copper pipe vs pex
 
I have just bought an acreage and the house was built in 1983. The house has copper pipe in it type M. I am upgrading to high efficieny hot water heater, furnace etc. I have to upgrade the size of the pipe to facilitate better water pressure coming out the hot water tank. I have had a number of quotes which most of them want to upgrade all piping to pex. At this time I have no leaks and the copper piping is in good condition. Should I upgrade to type K or L piping or redo with pex(I still have to change some of the pipe to 3/4 inch)? I have knowlege that mice and rats can eat through the plastic and that over time plastic becomes brittle. Since I live on an acreage I do have mice. I know it will cost a bit more for copper and I'm willing to pay the extra to know I won't be calling a plumber for leaks. This is a typical 1100 sq ft bi-level. I would like some advice on this as it is confusing as to what product will suit my situation.

If you are going to use copper for domestic water, use type L. PEX is a great product, only once have I seen rodents chew on PEX and the crwal space was infested with mice. The nice thing abour PEX is that if you have frozen pipes, PEX will not burst. When you upgrade your water heater make sure you do not use Whirlpool (lots of problems). Best of luck.

I used to like the idea of PEX until I saw the price of the crimping tool:eek:
Times have changed and with the invention of sharkbites I am a big fan now. I can feed PEX to a standard copper fixture, ie,: toilet shutoff and have it secured.

Depending on the size of your project, a tool might be cheaper anyway. Sharkbites can get up to 3x the cost of a pex fitting, and you're not allowed to have them in concealed locations that I know of.

If you're on an untreated well system, i'd recommend pex over copper. It will last a long time. Pex doesn't get brittle that I know of unless exposed to uv for a long period of time.

As for copper, make sure it's well insulated after installation to prevent bursting during cold snaps.

K copper is generally used for underground water service,We normally use L on commercial plumbing and M for residential
