Type "L" hot and cold water copper lines?
I'm using type L instead of type M copper for re-piping my whole house where
only M is required by code. Mostly it will be installed in the crawl space below a wood structure. Am I wasting my money or will it provide better reliability say 20 to 30 years from now. |

M and L thicknesses come in rigid pipe, while K comes in bendable tubing like the stuff often used for the burried incoming supply line. -- Calvin Henry-Cotnam "I really think Canada should get over to Iraq as quickly as possible" - Paul Martin - April 30, 2003 ------------------------------------------------------------------------- NOTE: if replying by email, remove "remove." and ".invalid" *** Posted via a free Usenet account from http://www.teranews.com *** |

They require K for gas. Reliability 20 years from now is not the issue; if everything is done correctly and not subsequently damaged, either will be fine. It is just that M will be damaged by things that don't bother L. (Sad but true, a year ago I nicked a pipe while putting up a partition wall. Made no difference to the L, but probably would have ruptured M.) Even if your code doesn't require it, it seems like a good investment. |

Type "L" hot and cold water copper lines?
Had a short length of pipe in my garage that went from the house to an
outside faucet. Even though I drained it, type "M" pipe split open like aluminum foil over winter. There couldn't be more than a few drops of water in the line but it split three winters in a row. I changed it to type "L" and had no problems with it since. I am sold on the durability of type "L".

I'd also wager that the thicker pipe is more immune to the pinhole leak
problem from additives that has plagued some areas of the country. -- Bobby G. "EXT" wrote in message anews.com...

In addition to better resistance to the forces of freezing (pressure inside
the pipe) and corrosion (developing pinhole leaks) you can also add resustance to crushing especially if buried or clamped hard. "Robert Green" wrote in message ...

Then you would be really impressed with type "K"
We used type L strictly for heating, and K for all water lines hot or cold...........

go with the thicker gauge, but also increase the pipe size to at least
3/4" everywhere for good flow thru unrestricted full orifice ball valves. our water is coming off a new 1" main with only 42psi. buffalo ny. |
