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]

PVC/CPVC – rigid plastic pipes similar to PVC drain pipes but with thicker walls to deal with municipal water pressure, introduced around 1970. PVC stands for polyvinyl chloride, and it has become a common replacement for metal piping. PVC should be used only for cold water, or for venting. CPVC can be used for hot and cold potable water supply. Connections are made with primers and solvent cements as required by code.[22]
Awesome experience with Charlie's Rooter Service! Our outside area drains were overflowing when it rained and about to flood toward the house.  I called Charlie's and they had Luis come over within an hour.  Luis was super friendly and ready to help when he arrived.  He figured out the problem and snaked the street drain and pulled out a huge clump of roots that were clogging it up!  But there was still some backup flooding on the side that he was able to isolate to get rid of the mud and debris that were clogging that up.  Before leaving, Luis even gave suggestions on how to flush it out periodically to keep things flowing smoothly.  Luis is the best and I would definitely use him for future plumbing problems, highly recommended!
