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.

Hello I had a plumber do an estimate for me to replace our copper pipes with plastic as we have no existing walls up in our basement yet...pretty basic job... so we figured we could upgrade as we do live in Northern Ontario and it does tend to get quite cold here in the winters.  We dont have any existing problems with our plumbing right now just figured it would be good time to do the job and perhaps change the pipes to 3 quarter inch for faster flow.  Well I never thought in all my life I would get an estimate back that would state $350.00 an hour in labor...yes that is correct $350.00 an hour...estimated 10 hours for the job to be completed.  So he quoted me $3500.00 for labor alone.. not supplies?  Well needless to say I will be happy with my half inch copper pipes and will happily wait for my bathtub to fill up at a slower pace.  Just wanted to know what your thoughts are on this $350.00 an hour quote?  Thank you and enjoy your day.
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!
