Yes i do agree any time you can save money is good...Waht do you think about PEX and have you used it for any projects.

A brand new house will NEVER be built with type L copper. Every residential guy on the planet uses type M copper whether it's in a wall or ceiling or exposed. Type L copper is primarily used for commercial applications and anything outside should be "L" and anything underground should be type K(the thickest). I've never heard of type "N". Type "dwv" is for drain waste and vent.

@PLUMBdogg no type L is used for domestic water hot cold supply in or out of walls in residential and commercial applications,,, type M is used for hydronic heating baseboard/ hydro airs systems,,, K is used for A/C or under ground supply water here in New York ,,,Not my rules they are set by the national trade standards of codes,,, And I like your videos thank you for sharing,,,

@Jerry2665 Thanks. I should've clarified myself. Not that it can't be done with L, just that it's more expensive and for little added benefit in a "residential" application. I just figured someone should say something to save anyone from watching this vid from throwing out the cash for L when M is just fine.
