 foot of 1/2" L copper has slightly less volume than 1 foot of 1/2 M copper.[citation needed]

I had called Ben Franklin to fix a pin hole leak in the meter horn. Booking an appointment was very easy and the crew (Sid and Brandon) showed up on time. They quickly found out that a stop valve was not working and had to be replaced as well. Sid clearly explained my options and the charges upfront. He dealt with the city for water shut off, went about the job in a quick and efficient manner. Sid was very professional and explained clearly what he was doing. He patiently answered all my questions. Brandon was very practical and frank. As they were finishing up (I had to leave the house for an hour) they spotted a leak in another valve and fixed that also. I thought it was highly ethical of them to do so. Thank you Sid and Brandon!

"lead hung on a string to show the vertical line," early 14c., from Old French *plombe, plomee "sounding lead," and directly from Late Latin *plumba, originally plural of Latin plumbum "lead (the metal), lead ball; pipe; pencil," a word of unknown origin, related to Greek molybdos "lead" (dialectal bolimos) and perhaps from an extinct Mediterranean language, perhaps Iberian.
I had another lady who said she wanted to run to the grocery store to get some coffee to make for me and my guys while we were installing her new kitchen. She said she was just gonna run to the store and asked if we wouldn’t mind keeping an eye out for her one-year-old daughter who was sleeping at the time. We said fine, but she ended up not returning until four hours later. The kid was screaming her head off and we didn’t know what to do. We tried holding her. We didn’t know if she was hungry or what to feed her. She just kept crying.

“Central Penn Plumbing provided outstanding customer service. On a cold winter Saturday morning, we woke up to a very cold house. I gave Central Penn (Scott) a call and within an hour he had a service technician at our house to address the issue. Not only did they resolve the issue on the weekend, but Scott stopped by later in the week to ensure that things were still ok. Outstanding customer service. Thanks Central Penn Plumbing Services!”

 CON'T FROM COMMENTS EARLIER.  However,  the  installation took less than 3/4/ hour and was a basic regulator with no other function.  Looking up the price afterwards, invoice did not list type or price, it appears that it would have cost me around $60 for the regulator and another $15 or so for the additional supplies necessary to install it and it was really a rather simple job with easy access.    Given that, it seems that $300 for less that  an hours worth of on site work,  company says it does not include commute time in its prices, is a little high.  While flat rate quotes are nice, they must take into consideration situations where the work load differs depending on the circumstances.  Therefore, unless you are at the upper end of the harder work needed than the average job. it can be argued that my estimated price of $300 for labor was more than a little high.  Maybe I am wrong since I have not used their services for years and  am not knowledgeable of the costs of equipment and professional labor today.  
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]
