Hello @ken2 

Using blue line pipe is ok to use from the meter to the house. However you must use a more permanent fixture from the front of your house going in. Blue line pipe uses Philmac fittings and they deteriorate over time, this is why it is easy to fit and remove and replace. They are usually installed in an exposed setting outside walls or just buried under ground. You can get to it with minimal effort. Fittings in the wall present a whole new challenge. It must maintain its strength and must provide a solid seal against water leaks. Grey crimp on fittings with aluminum collars, smartex fittings, sharkbite and other brands provide easy push on fittings with dependable reliability and provide good service. We can't ignore traditional copper as a tried and tested replacement for galvanized fittings. It will all depend on your budget and how your going to go about replacing your fittings. Good luck and stay safe.

Cheers,
